Cu-based bimetallic electrocatalysts for CO2 reduction

Yufei Jia et al.

Summary: The extensive consumption of fossil fuels has led to a rapid increase in atmospheric CO2 levels, necessitating the development of a clean and efficient technology for CO2 conversion. Copper, as the only metal capable of catalyzing the conversion of CO2 to multi-carbon products, has attracted considerable attention. However, single copper-based catalysts suffer from slow reaction kinetics, low product selectivity, and poor stability, which can be addressed by introducing a second metal. This review summarizes recent progress in Cu-based bimetallic electrocatalysts for CO2 reduction, discussing the effects of composition and structure on their activity and selectivity, and outlining the challenges and prospects in this field.

Heterostructuring 2D TiO2 nanosheets in situ grown on Ti3C2Tx MXene to improve the electrocatalytic nitrogen reduction

Xiu Qian et al.

Summary: In this study, TiO2 nanosheets (NSs) grown on highly conductive Ti3C2Tx MXene were proposed to achieve electrocatalytic NH3 synthesis. Ti3C2Tx MXene promoted electron transfer, while in-situ formation of TiO2 NSs prevented stacking and increased surface area. The TiO2/Ti3C2Tx MXene catalyst exhibited high efficiency and strong electrochemical durability, with the nitrogen in the produced NH3 originating from the electrolyte's N2.
