新型可见光驱动半导体光催化剂在环境改善和太阳能转化方面的应用受到了广泛关注。在本研究中，通过简单的无添加剂水热法制备了一种新型可见光驱动的invo4光催化剂。该产品为三维球形结构，结晶良好。Pt加载在该系统中起着关键作用。粒子表面的铂纳米晶体不仅具有电荷收集器和转运体的作用，而且还能产生更多的活性位点。pt - invo4光催化剂表现出良好的可见光催化活性，在甲醇为牺牲试剂的情况下，对环丙沙星（CIP）的降解率达到98.2%，h2产率达到9.76μmolh−1g−1。
New types of visible-light-driven semiconductor photocatalysts for the applications of environmental improvement and solar energy conversion have received much attention. In this study, a novel visible-light-driven InVO4photocatalyst was successfully synthesized by a facile additive-free hydrothermal method. The product is 3D spheric structure and well-crystallized. Pt loading plays a key role in this system. Pt nanocrystals on the particle surface not only act as charge collectors and transporters but also produce much more active sites. The Pt–InVO4photocatalyst exhibited excellent visible-light-driven photocatalytic activity that reach the ciprofloxacin (CIP) degradation ratio of 98.2% and H2production rate of 9.76μmolh−1g−1with methanol as the sacrifice reagent.
