Themed collection Electrocatalysis for Energy Conversion Reactions

This review presents a comprehensive review of graphene-based catalysts for eCO₂RR, highlighting optimization strategies, characterization techniques, applications, and future challenges.

We demonstrate the conversion of a reactive carbon capture solution into CO using electricity provided by thermoelectric generators. The temperature differences that exist on Mars or at geothermal sites on earth are both capable of driving reactive carbon capture and conversion.

This study shows for the first time that tetraazamacrocyclic complexes for the conversion of CO₂ and epoxides cyclic carbonates in ionic liquids. Using Ni(cyclam)Cl₂ and BMimBr, 100% conversion is achieved in 24 hours at −1.8 V vs. Ag/AgCl.

We show that the electrostatic destabilization due to the interaction of surface oxygen with the interfacial field on IrO₂ reduces Tafel slopes in acidic OER. This creates the erroneous impression of a non-electrochemical rate limiting step.

This study introduces a microwave assisted aqua-regia-free recycling process for Ir from IrO_x catalysts. The experimental Ir extraction efficiency measured is 83 ± 10%. The leached Ir solution was then precipitated to form ((NH₄)₂IrCl₆).

Single atom catalysts (SACs) supported on MXene have emerged as new-generation catalysts that exhibit unique properties and catalytic activity due to their tunable coordination environment and uniform catalytic active sites.
