Electro- and Photoelectrocatalysis

Photoelectrocatalysis (PEC) and electrocatalysis (EC) are promising strategies towards a sustainable energy future. The rapid progress in these fields is enabling the development of innovative technologies for producing fuels and chemicals through processes such as water splitting, CO2 reduction, and N2 reduction, all of which can be powered by renewable energy sources. These developments provide a pathway to reduce CO2 emissions, mitigate environmental impacts, and decrease reliance on fossil fuels. While laboratory-scale demonstrations of PEC and EC have been successful, constructing large-scale systems suitable for practical applications remains challenging. This requires continued breakthroughs in both catalyst design and system optimization.

This special issue seeks to highlight the latest breakthroughs in PEC and EC research, showcasing novel catalyst materials, advancements in device design, system integration strategies, and reviews of the theoretical frameworks underpinning these technologies. By sharing these cutting-edge developments, the issue aims to encourage further exploration and inspire the new solutions needed to unlock the full potential of PEC and EC in achieving energy sustainability and addressing climate goals.
