Material for improving photocatalytic oxygen production activity and stability of Ag3PO4 and preparation method thereof

The invention discloses a material for improving photocatalytic oxygen production activity and stability of Ag3PO4 and a preparation method of the material. The Ag3PO4 nano material, namely Al-BDC-NH2 and Ag3PO4 compounded heterojunction product Ag3PO4/Al-BDC-NH2, is obtained by in-situ confinement growth on Al-BDC-NH2 MOF by using the characteristic that metal silver ions are easy to coordinate with amino contained in an organic ligand of a metal organic framework material, so that the activity and stability of a traditional silver phosphate material for photocatalytic cracking of water to produce oxygen are improved. The preparation method is simple, the reaction raw materials are wide in source, experimental steps are easy to operate, universality and potential design and research value are achieved, and batch production can be achieved. 本发明公开了一种提高Ag3PO4光催化产氧活性和稳定性的材料及其制备方法。利用金属银离子易于与金属有机骨架材料有机配体中含有的氨基配位的特性，于Al-BDC-NH2MOF上原位限域生长得到了Ag3PO4纳米材料，即Al-BDC-NH2和Ag3PO4复合的异质结产物Ag3PO4/Al-BDC-NH2，提高了传统磷酸银材料光催化裂解水产氧的活性
