Smart architectures of TiO2 are attracting increasing attention due to their outstanding properties in a broad range of fields. Herein, we report the preparation of an unprecedented yolk/shell wrinkled TiO2 architecture with excellent photocatalytic activities under visible light irradiation. This method includes solvothermal, partial etching and hydrogen treatment sequential preparation steps. The solvothermal step leads to yolk@shell TiO2 (Y@S-TiO2) structures which can generate multiple reflections of incident light so as to promote an efficient light harvesting due to an enhanced surface area and light scattering ability based on the hydrothermal alkaline partial etching. The hydrogen treatment process generated Ti3+ species on the surface of TiO2 which facilitate electron–hole separation, decreasing the band gap of titania to the visible region. The resultant yolk@hydrogenated wrinkled shell TiO2 architecture exhibited high efficiency in visible light oxidation of alcohols to the corresponding aldehydes (up to 90% in conversion and 97% in selectivity).
