It is still a great challenge to develop efficient semiconductive photocatalysts responding to visible light radiation. We show an efficient ZnIn₂S₄/UiO-66 hybrid photocatalysts with flowerlike 3D microspheres synthesized via a facile solvothermal method. A 20 wt.% UiO-66 emersion raises the Cr(VI) reduction rate up to 99% and higher after 60 min visible light irradiation. The substantial enhancement of photocatalytic and photoelectronchemical activity of pure ZnIn₂S₄ by UiO-66 addition is attributed to the ZnIn₂S₄/UiO-66 interfacial charge transferring and more active sites for pollute adsorption.

UiO-66与ZnIn ₂ S ₄花状3D微球之间的有效电荷分离具有光电子化学性质

开发响应可见光辐射的高效半导体光催化剂仍然是一个巨大的挑战。我们展示了一种高效的ZnIn ₂ S ₄ / UiO-66杂化光催化剂，其具有通过简易溶剂热法合成的花状3D微球。在60分钟可见光照射后，UiO-66的20％（重量）冒出率会使Cr（VI）的还原率提高到99％或更高。通过添加UiO-66可以大大提高纯ZnIn ₂ S ₄的光催化和光电化学活性，这归因于ZnIn ₂ S ₄ / UiO-66界面电荷转移和更多的污染吸附活性位。
