April 2017 - 30 articles

Cover Story: The increasing demand for highly efficient, visible-light-active photocatalysts can be addressed by TiO2-based hybrid nanostructured materials combining together two or more units, each bringing its own peculiar characteristics, surface chemistry and morphology, into one nano-object with unprecedented chemical and physical properties. Modern material science allows to suitably tailoring size, shape, crystalline phase and properly engineering surface chemistry of these hybrid nano-architectures to enhance their photocatalytic performances. Such hybrid nanocatalysts have demonstrated very promising for environmental applications including water remediation, abatement of atmospheric pollutants (NOx and volatile organic compounds (VOCs)) and self-cleaning surfaces.
