a Reaction pathway and time-dependent product distribution of PHO reaction over b Ru/C and c Pd/C-O; d Catalytic performance of various catalysts in PHO reaction; e recycled performance of Pd/C-O in PHO reactions; f catalytic performance of various catalysts in 4,4’-dimethyl diphenyl ether reaction. Reaction conditions: methanol (15 mL), temperature (110 °C), H2 (2.0 MPa), b PHO (0.09 mmol), Ru/C (2 mg), c Pd/C-O (20 mg), PHO (0.09 mmol), d PHO (0.09 mmol), time (12 h), Ru/C (2 mg), Pd/C (20 mg), or Pd/C-O (20 mg); e PHO (0.09 mmol), Pd/C-O (20 mg), time (1 h). f 4,4’-Dimethyl diphenyl ether (0.09 mmol), Ru/C (5 mg), Pd/C (50 mg), Pd/C-O (50 mg), time (12 h). The products were quantified by GC.
