“…Furthermore, DFT calculations also confirmed that the electrical conductivity of CoP was mainly derived from Co atoms 102 . Luo et al 10 constructed CoP/g‐C 3 N 4 composites via the phosphorization of the Co 3 O 4 QDs/g‐C 3 N 4 precursor. The highest H 2 generation rate was 1.074 mmol h −1 g −1 , which is 283‐fold higher than that of pure g‐C 3 N 4 .…”

“…Metal phosphides are promising candidates to replace noble metals in photocatalytic H 2 production by water splitting due to their low hydrogen‐producing overpotential, tunable electronic structure, high electrical conductivity, and low price. For example, Ni 2 P, 9 CoP, 10 Cu 3 P, 11 MoP, 12 and FeP 13 have been demonstrated to be promising cocatalysts in photocatalysis.…”

Hydrogen evolution from water splitting over semiconductors has been considered one of the most promising ways to address energy shortages and environmental pollution. Searching for low‐cost, highly efficient, and durable catalysts is the key to improve the hydrogen production rate. Expensive noble metals, such as Pt and Au, are generally loaded onto semiconductors to promote photocatalytic activity. Metal phosphides are promising candidates to replace noble metals in hydrogen generation via electrocatalytic or photocatalytic water splitting due to their low hydrogen‐producing overpotential, tunable electronic structure, high electrical conductivity, and low price. In this review article, the characteristics and synthetic methods of metal phosphides are briefly introduced, and the development of metal phosphides for electrocatalytic or photocatalytic water splitting is presented. Finally, the challenges and future directions of metal phosphides are discussed.

“…Finally, after a phosphidation treatment with NaH 2 PO 2 under Ar atmosphere, all the cobalt‐related phase was converted into CoP while maintaining the morphological features of the corresponding precursors, that is, 0 D CoO and Co NPs are converted into 0 D CoP NPs encapsulated in the carbon structure, whereas 2 D Co(OH) 2 nanosheets are converted into 2 D CoP nanosheets. During this step, the interconnected 3 D architecture inherited from the last stage was well maintained (Figure ).…”

Non‐noble metal‐based bifunctional electrocatalysts are highly desired for water electrolysis. However, constructing a water electrolyzer using a sole catalyst without compromising either its oxygen evolution reaction (OER) or hydrogen evolution reaction (HER) performance is still challenging. In this study, a simple strategy is developed to integrate 2 D and 0 D CoP in the same metal–organic framework precursor‐derived hollow N‐doped carbon nanotube‐assembled polyhedron (HNCNP). The unique hierarchical structure endows the resulting nanocomposite with both the advantages of more exposed active sites for 2 D and large surface‐to‐volume ratio for 0 D materials, whereas the hollow interior could benefit the charge and mass transfer properties. Thus, CoP/HNCNP@2 D CoP exhibits outstanding OER and HER activity and a low cell voltage when employed as both the anode and cathode in a two‐electrode water electrolyzer. The approach of integrating the same metal phosphide phase with diverse dimensions may inspire new ways to design hierarchical nanostructures for advanced energy conversion applications.

“…In view of the 2D nature of g-C 3 N 4 , some 0D quantum dots (QDs) or ultrathin 2D materials always serve as highly effective cocatalysts to form the highquality heterojunction with g-C 3 N 4 . [92,93] Specifically, the reduced dimension endows cocatalysts with a high surface area, hence leading to more catalytic sites involved in HER. Using phosphorene as an example, the exfoliation of bulk black phosphorene into few-layer phosphorene contributed to improving the charge mobility and enlarging the specific surface area, thus leading to the fact that few-layer phosphorene as cocatalysts obviously improved the HER performance of g-C 3 N 4 .…”

Over the past few decades, graphitic carbon nitride (g‐C3N4) has arisen much attention as a promising candidate for photocatalytic hydrogen evolution reaction (HER) owing to its low cost and visible light response ability. However, the unsatisfied HER performance originated from the strong charge recombination of g‐C3N4 severely inhibits the further large‐scale application of g‐C3N4. In this case, the utilization of cocatalysts is a novel frontline in the g‐C3N4‐based photocatalytic systems due to the positive effects of cocatalysts on supressing charge carrier recombination, reducing the HER overpotential, and improving photocatalytic activity. This review summarizes some recent advances about the high‐performance cocatalysts based on g‐C3N4 toward HER. Specifically, the functions, design principle, classification, modification strategies of cocatalysts, as well as their intrinsic mechanism for the enhanced photocatalytic HER activity are discussed here. Finally, the pivotal challenges and future developments of cocatalysts in the field of HER are further proposed.
