Special Issue Information

Dear Colleagues,

Photocatalytic water splitting has been considered as one of the most promising strategies for producing renewable and clean hydrogen fuel. This process involves the use of photocatalysts to convert sunlight energy into chemical energy, which could be utilized to split water into hydrogen and oxygen. Although significant progress has been made in this field over the past few decades, there are still several challenges that need to be addressed in order to achieve efficient and cost-effective photocatalysts for photocatalytic water splitting.

This Special Issue aims to bring together researchers from different fields to discuss the latest developments and challenges in photocatalytic water splitting, including the design and synthesis of new photocatalysts, the optimization of reaction conditions, the photoinduced carrier dynamics at the interfaces of photocatalysts, and the integration of photocatalytic systems into practical applications. The articles in this Special Issue will provide insights and perspectives on the future prospects of photocatalytic water splitting as a sustainable and clean energy source.

Black phosphorus (BP) has recently emerged as a versatile photocatalyst owing to its unique photophysical properties and tunable bandgap. Nonetheless, the rapid recombination of the photogenerated charges of pristine BP samples has significantly hindered its practical applications in photocatalysis. Herein, we report, for the first time, the effect of transition metal nanoparticles (Ni and Co) as co-catalysts on the photocatalytic activity of BP/tungsten disulfide (WS2) binary heterojunctions (BP/WS2-TM (TM: Ni, Co)) in the hydrogen evolution reaction (HER) under visible light irradiation (λ > 420 nm). Ternary heterojunctions named BP/WS2-TM (TM: Ni, Co) were synthesized via a chemical reduction method, leading to the formation of an S-scheme heterojunction, in which BP acts as a reduction catalyst and WS2 serves as an oxidation catalyst. BP/WS2-Ni and BP/WS2-Co performed substantial amounts of hydrogen generation of 9.53 mmol h−1g−1 and 12.13 mmol h−1g−1, respectively. Moreover, BP/WS2-Co exhibited about 5 and 15 times higher photocatalytic activity compared to the binary BP/WS2 heterojunctions and pristine BP, respectively. The enhanced photocatalytic activity of the heterojunction catalysts is attributed to the extended light absorption ability, enhanced charge separation, and larger active sites. This study is the first example of photocatalytic hydrogen evolution from water by using Ni- and Co-doped binary BP/WS2 heterojunctions. Full article
