Nanocatalyst based on nickel recovered from spent Ni-MH batteries and aluminium foil residues converts CO2 into valuable methane

"could provide around 16% of nickel needed by 2030, but even greater impact can be achieved by upcycling nickel together with upcycling alumina from used aluminium foil into high-performance nanocatalyst in an eco-friendly way... nanocatalyst consists of 92-96% aluminium oxide and 4-8% nickel, optimal for converting CO2 together with hydrogen into methane at atmospheric pressure and an easily achievable temperature of 250°C"
