a Catalytic performance of various catalysts; PHO hydrogenation kinetic experiments over Ru/C and Pd/C-O under b different PHO concentrations and c H2 pressure; d catalytic performance of PHO reaction over various catalysts under different atmosphere; e HD generation signals over Pd/C and Pd/C-O; f PHO hydrogenation rate over Pd/C and Pd/C-O. Reaction conditions: Ru/C (2 mg), Pd/C (20 mg), Pd/C-O (20 mg), methanol (15 mL), temperature (110 °C), a PHO (0.09 mmol), H2 (2.0 MPa), time (6 h); b PHO (0.09, 0.105, 0.12, 0.135 mmol), H2 (2.0 MPa), time (0.5 h); c H2 (0.5, 1.0, 1.5, 2.0 MPa), PHO (0.09 mmol), time (0.5 h); d PHO (0.09 mmol), H2 or D2 (2.0 MPa), time (0.5 h); f PHO (0.09 mmol), H2 (2.0 MPa), time (0.5 h). The products were quantified by GC.
