Hydrogen production using mesoporous titanium dioxide
Source abstract
Abstract
Mesoporous C/N doped TiO2 (MCNT) samples were prepared, and Pt was deposited on their surfaces. The hydrogen production capability of this material was investigated by irradiating it with UV light at two different wavelengths. It was found that MCNT could be used to produce hydrogen gas. The highest hydrogen production rate was obtained when 0·003 mol Pt was deposited on the surface of 1 mol MCNT. Since this optimal Pt concentration is the same as that for P-25, it was concluded that the mesopore surface was not directly deposited with Pt. More hydrogen was produced when Pt deposited MCNT was irradiated with 350 nm wavelength UV light than with 370 nm wavelength UV light at similar intensity. This implies that the wavelength of UV light strongly affects hydrogen production.
