Applications of Metal–Organic Frameworks and Their Derivatives in Electrochemical CO2 Reduction

Nano-Micro Letters (2023)

Chengbo Li Yuan Ji Youpeng Wang Chunxiao Liu Zhaoyang Chen

Abstract Electrochemically reducing CO 2 to more reduced chemical species is a promising way that not only enables the conversion of intermittent energy resources to stable fuels, but also helps to build a closed-loop anthropogenic carbon cycle. Among various electrocatalysts for electrochemical CO 2 reduction, multifunctional metal–organic frameworks (MOFs) have been employed as highly efficient and selective heterogeneous electrocatalysts due to their ultrahigh porosity and topologically diverse structures. Up to now, great progress has been achieved in the design and synthesis of highly active and selective MOF-related catalysts for electrochemical CO 2 reduction reaction (CO 2 RR), and their corresponding reaction mechanisms have been thoroughly studied. In this review, we summarize the recent progress of applying MOFs and their derivatives in CO 2 RR, with a focus on the design strategies for electrocatalysts and electrolyzers. We first discussed the reaction mechanisms for different CO 2 RR products and introduced the commonly applied electrolyzer configurations in the current CO 2 RR system. Then, an overview of several categories of products (CO, HCOOH, CH 4 , CH 3 OH, and multi-carbon chemicals) generated from MOFs or their derivatives via CO 2 RR was discussed. Finally, we offer some insights and perspectives for the future development of MOFs and their derivatives in electrochemical CO 2 reduction. We aim to provide new insights into this field and further guide future research for large-scale applications.

Facile preparation of Ag nanocubes at 30°C under light irradiation

Micro & Nano Letters (2018)

Danli Li Yangyang Shan Ruiyi Liu Qian Wu Tingting Zheng

Preparation of silver nanocubes (Ag NCs) with low temperature and controlled shapes is challenging in an aqueous solution because of its anticipated low embodied energy and experiment controllability. In this work, Ag NCs have been successfully synthesised under facile reaction conditions (at 30°C oil bath and under daylight illumination) by coordination effects of thermal reduction and photoinduced reduction. The obtained Ag NCs were characterised by transmission electron microscopy, UV–visible spectrophotometer and X‐ray diffractometer. It turned out that, Ag NCs were prepared by using trifluoroacetic acid silver, cetyltrimethyl ammonium chloride, ascorbic acid, ferric chloride and sodium hydrosulphide as raw materials, and their sizes around 35 nm. Besides, as‐synthesised Ag NCs with uniform size and high yield would serve as outstanding substrates for surface‐enhanced Raman scattering detection, and as sacrificial templates to fabricate Au nanocages.

Superhydrophobic, Multifunctional, and Mechanically Durable Carbon Aerogel Composites for High-Performance Underwater Piezoresistive Sensing

ACS Applied Materials & Interfaces (2024)

Mingzhou Yang Jing Wen Jiang Han Tingting Zheng Xinxin Li

Carbon aerogel piezoresistive sensors (CAPSs), owing to their good thermal stability, self-constructed conductive network, and fast response to pressure, have attracted extensive attention in the field of flexible and wearable electronics in recent years. However, it is still a great challenge for CAPSs to monitor subtle deformations and achieve high-performance underwater piezoresistive sensing. Herein, a superhydrophobic and electrically conductive carbon aerogel composite (CAC) was fabricated by the combination of fluorination of carbon aerogels and decoration of fluorinated halloysite nanotubes (HNTs). Due to the exceptional light absorption and excellent photothermal conversion performance, CAC has a fast and accurate response to temperature with a high-temperature coefficient of resistance (TCR) of −1.06%/°C. The resistance of CAC exhibits a linear response toward compressive strain up to 80% with a high gauge factor of −1.24. Significantly, the CAC sensor can effectively detect tiny deformations, thanks to its excellent waterproof performance, and it enables stable output of sensing signals in an underwater environment. This work provides new insights into the development of superhydrophobic, multifunctional, and mechanically durable piezoresistive sensors with potential applications in underwater flexible electronics.

