In situ decorated Ni₂P nanocrystal co-catalysts on g-C₃N₄ for efficient and stable photocatalytic hydrogen evolution via a facile co-heating method

Abstract

A Ni2P/g-C3N4 hybrid photocatalyst were in situ fabricated via a one-step co-heating solution approach. The integrated photocatalyst demonstrated extraordinary H2 evolution and excellent durability due to the unique Ni(δ+)–N(δ−) chemical bonding.

Recent Progress of Transition Metal Phosphides for Photocatalytic Hydrogen Evolution

“…Ni 2 P, a commonly used co‐catalyst, has been studied by many researchers to modify g‐C 3 N 4 for photocatalytic H 2 generation [108–110] . For example, Wen et al [108] .…”

“…Ni 2 P, a commonly used co-catalyst, has been studied by many researchers to modify g-C 3 N 4 for photocatalytic H 2 generation. [108][109][110] For example, Wen et al [108] adopted a convenient and simple strategy to obtain Ni 2 P/g-C 3 N 4 composites by co-heating Ni precursors, TOP, and g-C 3 N 4 in oleylamine (OAm). Compared with gas-solid reaction and physical self-assembly methods, Ni 2 P/g-C 3 N 4 synthesized through this method possessed better stability and photocatalytic activity due to the formation of chemical bond.…”

Integrating Covalent Organic Framework with Transition Metal Phosphide for Noble‐Metal‐Free Visible‐Light‐Driven Photocatalytic H2 Evolution

“…[25][26][27][28] Among different types of non-noble metal co-catalysts, the transition metal phosphides have the advantages of rich resources, abundant active sites, excellent charge transfer, and tunable structure, and have also been proved to be a kind of potential non-noble metal co-catalysts. [29][30][31][32] They have usually been used to be integrated with traditional inorganic semiconductor materials to construct noble-metal free photocatalysts. However, the combination of COFs and transition metal phosphides and investigation of the influence of transition metal phosphides on the charge transfer and photocatalytic water splitting properties for COFs have never been reported.…”

CsPbBr₃ perovskite nanocrystal/S doping g-C₃N₄ ultra-thin nanosheet heterojunction with enhanced interfacial charge transfer for photocatalytic CO₂ reduction

“…As a polymeric photocatalyst composed of earth-abundant elements, graphitic carbon nitride (g-C3N4) with nontoxicity, excellent physical/chemical stability, appropriate energy band, and low cost has emerged as a rather promising candidate for photocatalytic degradation [13][14][15], photocatalytic H2 evolution [16][17][18][19], photocatalytic CO2 reduction [20][21][22] and so on. However, due to the rapid recombination and the low mobility of photogenerated charge carriers, relatively narrow visible light responsive region, and the small specific surface area, the photocatalytic performance of bulk g-C3N4 with highly stacked layers is not ideal [23].…”
