Construction of S-scheme heterojunction consisting of Zn0.5Cd0.5S with sulfur vacancies and Ni Co1-(OH)2 for highly efficient photocatalytic H2 evolution

Uniform-embeddable-distributed Ni3S2 cocatalyst inside and outside a sheet-like ZnIn2S4 photocatalyst for boosting photocatalytic hydrogen evolution

“…It could be observed that UEDNiS/ZIS displayed a higher cathodic current density than TSLNiS/ZIS and pure ZIS, indicating that UEDNiS/ZIS possessed a lower overpotential for the water-splitting reaction than TSLNiS/ZIS and ZIS. 46–48…”

[46][47][48] The nitrogen adsorption-desorption isotherms as well as pore-size distribution of UEDNiS/ZIS and TSLNiS/ZIS were acquired to study their textural properties. As seen in Fig.…”

S-scheme heterojunction AgCl/g-C3N4 with a unique electron transfer channel via a built-in electric field for enhanced H2 production

“…[58][59][60] In this S-scheme heterojunction, not only is a strong redox potential introduced to form an internal electric eld, but also draws into the same Fermi level to reduce the resistance during electron transition, meanwhile, band bending precipitates the holes in the electron depletion layer and the electrons of the electron accumulation layer at the interface area to be reunited. [61][62][63][64][65][66] The charge-transfer route in the AgCl/g-C 3 N 4 S-scheme heterojunction is shown in Fig. 7, where AgCl and g-C 3 N 4 with staggered band structures form an S-scheme heterojunction, which shows a distinctive chargetransfer trajectory with the electrons in the VB of g-C 3 N 4 transferred into the CB of AgCl.…”

Decorating Zn0.5Cd0.5S with C,N Co-Doped CoP: An Efficient Dual-Functional Photocatalyst for H2 Evolution and 2,5-Diformylfuran Oxidation

“…Moreover, the photocatalytic performance of Zn x Cd 1– x S was also restricted by the fast recombination of photogenerated charge carriers (PCCs, including e – and h + ). Decorating chalcogenides with a noble-metal-free cocatalyst is an effective strategy to improve this situation, like transition metal compounds. , Many noble-metal-free, low-cost, and content-rich Co-based materials is considered due to their high efficiencies and good stabilities, such as CoS, , CoP, − and Co­(OH) 2 . , Due to the position of the band gap, they have been widely used as cocatalysts for photocatalytic H 2 production. As partial Co-based materials have similar properties to zerovalent metals, they can efficiently transfer photogenerated e – while preventing the recombination of photoinduced e – and h + .…”
