Abstract

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/g_catalyst was produced at 5mg_{N − ZIS}/35ml_{reaction 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.

N掺杂增强Znln2S4上太阳能光催化水裂解反应

太阳能驱动的光催化水制氢在实现脱碳中起着关键作用。选择高效稳定的光催化剂是决定水分解效率的关键因素之一。近年来，基于ZnIn2S4 （ZIS）的光催化剂因其具有带隙小、光捕获能力强、毒性小、易于制备等优点而受到广泛关注。因此，本研究首先合成了原始ZIS和n掺杂ZIS （N-ZIS）光催化剂，然后研究了不同反应条件（如光催化剂浓度、牺牲剂种类和用量）下的水裂解反应。随后，对光催化剂和牺牲剂的稳定性进行了探讨。结果表明，N掺杂促进了总气体在水裂解反应中的析出。反应介质为5mgN−ZIS/35ml，甲醇为牺牲剂，加入15 vol%的甲醇，反应时间为2 h时，催化剂总气量最大，为17559µmol/g。在N-ZIS和甲醇的稳定性研究中，在第3循环时，N-ZIS和甲醇的稳定性分别下降了6.67%和29.03%。总的来说，本研究为zis基光催化剂在N掺杂技术上的光催化水分解提供了新的见解和知识。图形抽象

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.
