摘要
在金银花提取物的辅助下，利用水热法制备了具有双 Z 型结构的新型 Bi 复合光催化剂 BiVO4/g-C3N4/Ag3PO4。当复合材料中 Ag3PO4 的质量分数为 10%时，对大肠杆菌和金黄色葡萄球菌的灭活率分别为 6.9 和 4.6 log。MIC 结果分别为 0.6 和 0.8 mg/ml。捕获实验证实，h+ 和 O2- 是催化抑菌的主要活性物质。双 Z 异质结减少了 Ag3PO4 的光化学腐蚀，改变了光生电子的传输路径，进而促进了光生电子空穴的分离，从而获得了显著的光催化活性。
Construction of BiVO4/g-C3N4/Ag3PO4 ternary heterojunction with double Z-scheme and its photocatalytic and bacteriostatic properties
A novel Bi-composite photocatalyst BiVO4/g-C3N4/Ag3PO4 with a double Z-scheme structure was prepared by hydrothermal method assisted by honeysuckle extract. When the mass fraction of Ag3PO4 in the composite is 10 %, the inactivation rates of E.coli and S. aureus were 6.9 and 4.6 log, respectively. The MIC results were 0.6 and 0.8 mg/ml, respectively. The capture experiment confirmed that h+ and O2− were the main active substances that catalyzed bacteriostasis. Double Z heterojunction reduces the photochemical corrosion of Ag3PO4, changes the transmission path of photogenerated electrons, and then promotes the separation of photogenerated electron holes, thus obtaining significant photocatalytic activity.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
