Countercation Manipulation Enables Selective Electrochemical CO2‐to‐Formate Conversion Over Bi‐Polyoxometalate‐Derived Catalysts

Chemistry – A European Journal, EarlyView.
Ba2+ salt of Bi‐incorporated polyoxometalate (POM), Bi4 ([Bi4O(γ‐SiW10O36)2(OAc)]7−), immobilized on a carbon support (Ba‐Bi4/C) functioned as a formate (HCOO−)‐selective catalyst for electrochemical CO2 reduction reaction (CO2RR). The incorporation of Ba2+ and the formation of highly dispersed Bi species were the key factors for Ba‐Bi4/C to achieve ...

A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

EcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)
