Fig. 4

a PE (1.59 g, ~112 mmol of carbon) depolymerization under solvent-free condition: catalyst (0.2 g, metal loading = 2.5 wt%), 45 bar H2, 375 °C, 2 h via ZSM-5_H, b Ru/ZSM-5_H, c Co/ZSM-5_H, d Ni/ZSM-5_H, e Co/ZSM-5_H, reaction time = 16 h, f Ni/ZSM-5_H, reaction time = 16 h. g PE (0.2 g, ~14 mmol of carbon) depolymerization under the solvent-assisted condition: nC16 (1.4 g, ~98 mmol based on carbon, as a reactive solvent), catalyst (0.1 g, metal loading = 2.5 wt%), 45 bar H2, 375 °C, 6 h via Co/ZSM-5_H and h Ni/ZSM-5_H.
