In all cases, H yield increases linearly with absorbed dose. Under the irradiation it was observed that with the increasing number of titanium dioxide deposition cycle a decrease in dihydrogen production were observed. A faster decrease in dihydrogen production was observed with a very small amount of titanium dioxide deposition i.e with an average thickness of 0.1 nm as measured by XPS. The productions of H were found to be decreased almost by 50 % with a TiO thickness at around 1 nm.
