本文设计并实现了（CuC10N26N6）(3)(PW12O40)(2)/AgCl@Ag的z型光催化剂，可在模拟阳光下有效去除可溶解和不可溶解的持久性有机污染物和析氢。采用简单的水热化学共沉淀法合成了催化剂。在模拟阳光下，对持久性污染物2,4-二硝基苯酚（DNP）和四环素（TC）具有良好的光催化降解能力，h -2产率高达19.28 μ mol g(-1) h（-1）。通过结构、形态、自由基和电化学的测定，研究了光催化机理，并将其归因于（CuC10H26N6）(3)(PW12O40)(2)和AgCl@Ag异质结对偶物之间有效的载电子分离。(C) 2019 Elsevier Inc.版权所有。
In this work, Z-scheme photocatalysts of (CuC10N26N6)(3)(PW12O40)(2)/AgCl@Ag were designed and realized for effective removal of solvable and insolvable persistent organic pollutants and hydrogen evolution under simulated sunlight. The catalysts were synthesized via a simple hydrothermal-chemical co precipitation method. Excellent photocatalytic abilities are demonstrated in degradations of persistent pollutant 2,4-Dinitrophenol (DNP) and tetracycline (TC) under simulated sunlight, as well as a high H-2 production rate of 19.28 mu mol g(-1) h(-1). Through structural, morphological, radical, and electrochemical determinations, the photocatalytic mechanism was studied, and attributed to effective separations of charge carriers between the heterojunctional counterparts of (CuC10H26N6)(3)(PW12O40)(2) and AgCl@Ag.
