Sustainable and efficient hydrogen evolution over a noble metal-free WP double modified Zn_xCd_1−xS photocatalyst driven by visible-light

Abstract

In terms of energy acquisition, research on the photocatalytic cracking of water to produce hydrogen has become a hub for us to make a transition from theoretical research to practical applications.

Amorphous WP‐Modified Hierarchical ZnIn2S4 Nanoflowers with Boosting Interfacial Charge Separation for Photocatalytic H2 Evolution

“…[39] Moreover, Yan et al reported the modification of Zn x Cd 1−x S solid solution by using tungsten phosphide (WP) as a cocatalyst. The hydrogen production rate of the 25 wt%WP/Zn x Cd 1−x S composite is almost four times higher than the pure Zn x Cd 1−x S. [41] Therefore, loading metal phosphide cocatalysts have been proved to effectively enhance the charge separation and transfer efficiency, thereby enhancing the activity of photocatalytic water splitting for hydrogen production. However, they are still far from reaching the large-scale applications required for industrialization, and the research on transition metal phosphide as a cocatalyst for photocatalytic hydrogen production has yet to be developed.…”

In Situ Spatial Charge Separation of an Ir@TiO2 Multiphase Photosystem toward Highly Efficient Photocatalytic Performance of Hydrogen Production

“…For instance, various TiO 2 modifications can be obtained with different colors depending on the utilizing conditions, assigned to the presence of various states of Ti 3+ or Ti 4+ and oxygen vacancies (V O ) in the TiO 2 lattice. To improve the generation efficiency of H 2 , some noble-metal or transition-metal nanoparticle cophotocatalysts have been widely utilized in the overall water splitting process because of their unique physicochemical properties and characteristics derived from the limiting dimensions on the nanoscale. − Recently, some research groups have also demonstrated that compared with any private component of precious metals or semiconductors, , the construction of photosystems with heterojunction structures exhibits superior photocatalytic performance under visible light irradiation via the well-controlled energy band structures of semiconductors and refrains the strong hydroxyl radical intermediates prone to overoxidation, resulting in high photocatalytic behaviors. For example, Zhao et al reported that Pt-loaded, Rh-doped SrTiO 3 exhibited a remarkably high photoelectrochemical (PEC) behavior and the conversion of alcohol to efficiently form H 2 under visible light.…”

Rational design of 0D Mn0.05Cd0.95S anchored on 3D NiSe2 nanoparticles for efficient photocatalytic hydrogen production

“…As shown inFig. 5 , the all samples exhibited IV type isotherms with H3 hysteresis loops, indicating that they had mesoporous structure [42]. The S BET was augmented from 12 to 15 m 2 g -1 after loading MCS onto surface of NiSe 2 , this was because the cubic NiSe 2 provide enough space for anchoring of MCS nanoparticles, which effectively prevent the occurrence of agglomeration.…”
