Publication date: 19th December 2024
Electrolysis technologies such as water splitting, CO2 electroreduction, and other emerging reactions, present sustainable alternatives to power large industries such as transport (fuels), manufacturing (chemical feedstock) and agriculture (fertilizers). The viability of these technologies hinges upon achieving sufficient achieving sufficient performance in metrics such as product selectivity, productivity (or current density), energy efficiency, and stability, at scale. Conventionally, improvements in these reactions have been sought by tuning the electronic and physicochemical properties of (pre)catalysts through compositional and structural modifications. Here, I will show approaches to tune electrocatalytic activity in water-based electrolysis by manipulating precatalyst reconstruction and reaction environment, addressing the liquid-side of the reaction. I will discuss the need of tailored activation protocols and situ and operando spectroscopies at relevant working conditions to achieve reliability in catalyst design and operation. To conclude, I will overview sustainability issues in the scale up and path to market of CO2 electrolysis technologies.
