Mesoporous TiO anatase films for enhanced photocatalytic activity under UV and visible light.

Mesoporous TiO films with enhanced photocatalytic activity in both UV and visible wavelength ranges were developed through a non-conventional atomic layer deposition (ALD) process at room temperature. Deposition at such a low temperature promotes the accumulation of by-products in the amorphous TiO films, caused by the incomplete hydrolysis of the TiCl precursor. The additional thermal annealing induces the fast recrystallisation of amorphous films, as well as an acidic treatment of TiO.

Nanoporous materials as new engineered catalysts for the synthesis of green fuels.

This review summarizes the importance of nanoporous materials and their fascinating structural properties with respect to the catalytic and photocatalytic reduction of CO2 to methane, toward achieving a sustainable energy supply. The importance of catalysis as a bridge step for advanced energy systems and the associated environmental issues are stressed. A deep understanding of the fundamentals of these nanoporous solids is necessary to improve the design and efficiency of CO2 methanation.
