The conversion of greenhouse gases (especially CH4 and CO2) to value-added chemicals is of great importance in the context of climate change as well as the chemical industry. Due to the harsh conditions of the traditional conversion methods of CH4 and CO2 in industry and the use of expensive and polluting metal surfaces, finding a clean catalyst with high selectivity to directly synthesize fuels from CH4 and CO2 gases at room temperature would thus be very beneficial from a chemical, environmental and economic perspective. My research concerns the computationally development of new nanocatalysts by means of density functional theory (DFT) calculations to investigate the atomistic details of the gas conversion reaction mechanisms on those novel nanocatalysts like graphene and carbon nanotube.
