About this collection

Humanity is facing a significant and growing energy demand, necessitating a new energy paradigm built on clean and abundant renewable energy. Within this context, electrocatalysis and photoelectrocatalysis hold great promise for enabling renewable energies such as solar and wind power to overcome the transient nature of their energy output. Developing catalysts that operate efficiently and selectively, and that are also robust, has been the focus of much research. This special issue will bring together the latest advances in the fundamental and applied science addressing the synthesis, characterization, mechanisms, and performance of (photo)electrocatalysts for energy storage and conversion of small molecules into useful specialty and commodity chemicals and fuels.
Guest Edited by Abhishek Dey (ICAS, India), Frances Houle (LBNL, USA), Cara Lubner (NREL, USA), Marta Sevilla (CSIC, Spain) and Wendy Shaw (PNNL, USA), this collection includes metalloenzymes, molecular catalysts, and heterogeneous catalysts, and spans both experimental and theoretical efforts. Applied efforts are also covered as electrocatalysis is at the core of many energy storage technologies.
