Abstract Novel g-C3N4-Bi2MoO6-Ag nanocomposite with their g-C3N4 nanosheets were synthesized by a facile hydrothermal method. The superior photocatalytic performance of gC3N4-Bi2MoO6-Ag nanocomposite was owing to the interface of Bi2MoO6/Ag nanomaterials whereas reduced the bandgap which enables high separation efficiency, suppressed recombination rate of charge carriers and their high specific surface area (97.4 cm3 g−1). For the MB dye degradation efficiency accomplishes 99.6% within 80 min under the visible light. Significantly, the ideal photocatalytic activity of gC3N4-Bi2MoO6-Ag composite has 3.63 times faster than pristine g-C3N4. Based on the trapping test, the superoxide radical O2•- and hydroxyl radical (OHrad) plays a vital role in dye degradation in chief g-C3N4-Bi2MoO6-Ag nanocomposite under the visible light exposure. Novel gC3N4-Bi2MoO6-Ag catalyst has been exhibited superior electrochemical performance, which is smaller charge transfer resistance (impedance), and the prime photocurrent response has confirmed that more charge carrier abilities. The physicochemical assemblies and high degradation efficiencies were preserved after five successive cycles, whereas signifying that the sample was displayed good stability. Based on the consistent energy band positions, the probable mechanism for heightening photocatalytic activity was proposed. This study delivers a visible light driven novel g-C3N4-Bi2MoO6-Ag photocatalyst is a capable aspirant material and applicable for environmental remediation. Also, the antibacterial activity is well exposed towards disinfection of the bacterial strain, including pathogens which are S. aureus (G+) and E. coli (G−) bacteria’s.

摘要 通过简便的水热法合成了新型 g-C3N4-Bi2MoO6-Ag 纳米复合材料及其 g-C3N4 纳米片。gC3N4-Bi2MoO6-Ag 纳米复合材料优异的光催化性能归功于 Bi2MoO6/Ag 纳米材料的界面，同时降低了带隙，从而实现了高分离效率，抑制了电荷载流子的复合率及其高比表面积（97.4 cm3 g-1） . MB染料在可见光下80分钟内降解效率达到99.6%。值得注意的是，gC3N4-Bi2MoO6-Ag 复合材料的理想光催化活性比原始 g-C3N4 快 3.63 倍。捕获实验表明，超氧自由基O2•-和羟基自由基(OHrad)在可见光照射下对主要g-C3N4-Bi2MoO6-Ag纳米复合材料的染料降解起着至关重要的作用。新型 gC3N4-Bi2MoO6-Ag 催化剂表现出优异的电化学性能，即较小的电荷转移电阻（阻抗），主要的光电流响应证实了更多的电荷载流子能力。在连续五个循环后保持物理化学组装和高降解效率，这表明样品显示出良好的稳定性。基于一致的能带位置，提出了提高光催化活性的可能机制。这项研究提供了一种可见光驱动的新型 g-C3N4-Bi2MoO6-Ag 光催化剂，它是一种有能力的有抱负的材料，适用于环境修复。此外，抗菌活性很好地暴露于细菌菌株的消毒，包括病原体金黄色葡萄球菌 (G+) 和大肠杆菌 (G-) 细菌。
