Hydrogen generation using nitrogen-doped TiO2 mesoporous beads/cobalt-phosphate nanocomposites

Abstract

This study has been focused on the development of the photoelectrochemical activity of nitrogen-doped TiO2 mesoporous beads/cobalt-phosphate (CoPi) nanocomposites Doping of nitrogen have been done simultaneously by facile and efficient method microwave-assisted hydrothermal (MAH) The amount of nitrogen-doped was controlled by the addition of each precursor with different ratio molar Later N-doped TiO2 mesoporous beads was mixed with CoPi to reduce its bandgap of TiO2 mesoporous beads and for catalysts the photoelectrochemical reaction in the system Mesoporous TiO2 beads were prepared over two steps including sol-gel and hydrothermal processes The morphology and its composition of the resulting beads powder were examined using scanning electron microscope (SEM) and X-Ray Photoelectron Spectroscopy (XPS) The optical properties of the nanocomposites were observed by UV-Visible spectroscopy Finally the resulted photoanode were eveluated using photoelectrochemical cell system
