Electronegativity-driven d-band center shifts in Ru–Ni alloys for low methane hydrogenolysis of polyolefin plastics

Key Points

• The research aims to explore how electronegativity affects d-band center shifts in Ru–Ni alloys and their efficiency in breaking bonds in plastics.
• Examined Ru–Ni alloy composition and structure.
• Conducted hydrogenolysis reactions to assess C–C bond cleavage performance.
• Measured methane formation as a byproduct in reactions.
• Ru–Ni alloys demonstrated effective C–C bond cleavage in plastic waste.
• D-band modulation significantly reduced methane production.
• Conversion of plastic waste to valuable fuels was achieved with improved selectivity.
