TiO2/Ga2O3复合光催化胶体的制备方法
摘要：
本发明公开了一种TiO2/Ga2O3复合光催化胶体的制备方法，包括以下步骤：1）合成TiO2溶胶 2）合成Ga2O3溶胶 3）TiO2/Ga2O3复合光催化胶体合成：将步骤1）和步骤2）所制备的TiO2胶体和Ga2O3胶体按9～999:1的重量比例混合，持续搅拌2～6小时；最终TiO2/Ga2O3复合胶体中Ga2O3含量控制在0.1‑5.0 wt%即可；本发明太阳光利用率高以及催化氧化能力强。
摘要（英）：

The invention discloses a preparation method of a TiO2/Ga2O3 composite photo-catalytic colloid. The method comprises the following steps: (1) synthesizing TiO2 sol; (2) synthesizing Ga2O3 sol; (3) synthesizing the TiO2/Ga2O3 composite photo-catalytic colloid by mixing the TiO2 sol prepared in the step (1) with the Ga2O3 sol prepared in the step (2) according to a weight ratio of (9-999) to 1, continuing to stir for 2-6 hours, and finally controlling the content of Ga2O3 in the TiO2/Ga2O3 composite colloid to be 0.1-5.0wt%. The TiO2/Ga2O3 composite photo-catalytic colloid prepared by the method is high in sunlight utilization rate and catalytic oxidation capability.
