Graphene-Based Catalysts for Electrochemical CO₂ Reduction Reaction
Paper
Field effects explain the unintuitive potential response of electrochemical oxygen evolution in acid
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.

An aqua regia-free chemical recovery and reprecipitation of Ir from IrOx catalysts: optimisation of the extraction efficiency using surface response methodology
This study introduces a microwave assisted aqua-regia-free recycling process for Ir from IrOx catalysts. The experimental Ir extraction efficiency measured is 83 ± 10%. The leached Ir solution was then precipitated to form ((NH4)2IrCl6).

A MXene-supported single atom catalyst selectively converts CO2 into methanol and methane
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.
About this collection
Defossilising and decarbonising the energy industry will be an important step in securing a sustainable future. Converting chemical energy to more usable forms is one approach that offers a sustainable alternative.
Electrocatalysis offers a method of overcoming the activation barriers of desired reactions and can make them economically viable at scales to make a difference to global climate change targets. In this way, it will be possible to achieve UN Sustainable Development Goals 7 (affordable and clean energy) and 13 (climate action).
