- This work describes a new pathway of hydrogen energy production through annealing of titanium oxide (anatase) under hydrogen. The treatment introduces additional defects to the anatase lattice, modifying its optical absorption, changing its colour to black. The annealed samples showed a noticeable improvement in photocatalytic activity under visible light and an improved photoelectrochemical response. The experimental findings and supporting theoretical calculations are important because they advance understanding of the role of hydrogen in modification of the structural and electronic properties of TiO2 to realize improvements in photocatalytic properties. This work resulted in Industry academia grant funded by RAENG.
