Reduced {001}-TiO2-x photocatalysts: noble-metal-free CO2 photoreduction for selective CH4 evolution.

Abstract

The preparation of reduced TiO2 photocatalysts with high Ti3+ concentration is a great challenge due to their instability in air. Here we report a new approach for the synthesis of reduced TiO2 with {001} facets exposed via a hydrothermal process. By the introduction of fluoride atoms, {001} and {101} facets are formed, which act as hole and electron… (More)
