NiFe Hydroxide Lattice Tensile Strain: Enhancement of Adsorption of Oxygenated Intermediates for Efficient Water Oxidation Catalysis

Angewandte Chemie International Edition (2018)

Daojin Zhou Shiyuan Wang Yin Jia Xuya Xiong Hongbin Yang

The binding strength of reactive intermediates with catalytically active sites plays a crucial role in governing catalytic performance of electrocatalysts. NiFe hydroxide offers efficient oxygen evolution reaction (OER) catalysis in alkaline electrolyte, however weak binding of oxygenated intermediates on NiFe hydroxide still badly limits its catalytic activity. Now, a facile ball-milling method was developed to enhance binding strength of NiFe hydroxide to oxygenated intermediates via generating tensile strain, which reduced the anti-bonding filling states in the d orbital and thus facilitated oxygenated intermediates adsorption. The NiFe hydroxide with tensile strain increasing after ball-milling exhibits an OER onset potential as low as 1.44 V (vs. reversible hydrogen electrode) and requires only a 270 mV overpotential to reach a water oxidation current density of 10 mA cm-2 .

Electrochemical Oxygen Reduction to Hydrogen Peroxide via a Two‐Electron Transfer Pathway on Carbon‐Based Single‐Atom Catalysts

Advanced Materials Interfaces (2020)

Kai Sun Wenwen Xu Xiao Lin Shubo Tian Wen‐Feng Lin

Abstract Electrochemical reduction of oxygen is considered as a new strategy to achieve decentralized preparation of hydrogen peroxide (H 2 O 2 ) in a green manner. As a promising new type of catalytic material, carbon‐based single‐atom catalysts can achieve wide‐range adjustments of the electronic structure of the active metal centers while also maximize the utilization of metal atoms, toward electrochemical production of H 2 O 2 from the selective two‐electron transfer oxygen reduction reaction (ORR). Herein, starting from the reviewing of characterizing methods and reaction mechanisms of ORR via two‐electron and four‐electron transfer pathways, the vital role of binding strength between OOH intermediate and active sites in determining the activity and selectivity towards H 2 O 2 production is revealed and illustrated. Currently reported carbon‐based single‐atom catalysts for H 2 O 2 production are systematically summarized and critically reviewed. Moreover, with the underpinning chemistry to improve the overall efficiency, three aspects concerning the central metal atoms, coordinated atoms, and environmental atoms are comprehensively analyzed. Based on the understanding of the most current progresses, some predictions for future H 2 O 2 production via electrochemical routes are offered, which include catalyst designs at atomic levels, new synthesis strategies and characterization techniques, as well as interfacial superwetting interaction engineering at electrode and device levels.

Superwetting behaviors at the interface between electrode and electrolyte

Cell Reports Physical Science (2021)

Mengxuan Li Jinshan Wei Longtao Ren Yajun Zhao Zhicheng Shang

Electrochemical reactions that take place at the interface between electrode and electrolyte involve charge transfer, mass transport, and phase transformation. Wetting or superwetting behaviors at multi-phase interfaces, including gas (bubbles), liquid (e.g., oil droplets), or solid (e.g., islands or film) states, largely interfere with the performance of related electrochemical energy conversion and storage devices, industrial production, and environmental protection. In this review, recent progress is summarized on interfacial interactions and the consequent superwetting behaviors at the electrode-electrolyte interfaces, which determine the affinity to products and reagents, charge transfer resistance, coverage of active sites, and fading of electrodes at large overpotentials. Furthermore, the construction strategies of superwetting electrodes and the future opportunities and challenges in superwettability-mediated chemistry are proposed.

Research Progress of Oxygen Evolution Reaction Catalysts for Electrochemical Water Splitting

ChemSusChem (2021)

Yanying Liu Daojin Zhou Tianyin Deng Guangli He Aibing Chen

Abstract The development of a low‐cost and high‐efficiency oxygen evolution reaction (OER) catalyst is essential to meet the future industrial demand for hydrogen production by electrochemical water splitting. Given the limited reserves of noble metals and many competitive applications in environmental protection, new energy, and chemical industries, many studies have focused on exploring new and efficient non‐noble metal catalytic systems, improving the understanding of the OER mechanism of non‐noble metal surfaces, and designing electrocatalysts with higher activity than traditional noble metals. This Review summarizes the research progress of anode OER catalysts for hydrogen production by electrochemical water splitting in recent years, for noble metal and non‐noble metal catalysts, where non‐noble metal catalysts are highlighted. The categories are as follows: (1) Transition metal‐based compounds, including transition metal‐based oxides, transition metal‐based layered hydroxides, and transition metal‐based sulfides, phosphides, selenides, borides, carbides, and nitrides. Transition metal‐based oxides can also be divided into perovskite, spinel, amorphous, rock‐salt‐type, and lithium oxides according to their different structures. (2) Carbonaceous materials and their composite materials with transition metals. (3) Transition metal‐based metal‐organic frameworks and their derivatives. Finally, the challenges and future development of the OER process of water splitting are discussed.

Method of nanocarbon/montmorillonite powder extraction

Micro & Nano Letters (2014)

Jialun Tang Zepeng Zhang Daojin Zhou

In this reported work, carbon/montmorillonite (C/MMT) nanometre particles and micrometre particles blended were extracted by the froth flotation method, extraction and density gradient centrifugation. X‐ray diffraction, scanning electron microscopy, transmission electron microscopy and particle size analysis were employed to characterise the C/MMT extracted before and after. The results have shown that the froth flotation method cannot effectively collect C/MMT nanocomposites, and the extraction is not effective, whereas density gradient centrifugation can collect vari‐size grained C/MMT nanocomposite particles. On using density gradient centrifugation, the thicknesses of C/MMT nanocomposite particles are <20 nm.
