Methane in shale gas can be turned into hydrocarbon fuels using an innovative platinum and copper alloy catalyst, according to new research led by University College London (UCL) and Tufts University.
Platinum or nickel are known to break the carbon-hydrogen bonds in methane found in shale gas to make hydrocarbon fuels and other useful chemicals. However, this process causes ‘coking’ – the metal becomes coated with a carbon layer rendering it ineffective by blocking reactions from happening at the surface.
The new alloy catalyst is resistant to coking, so it retains its activity and requires less energy to break the bonds than other materials. Currently, methane reforming processes are extremely energy intense, requiring temperatures of about 900 degrees Celsius. This new material could lower this to 400 degrees Celsius, saving energy.
The study published in the journal Nature Chemistry, demonstrates the benefits of the new highly diluted alloy of platinum in copper – a single atom alloy – in making useful chemicals from small hydrocarbons.
