Abstract Hybrid structures of semiconductor-based photocatalysts have been developed for water remediation. One of the possible types of hybrid structures is composed of n-type semiconductors like popular ZnO and other p-type semiconductors to separate effectively electrons and holes generated by light. In this study, an n-type ZnO and p-type delafossite CuGaO2 are compounded hydrothermally. It is demonstrated that the morphological figures including particle size, aspect ratio, and specific surface area of the hybrid materials can be controlled. As a result of the photocatalytic activities, the changes caused by controlling specific surface area and morphological traits are observed as degradation speed.

通过控制粒径估计铜铁矿 p 型 CuGaO2/ZnO 杂化物作为半导体光催化剂

摘要 半导体基光催化剂的混合结构已被开发用于水修复。一种可能的混合结构类型由 n 型半导体组成，如流行的 ZnO 和其他 p 型半导体，以有效地分离由光产生的电子和空穴。在本研究中，n 型 ZnO 和 p 型金铁矿 CuGaO2 水热复合。结果表明，混合材料的粒径、纵横比和比表面积等形态特征是可以控制的。作为光催化活性的结果，通过控制比表面积和形态特征引起的变化被观察为降解速度。
