Single Atom Catalysts for Photoelectrochemical Water SplittingHo Won Jang aa Seoul National university, 대한민국 서울특별시 관악구 관악로 1, Korea, Republic ofMaterials for Sustainable Development Conference (MATSUS)Proceedings of MATSUS Spring 2024 Conference (MATSUS24)#SUSEN - Advances in Green Energy CarriersBarcelona, Spain, 2024 March 4th - 8thOrganizers: Ungyu Paik and Kangli WangInvited Speaker, Ho Won Jang, presentation 375DOI: https://doi.org/10.29363/nanoge.matsus.2024.375Publication date: 18th December 2023Single atom catalysts (SACs) have attracted increasing attention in electrocatalysis due to their unprecedented catalytic activity with excellent atomic utilization efficiency derived from unique electronic states and coordination environments. In photoelectrochemical (PEC) water splitting, atomically dispersed metal catalysts anchored to photoelectrodes offer the breakthrough to outperform the conventional thin-film PEC catalysts by enlarging the catalytic sites and facilitating photogenerated charge carrier kinetics. Herein, we present a comprehensive review of SAC-incorporated photoelectrodes for efficient PEC water splitting. Firstly, the representative characterization techniques for the identification of SACs and investigations in respect of photogenerated charge carrier kinetics and photon-to-current efficiency will be discussed. Then, we will introduce the state-of-the-art PEC-SACs classified into noble metal, non-noble metal, and dual metal SACs. Finally, critical outlooks to realize the full potential of SACs in photoelectrocatalysis will be highlighted. Several hurdles that hinder the fabrication and identification of SAC-incorporated photoelectrodes will be discussed. Overcoming these obstacles will pave the way for the widespread adoption of SACs in PEC systems, revolutionizing the field of hydrogen energy production. © FUNDACIO DE LA COMUNITAT VALENCIANA SCITOnanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009.
