Fig. 3: The catalytic performance of the dilute Ru9Pt91 alloy toward PE hydrogenolysis.

From: Polyethylene hydrogenolysis by dilute RuPt alloy to achieve H2-pressure-independent low methane selectivity

Fig. 3

a–c Time courses of PE hydrogenolysis over Ru9Pt91/C (a), Pt/C (b) and Ru/C (c), where the product yields are presented in mass percentage. More detailed carbon distributions are presented in Supplementary Fig. 7. Reaction conditions: 0.5 MPa H2, 300 °C, 340 mg PE, 20 mg catalyst. d The effects of Ru content in RuPt alloy on the methane selectivity at a H2 consumption around 1.75 mmol under 0.5 MPa H2. e Methane selectivity for PE hydrogenolysis under different hydrogen pressures catalyzed by Ru9Pt91/C and Ru/C at H2 consumption around 1.75 mmol. f PE hydrogenolysis over Ru9Pt91/C, Ru14Ni86/C, Ru6Co94/C, and Ru9Pd91/C. Reaction conditions: 0.5 MPa H2, 300 °C, 340 mg PE, 0.5 mg Ru, 8 h. The error bars represent the standard deviations of three independent measurements.
