Black N/H-TiO2 nanoplates with a flower-like hierarchical architecture for photocatalytic hydrogen evolution
Black N/H-TiO2 nanoplates with a flower-like hierarchical architecture for photocatalytic hydrogen evolution
Solar-energy-driven water splitting represents one of the most sustainable and clean hydrogen sources for fuel cells and storage of intermittent solar energy. The paper reported a facile two-step strategy to manufacturing black hydrogenated/nitrogen-doped TiO2 nano-plates with flower-like architecture which displayed enhanced hydrogen evolution in photocatalytic water splitting under AM 1.5 illumination using solar simulator. The strategy includes in-situ nitriding and self-assembly by hydrothermal synthesis using tripolycyanamide as N source and structure-directing agent prior to further hydrogenation at mild temperature. With thorough characterisations, the improved hydrogen evolution was attributed to a reduced bandgap, enhanced separation of the photogenerated charge carriers and increased surface-active sites.

Abstract
Solar-energy-driven water splitting represents one of the most sustainable and clean hydrogen sources for fuel cells and storage of intermittent solar energy. The paper reported a facile two-step strategy to manufacturing black hydrogenated/nitrogen-doped TiO2 nano-plates with flower-like architecture which displayed enhanced hydrogen evolution in photocatalytic water splitting under AM 1.5 illumination using solar simulator. The strategy includes in-situ nitriding and self-assembly by hydrothermal synthesis using tripolycyanamide as N source and structure-directing agent prior to further hydrogenation at mild temperature. With thorough characterisations, the improved hydrogen evolution was attributed to a reduced bandgap, enhanced separation of the photogenerated charge carriers and increased surface-active sites.
