Abstract

A tri-stable switchable catalyst is encoded by pH-controlled dynamic self-assembly of gold and TiO nanoparticles (NPs). Through precise adjustment of the integrated dynamic covalent and noncovalent self-assembly process of the two types of nanoparticles, the photocatalytic activity of the hybrid system is modulated by switching pH conditions between tri-stable "highly active", "active", and "inactive" states.

摘要

一种三稳态可切换催化剂由金和 TiO 纳米粒子(NPs)的 pH 控制动态自组装编码。通过精确调节两种类型的纳米粒子的集成动态共价和非共价自组装过程,通过在三稳态“高活性”、“活性”和“非活性”状态之间切换 pH 条件来调节杂化系统的光催化活性。
