Heterojunction Engineering of Multinary Metal Sulfide‐Based Photocatalysts for Efficient Photocatalytic Hydrogen Evolution

Advanced Materials, Год журнала: 2023, Номер 36(11)

Опубликована: Дек. 2, 2023

Photocatalytic hydrogen evolution (PHE) via water splitting using semiconductor photocatalysts is an effective path to solve the current energy crisis and environmental pollution. Heterojunction photocatalysts, containing two or more semiconductors, exhibit better PHE rates than those with only one owing altered band alignment at interface stronger driving force for charge separation. Traditional binary metal sulfide (BMS)-based heterojunction such as CdS, MoS

Metal-sulfide nanostructures have piqued the interest of researchers for decades due to their intriguing optoelectronic properties. Indeed, significant advances and improvements been made in various fundamental aspects cutting-edge applications, such as water splitting hydrogen production. Furthermore, rising demand low-dimensional materials lower material consumption improved performance quantum size effects has spurred research on semiconducting metal sulfides. Consequently, size-controllable with diverse morphologies fabricated studied potential applications. However, photocatalytic evolution rate is still limited mainly by fast recombination rate, poor solar energy utilization lack surface-active sites H2 reduction. This review will highlight particularly recent findings metal-sulfide-based photocatalysts reactions, considering swift development excellent this field. Following a brief overview properties, we explore state-of-the-art strategies enhancing generation efficiencies over pristine, heterostructured co-catalayzed metal-sulfide photocatalysts.

Exposed Zinc Sites on Hybrid ZnIn₂S₄@CdS Nanocages for Efficient Regioselective Photocatalytic Epoxide Alcoholysis

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(22)

Опубликована: Март 29, 2023

Photocatalytic epoxide alcoholysis through C-O bond cleavage and formation has emerged as an alternative to synthesizing anti-tumoral pharmaceuticals fine chemicals. However, the lack of crucial evidence interpret interaction between reactants photocatalyst surface makes it challenging for photocatalytic with both high activity regioselectivity. In this work, we report hierarchical ZnIn2 S4 @CdS regioselectivity nearly 100 %. Mechanistic studies unveil that precise activation switch on exposed Zn acid sites polarization a critical significance achieving efficient performance. Furthermore, establishment Z-scheme heterojunction facilitates interface charge separation transfer. Remarkably, underlying regioselective reaction pathway been distinctly revealed.
