Advanced Materials, Год журнала: 2023, Номер 36(8)

Опубликована: Ноя. 22, 2023

Abstract Semiconductor photocatalytic technology holds immense promise for converting sustainable solar energy into chemically storable energy, with significant applications in the realms of and environment. However, inherent issue rapid recombination photogenerated electrons holes hinders performance single photocatalysts. To overcome this challenge, construction 2D S‐scheme heterojunction photocatalysts emerges as an effective strategy. The deliberate design dimensionality ensures a substantial interfacial area; while, charge transfer mechanism facilitates efficient separation maximizes redox capabilities. This review commences fresh perspective on heterojunctions, followed by comprehensive exploration preparation methods characterization techniques. Subsequently, recent advancements are summarized. Notably, behind activity enhancement is elucidated. Finally, prospects development presented.

Construction of Interfacial Electric Field via Dual‐Porphyrin Heterostructure Boosting Photocatalytic Hydrogen Evolution

Advanced Materials, Год журнала: 2021, Номер 34(3)

Опубликована: Ноя. 5, 2021

A dual-porphyrin heterostructure is successfully constructed by coupling tetrakis (4-carboxyphenyl) zinc porphyrin (ZnTCPP) with (4-hydroxyphenyl) (THPP). The high photocatalytic H2 evolution rate of 41.4 mmol h-1 g-1 obtained for ZnTCPP/THPP under full spectrum, which ≈5.1 and ≈17.0 times higher than that pure ZnTCPP THPP, respectively. significantly enhanced activity mainly attributed to the giant interfacial electric field formed between dual porphyrins, greatly facilitates efficient charge separation transfer. Meanwhile, similar conjugated structures porphyrins also provide proper interface match decrease defects, thus inhibiting recombination photoproduced carriers. By rationally combining appropriate band high-quality contact this work provides a fresh insight into construction improve performance.
