Hydrothermal Synthesis of Titanium Oxide Nanotube Catalysts and Its Modification for Water Splitting Application

Abstract

In this study, a hydrothermal method was used to prepare Titanium Oxide nanotube photocatalysts for splitting water into hydrogen [1,2]. Optimizing the hydrogen production efficiency of the TiO2 nanotubes by varying sodium hydroxide concentration and copper content enhances its photocatalytic reactivity. The TiO2 nanotubes impregnated with Cu followed by transfers the photoexcited electrons to the loaded metal particles and decreases electronic-electronic hole recombination. The structural information of the TiO2 nanotubes has been investigated by XRD. FE-SEM, and TEM in order to understand its chemical and physical properties. To test the reactivity of catalysts, a self-assemble reactor equipped with GC-TCD is used to analyze the water splitting efficiency.
