Special Issue Information

Dear Colleagues,

In addressing the most pressing issues of the 21st century, namely environmental pollution remediation and alternative fuel production, photocatalysis represents a powerful technology to exploit light radiation to obtain strategic products for the economies of today and tomorrow. There is a wide range of possible approaches that can be pursued, either organic or inorganic pollutant oxidation for air quality remediation or solar fuel production from waste biomass or CO2-rich flue gases. Within heterogeneous photocatalysis, the most promising, yet challenging, strategy is to design materials for specific processes, the possible great potential has not yet been achieved yet.

The aim of this Special Issue is to provide insight on cutting edge photocatalytic technologies, focusing on the most important on innovative solutions for efficient photocatalytic pollutant abatement and fuel production. Photocatalysts, the key component of this technology, and process design need to be designed according to each reaction’s specific needs, finding the best way to solve them.

An effective process based on the photocatalytic reduction of CO2 to face on the one hand, the crucial problem of environmental pollution, and, on the other hand, to propose an efficient way to product clean and sustainable energy sources has been developed in this work. Particular attention has been paid to the sustainability of the process by using a green reductant (water) and TiO2 as a photocatalyst under very mild operative conditions (room temperature and atmospheric pressure). It was shown that the efficiency in carbon dioxide photoreduction is strictly related to the process parameters and to the catalyst features. In order to formulate a versatile and high performing catalyst, TiO2 was modified by oxide or metal species. Copper (in the oxide CuO form) or gold (as nanoparticles) were employed as promoting metal. Both photocatalytic activity and selectivity displayed by CuO-TiO2 and Au-TiO2 were compared, and it was found that the nature of the promoter (either Au or CuO) shifts the selectivity of the process towards two strategic products: CH4 or H2. The catalytic results were discussed in depth and correlated with the physicochemical features of the photocatalysts. Full article
