Herein, Ni@C/TiO2-Z catalyst was prepared by in-situ hydrothermal synthesis, which has better catalytic effect than the commercially available TiO2 supported by Ni@C. And Ni@C more evenly dispersed. Ni@C/TiO2-Z can catalyze the oxidation of a variety of aromatic alcohols to produce aldehydes or acids, and the catalytic activity did not decrease after 4 cycles of experiments. Choosing different solvents could adjust the products, such as aromatic aldehydes or aromatic acids. This provides a theoretical basis for the industrial utilization of photocatalytic alcohol oxidation to produce aldehydes or acids in the future.
