Acceleration of Ammonium Phosphate Hydrolysis Process via TiO2 Microspheres as A Catalyst for Hydrogen Production

Titania microspheres assess as an adequate material with low cost, and ease attainable pathways, which can utilize as photocatalytic H2 production to solve energy crisis. Spherical porous titanium dioxide materials, with nanostructures composition, were chemically synthesized, from titanate nanotubes via a simple hydrothermal technique, and added as a catalyst to accelerate the route of ammonium phosphate hydrolysis for hydrogen production process. The mechanism of sphere formation titanate nanotubes was elucidated in details through the current study. The prepared materials applied as a photocatalyst to ameliorate the separation, transfer of photo-induced electrons, and prevent the recombination of electron-hole pairs. Experimental results show that the obtained microspheres product possess significantly enhanced photocatalytic hydrogen (H2) production process performance. The photocatalytic hydrogen production amount of microspheres product is founded to be ⁓2.5 folds than that of titanate nanotube. Analytical techniques such as FESEM, HR-TEM, simulated visible solar light and XRD instruments were used for evaluation and characterization of the developed products as well as the detection of the route of hydrolysis for hydrogen production process.
