Bimetallic In ₂ O ₃ / Bi ₂ O ₃ catalysts enable highly selective CO ₂ electroreduction to formate within ultra‐broad potential windows

Energy & environment materials (2022)

Zhongxue Yang Hongzhi Wang Xinze Bi Xiaojie Tan Yuezhu Zhao

CO 2 electrochemical reduction reaction (CO 2 RR) to formate is a hopeful pathway for reducing CO 2 and producing high‐value chemicals, which needs highly selective catalysts with ultra‐broad potential windows to meet the industrial demands. Herein, the nanorod‐like bimetallic In 2 O 3 /Bi 2 O 3 catalysts were successfully synthesized by pyrolysis of bimetallic InBi‐MOF precursors. The abundant oxygen vacancies generated from the lattice mismatch of Bi 2 O 3 and In 2 O 3 reduced the activation energy of CO 2 to and improved the selectivity of to formate simultaneously. Meanwhile, the carbon skeleton derived from the pyrolysis of organic framework of InBi‐MOF provided a conductive network to accelerate the electrons transmission. The catalyst exhibited an ultra‐broad applied potential window of 1200 mV (from −0.4 to −1.6 V vs RHE), relativistic high Faradaic efficiency of formate (99.92%) and satisfactory stability after 30 h. The in situ FT‐IR experiment and DFT calculation verified that the abundant oxygen vacancies on the surface of catalysts can easily absorb CO 2 molecules, and oxygen vacancy path is dominant pathway. This work provides a convenient method to construct high‐performance bimetallic catalysts for the industrial application of CO 2 RR.

Catalytic Combustion of Methane over Noble Metal Catalysts

ACS Catalysis (2024)

Huimei Duan Fanxin Kong Xinze Bi Lei Chen Hangrong Chen

As one of the cleanest fossil fuel resources, methane is also the second largest greenhouse gas after CO2 owing to its strong greenhouse effect. The direct emission of large quantities of trace and unburned methane causes a serious energy loss and greenhouse effect. Catalytic methane combustion is a promising strategy in eliminating methane slip to address the urgent environmental issue. However, the current methane abatement catalysts still face great challenges in thermal stability, water resistance, and sulfur tolerance. In this review, we focus on the popular noble metal-based catalysts, discuss the distinct reaction mechanisms including the Langmuir–Hinshelwood model, Eley–Rideal model, Mars–van Krevelen model, and two-term mechanisms. The deactivation mechanisms induced by sintering, sulfur, and water on popular Pd-based catalysts are then analyzed. Then, we outline the promotion strategies from two aspects, i.e., construction of a core–shell structure and electronic engineering of the active phase to improve thermal stability and poisoning resistance. Finally, a summary and prospects with an emphasis on the newly developed oxide-metal interfaces and photothermal catalysis for highly efficient methane combustion are addressed.

Grain Boundaries Assisting Generation Abundant Cu+ For Highly Selective Electro-Reduction Co2 To Ethanol

Xinze Bi Yifan Yan Hongzhi Wang Yuezhu Zhao Mingbo Wu

It is highly desired yet challenging to strategically steer CO2 electroreduction reaction (CO2ER) toward ethanol (EtOH) with high activity and selectivity. Although the grain boundary (GB) has been identified as effective active site for C2 products formation, there is still no consensus on the mechanism governing its regulation. Moreover, the specific Cu species that plays a crucial catalytic role remains a source of debate. Herein, we report a kind of Cu7Se4/CuSe nanosheets with rich GBs that were conducive to generation abundant Cu+ species. Crucially, a clear correlation between Cu+ content and EtOH selectivity was obtained. The unique local charge distribution and electronic structure of Cu on GBs make it a real active site to promote EtOH production. This work elucidates the significant role of the Cu chemical state in CO2ER to EtOH, shedding light on the mechanistic insights of GBs serving as active sites for this process.

Electroreduction of CO ₂ to C ₂ H ₄ Regulated by Spacing Effect: Mechanistic Insights from DFT Studies

Energy Material Advances (2023)

Xinze Bi Yifan Yan Hongzhi Wang Yuezhu Zhao Jiatao Zhang

It is crucial to construct an efficient catalyst with high activity and excellent selectivity for realizing CO 2 electroreduction reaction (CO 2 ER) to high-value-added chemicals, especially the C2 products. Density functional theory (DFT) provides a powerful tool for investigating the promotional effect on C2 selectivity of finely tuned catalyst structures, which is currently difficult to control using experimental techniques, such as interatomic distances. In the work, 5 Cu 2 O catalyst models are constructed with different Cu-Cu atomic spacing ( d Cu - Cu ). The results of DFT calculations show that adjusting the d Cu - Cu can effectively tailor the electronic structures of active sites, enhance catalytic activity, and improve product selectivity. Specifically, the Cu atom pair spaced at d Cu - Cu = 2.5 Å could optimize the adsorption configuration of *CO and enhance the binding strength of *CO, thus improving *CO adsorption energy and reducing the energy barrier of C-C coupling. The work proves the feasibility of spacing effect in enhancing the C 2 H 4 selectivity of CO 2 ER and provides a new idea for the catalyst modification for other reactions of polyprotons-coupled electrons.

Inhibition Effect of Sulfation on the Activity of Pt/Tio2 Catalysts for Methane Combustion

Fanxin Kong Yonghao Wang Xinze Bi Jiabin Ji Lei Chen

The Pt/TiO2-S catalysts with SO42- modification were synthesized and employed for methane combustion. Experimental and theoretical studies reveal that the sulfation of TiO2 supports drastically aggravates the reduction of Pt2+→Pt0 in Pt/TiO2-S catalysts under the oxidizing atmosphere, weakens the adsorption of CH4, and raises the activation energy barrier of the initial C-H in CH4, leading to the severe deactivation of activity towards methane combustion.
