Two‐Dimensional Transition Metal Oxides and Chalcogenides for Advanced Photocatalysis: Progress, Challenges, and Opportunities

Sunlight‐driven catalytic reactions are appealing for resolving energy and environmental problems. Transition metal oxides (TMOs) and chalcogenides (TMCs) comprise one of the most popular categories of photocatalysts, thanks to their high stability, low cost, Earth abundance, and outstanding catalytic activity. Downsizing TMOs and TMCs to 2D materials offers additional opportunities to finely tune their surface, electronic, and catalytic...
