Synthesis of Ag2O decorated hierarchical TiO2 templated by double comb copolymers for efficient solar water splitting

Abstract

Synthesis of Ag₂O decorated hierarchical TiO₂ was realised in this study by employing a facile hydrothermal method, which involved the use of a double comb copolymer templated sol–gel and a chemical bath. The synthesized Ag₂O@HNR demonstrated a photocurrent density of 1.78 mA cm⁻² at 1.23 V against RHE under an illumination of 1 sun. This observed value of photocurrent density exceeded that of TiO₂ nanorods by 2.18 times.