Intercalated Iridium Diselenide Electrocatalysts for Efficient pH‐Universal Water Splitting

Angewandte Chemie International Edition (2019)

Tingting Zheng Chunyan Shang Zhihai He Xinyi Wang Cong Cao

Developing bifunctional catalysts for both hydrogen and oxygen evolution reactions is a promising approach to the practical implementation of electrocatalytic water splitting. However, most of the reported bifunctional catalysts are only applicable to alkaline electrolyzer, although a few are effective in acidic or neutral media that appeals more to industrial applications. Here, a lithium-intercalated iridium diselenide (Li-IrSe2 ) is developed that outperformed other reported catalysts toward overall water splitting in both acidic and neutral environments. Li intercalation activated the inert pristine IrSe2 via bringing high porosities and abundant Se vacancies for efficient hydrogen and oxygen evolution reactions. When Li-IrSe2 was assembled into two-electrode electrolyzers for overall water splitting, the cell voltages at 10 mA cm-2 were 1.44 and 1.50 V under pH 0 and 7, respectively, being record-low values in both conditions.

Expansion and persistence of antibiotic-specific resistance genes following antibiotic treatment

Gut Microbes (2021)

Kang Kang Lejla Imamovic Maria-Anna Misiakou Maria Sørensen Yoshitaro Heshiki

Oral antibiotics are commonly prescribed to non-hospitalized adults. However, antibiotic-induced changes in the human gut microbiome are often investigated in cohorts with preexisting health conditions and/or concomitant medication, leaving the effects of antibiotics not completely understood. We used a combination of omic approaches to comprehensively assess the effects of antibiotics on the gut microbiota and particularly the gut resistome of a small cohort of healthy adults. We observed that 3 to 19 species per individual proliferated during antibiotic treatment and Gram-negative species expanded significantly in relative abundance. While the overall relative abundance of antibiotic resistance gene homologs did not significantly change, antibiotic-specific gene homologs with presumed resistance toward the administered antibiotics were common in proliferating species and significantly increased in relative abundance. Virome sequencing and plasmid analysis showed an expansion of antibiotic-specific resistance gene homologs even 3 months after antibiotic administration, while paired-end read analysis suggested their dissemination among different species. These results suggest that antibiotic treatment can lead to a persistent expansion of antibiotic resistance genes in the human gut microbiota and provide further data in support of good antibiotic stewardship.Abbreviation: ARG - Antibiotic resistance gene homolog; AsRG - Antibiotic-specific resistance gene homolog; AZY - Azithromycin; CFX - Cefuroxime; CIP - Ciprofloxacin; DOX - Doxycycline; FDR - False discovery rate; GRiD - Growth rate index value; HGT - Horizontal gene transfer; NMDS - Non-metric multidimensional scaling; qPCR - Quantitative polymerase chain reaction; RPM - Reads per million mapped reads; TA - Transcriptional activity; TE - Transposable element; TPM - Transcripts per million mapped reads.

Integration of CO₂ Capture and Electrochemical Conversion

ACS Energy Letters (2023)

Qing Xia Kouer Zhang Tingting Zheng Liang An Chuan Xia

Integration of CO2 capture and CO2 conversion through electrochemical processes has emerged in recent years, offering a distinct advantage over the traditional independent methods by obviating the costly capture media recovery and compression steps. This review aims to provide a comprehensive overview of this promising research area. State-of-the-art studies of strategies involving independent processes, coupling in a single electrolytic cell, and integration into two electrolytic cells for CO2 capture and conversion are discussed. Furthermore, the energy and production costs for three alternative methods are assessed and compared to highlight the benefits of integration systems. In addition, our personal perspectives on the challenges and opportunities in this emerging field, including achieving high faradic efficiency and low cell voltage, seawater exploration, and membrane-less configuration for high-durability applications, are presented.
