a Kinetic studies. Reaction conditions: 0.5 mmol 4-nitrophenol, 1 mL ethyl acetate, 60 mg Ni-L1@TiO2−800, 20 bar H2, 130 °C, 24 h. b, c Control experiments. Reaction conditions: (b) 0.5 mmol 4-nitrophenol, 1 mL ethanol, 60 mg Ni-L1@TiO2−800, 20 bar H2, 130 °C, 24 h. (c) 0.5 mmol 4-aminophenol, 1 mL ethyl acetate, 60 mg Ni-L1@TiO2−800, 20 bar H2, 130 °C, 17 h. In situ XPS characterization was performed at 130 °C under 1 bar N2 (d, f) and H2 (e, g) for 1 h, (d, e) Ti 2p for Co-L1@TiO2−800, (f, g) Ti 2p for Ni-L1@TiO2−800. (h) Proposed reaction pathway.
