Abstract

In this investigation, we had prepared a hybrid assembly Ag/AgCl(BaCl₂)@ZnO via one pot method by introducing barium chloride to make a plasmonic Ag-loaded AgCl on ZnO. The molecular device was further modified by addition of GO. As-synthesized Ag/AgCl(BaCl₂)@ZnO hybrid and Ag/AgCl(BaCl₂)@ZnO/GO ternary nanocomposites, exhibit a noticeable photocatalytic hydrogen production rate through cleavage of water, Where photo-induced electrons transferred from Ag/AgCl@ZnO to Ag/BaCl₂@ZnO through the additional surface states (SURS) as well as metal induced gap states(MIGS) that resulted in low photo-generated charge-carrier recombination rate in Ag/AgCl(BaCl₂)@ZnO/GO ternary nanocomposite. Which, exhibited the good hydrogen production ability (292.0 μmol H₂ h⁻¹g⁻¹) over the hybrid assembly (241.5 μmol H₂ h⁻¹g⁻¹) towards the water splitting under the visible light irradiation. The X-ray powder diffraction, UV–Vis spectroscopy, FTIR, X-ray photoelectron spectroscopy (XPS), spectroflourimetry, FESEM, and EDX are used to elucidate the electronic environment of the as-synthesized samples as well as to correlate with their photocatalytic activity in terms of water splitting.

Ag/AgCl/BaCl2@ZnO/GO纳米复合材料：合成、表征及其在水裂解中的应用

在本研究中，我们采用一锅法制备了Ag/AgCl(BaCl2)@ZnO杂化组件，通过引入氯化钡在ZnO上制备了等离子体负载Ag的AgCl。通过添加氧化石墨烯对分子器件进行进一步修饰。Ag/AgCl(BaCl2)@ZnO杂化和Ag/AgCl(BaCl2)@ZnO/GO三元纳米复合材料通过水的解理表现出明显的光催化产氢速率，其中光诱导电子通过附加表面态（SURS）和金属诱导间隙态（MIGS）从Ag/AgCl@ZnO转移到Ag/BaCl2@ZnO，导致Ag/AgCl(BaCl2)@ZnO/GO三元纳米复合材料的光生电荷载流子重组率低。结果表明，在可见光照射下，杂化组合的水裂解产氢能力（292.0 μmol H2 h−1g−1）优于杂化组合（241.5 μmol H2 h−1g−1）。利用x射线粉末衍射、紫外可见光谱、FTIR、x射线光电子能谱（XPS）、荧光光谱法、FESEM和EDX分析了合成样品的电子环境，并对其光催化活性进行了分析。
