Effective combination of metal-support for bimetallic catalysts system in ethanol and glycerol reforming: A review

The reliance on fossil fuels to meet the world energy demands throughout these years has led to future insecurity of non-renewable energy sources. Thus, the necessity to provide the energy requirement as we are moving forward falls into renewable and environmentally friendly options. Syngas or hydro...
