Title
Photocatalytic reduction of CO2 on FeTiO3/TiO2 photocatalyst
Abstract

A uniform heterojunction photocatalyst of FeTiO3/TiO2 composite (FTC) was synthesized by a facile hydrothermal method. The structure, morphology, and spectral properties of FTC were characterized by X-ray diffraction, Raman spectroscopy, transmission electron microscopy, and UV–Vis diffuse reflectance spectroscopy. The FeTiO3 content can be easily tuned by tailoring the precursor amount. The FTC exhibits remarkable photocatalytic activity on CO2 reduction to CH3OH under both visible and UV–Vis light irradiation, presumably due to its unique band structures and the efficient charge transfer between two semiconductors as well as the low band gap of FeTiO3.

Graphical abstractThe photocatalytic reduction of CO2 has been performed on FeTiO3/TiO2 heterojunction photocatalyst under visible light irradiation. The FeTiO3 serves as electron trap providing active sites for CO2 reduction with selective production of CH3OH.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights►FeTiO3/TiO2 heterojunction photocatalyst has been synthesized. ►The catalysts are highly active for CO2 reduction under visible light irradiation. ►The junction effect of two semiconductors is responsible for the high efficiency.
