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

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.
