Abstract

In a microreactor with colliding jets using solutions of titanium tetraisopropylate and water in isopropyl alcohol, a number of titanium dioxide powders are obtained. It is shown that an additional heat treatment of samples up to 350°C for 30 min is sufficient for the formation of the anatase phase. The developed method allows synthesis in a short time, provides low energy consumption, does not require labor-intensive operations, and is technological and easily scalable.

碰撞射流微反应器合成基于二氧化钛的光催化剂

摘要

在使用四异丙醇钛和水在异丙醇中的溶液的具有碰撞射流的微反应器中，获得了许多二氧化钛粉末。结果表明，对样品进行高达350°C的30分钟的额外热处理足以形成锐钛矿相。所开发的方法可以在短时间内进行合成，能耗低，不需要劳动密集型操作，并且技术含量高且易于扩展。
