AbstractThe world’s current energy demands and foreseeing projections of growing demands in upcoming years have promoted the development of pollution-free alternative sources of energy. As recently stated in the United Nations Climate Conference in Paris, the necessity of achieving energy efficient and environmental friendly processes to limit the climate change appears crucial. Within this context, sustainable and green chemical processes are an imperative for the future, thus sustained catalytic performance, with high selectivity, coupled to environmental consideration is an important and strategic focus. Hydrogen obtained from fossil fuels (hydrocarbons and other organic molecules) has been used since the early days in catalysis, but the use of renewable sources as a primary target for hydrogen production would make this molecule a versatile energy carrier, and mitigate impact of pollutants. Significant advancement in catalytic technologies related to the water–gas shift, steam reforming, partial oxidation, autothermal reforming, supercritical water reforming, CO2-sorption-assisted and thermochemical looping processes have shown potential and interesting results. Some of the above mentioned processes as well as hybrid technologies used in combination have been studied intensively, but they have drawn renewed attention due to the refocus on the use of more naturally abundant resources, challenging demands on catalytic conditions and, particularly, on the use of oxygenated molecules as primary reactants. Moreover, the combination with light as an energy source and activator of chemical process has shown potential in almost all the above mentioned reactions and certainly is a way for a greener future.
