A well-designed C-TiO2 hybrid with high surface area (183 m2/g) and highly dispersed nano-TiO2 on carbon was prepared by a facial one-pot hydrothermal reaction using glucose as structure-directing agent and carbon source. The utilization of glucose in hydrothermal process controls the nucleation and growth of TiO2 particles, and the rota-crystallization (hydrothermal crystallization at certain rotating rate) further introduces a uniform TiO2-layer on the carbon particles. The nanosized TiO2 particles and interconnected nanopores of the C-TiO2 hybrid greatly improve the catalytic activity of Ru NPs for selective hydrogenation of benzoic acid (BA) to cyclohexane carboxylic acid in water at low temperature (as low as 50 °C), and the TOF can achieve as high as 283 h−1. Compared with static crystallization, rota-crystallization endows Ru/C-TiO2 higher surface area, easier reducibility of Ru species and higher stability of Ru/C-TiO2 for selective hydrogenation of BA.
