Description
Summary:Over the years, several forms of energy resources have been used for a variety of purposes; however, the over use of energy supplies has resulted in a variety of problems. Renewable energy sources are an excellent approach for addressing these challenges. In recent years, it has become possible to modify photoelectrochemical cells with titanium dioxide, cadmium sulfide, and graphitic nitride to create clean hydrogen. It has been discovered that the doping method enhances the photocatalytic activity of the catalyst. Metal-oxide nanoparticles are common dopants; one example of this is iron-doped TiO 2 , which exhibits remarkable quantum efficiency due to the presence of iron. Nanomaterials with excellent crystallinity, three-dimensional structure, and tiny size are needed for obtaining high photocatalytic efficiency. The focus of the current research is on clean fuel production (hydrogen synthesis) using a doped titanium dioxide photocatalyst. In addition to clean fuel generation, attention is being paid to the development of titanium dioxide doping technologies and the doping of titanium dioxide. Experimental manufacturing approaches have been investigated to achieve this goal. Both theoretical (computational) and experimental methodologies have been discussed that aid in reducing band gap of pure Anatase TiO 2 and may help in achieving better photocatalytic water splitting (PWS) for hydrogen production.
