“…Apart from these, some other alternatives have also been reported such as band-gap engineering and creating sulfur vacancies (SVs). 23 Band-gap engineering plays a crucial role in achieving an appropriate phase, and facilitating the effective separation of charge carriers. Yu et al , reported cubic-phase CdS nanocrystals that were rich in sulfur, and which gave a hydrogen production rate of 680 μmol g −1 h −1 .…”

BackgroundCatalyst synthesis plays a crucial role in advancing photo and electrocatalysis technologies for sustainable development. However, the traditional thermal radiation heating method suffers from the disadvantages of high energy consumption, low heat transfer efficiency, slow heating speed and long heating time, which leads to the inefficiency and cost increases in catalyst preparation.AimsThe Joule‐heating ultrafast synthesis method with rapid heating/quenching and shorter heating time has attracted much attention. Despite its potential, there is a lack of comprehensive reviews specifically addressing the synthesis of advanced photo and electrocatalysts via Joule‐heating. Therefore, this review aims to help people quickly understand the advantages of Joule‐heating in the synthesis of photo and electrocatalysts.DiscussionHerein, we firstly introduce the principles and devices of Joule‐heating, and then we discuss breakthroughs in defect modulation, heterojunction construction, single‐atom catalysts, bimetallic alloy catalysts, high‐entropy alloy catalysts and metastable catalysts achieved through Joule‐heating technology. The diverse applications of these catalysts include hydrogen evolution, oxygen evolution, oxygen reduction reactions, carbon dioxide reduction reactions, nitrogen reduction reaction and degradation of organic pollutants. Furthermore, this review provides a forward‐looking perspective on future directions for employing Joule‐heating methods in the field of photo and electrocatalysis research.ConclusionThis review highlights the pivotal role played by Joule‐heating techniques in advancing nanomaterial synthesis as well as developing sustainable high‐performance catalyst systems.
