From: Catalytic refining lignin into toluene over atomically dispersed Cu/Ni dual sites
Reaction conditions: substrates (0.5 mmol), catalyst (20 mg with a total amount of metals at ca. 0.01 mmol), 1,4-dioxane (4 mL), 180 °C, 12 h, H2 (0.5 MPa). [b] 200 °C, H2 (1 MPa). [c] 260 °C, n-hexane (4 mL), H2 (2 MPa). Taking 1a and 12 d as two examples, typical GC spectra and detailed calculation procedures are provided in Supplementary Figs. 18-19.
