Highly Effective OER Electrocatalysts Generated from a Two-Dimensional Metal–Organic Framework Including a Sulfur-Containing Linker without Doping

“…Researchers are currently focusing on developing non-precious-metal electrocatalysts. Carbides produced from first transition series metals, sulfides, and other compounds have shown promise for use in water electrolysis. − Cobalt, for example, is abundant, inexpensive, and has a unique 3d electron configuration. Its derivatives, such as cobalt oxide, cobalt sulfide, cobalt selenide, and cobalt nitride, have piqued researchers’ interest as catalysts because of their superior electrochemical properties. − Transition-metal sulfide (TMS) has attracted a lot of attention because of its low cost, strong catalytic activity, outstanding operational stability, and especially its distinctive 2D layer. − The 2D nanosheets, on the other hand, will experience irreversible aggregation due to van der Waals pressure, drastically reducing the specific surface area and affecting their electrochemical characteristics. − As a result, one of the viable ways of exploring efficient electrocatalysts is to develop matching sulfide materials utilizing effective templates. − …”

Facile fabrication of self-supporting porous CuMoO4@Co3O4nanosheets as a bifunctional electrocatalyst for efficient overall water splitting

“…14,15 To boost the reaction kinetics and reduce the overpotentials of the HER and OER electrodes, efficient and durable electrocatalysts are needed. 16 At present, although noble metal-based electrocatalysts, such as RuO 2 , IrO 2 and Pt-C, have excellent OER and HER properties, 17 the rareness and high cost of noble metal catalysts limit their application and promotion. 18 Designing cost-effective HER cathode and OER anode electrocatalysts utilizing plentiful non-noble metals is the crux to achieving clean hydrogen energy in a water splitting system.…”
