Enhancing Solar Energy-Driven Photocatalytic Water Splitting Reaction Over Znln2S4 by N Doping
The solar energy-driven photocatalytic H2 production from water plays a critical role in achieving decarbonization. One of the key factors determining the water splitting efficiency is the selection of highly effective and stable photocatalysts. Recently, ZnIn2S4 (ZIS) based photocatalysts have attracted a great deal of attention due to smaller bandgaps, great light harvesting ability, less toxicity, and ease of fabrication. Therefore, in this study, pristine ZIS and N-doped ZIS (N-ZIS) photocatalysts were synthesized, followed by the investigation of the water splitting reaction under different reaction conditions (e.g., photocatalyst concentration and type and dosage of sacrificial agent). Afterward, the stability of the photocatalyst and sacrificial agent was explored. The results showed that N doping enhanced the evolution of total gases via water splitting reaction. The maximum amount of total gases of 17,559 µmol/gcatalyst was produced at 5mgN − ZIS/35mlreaction medium, methanol as the sacrificial agent, 15 vol% methanol addition for 2 h reaction time. In the stability study of N-ZIS and methanol, a decrease of 6.67% and 29.03% was observed at 3rd cycle, respectively. Overall, the present work provides new insights and knowledge into photocatalytic water splitting over N doping technique for ZIS-based photocatalysts.
期刊介绍：
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
