My research objective focus on the synthesis and characterisation of various semiconductor metal oxide nanomaterials and their energy and environmental applications. The synthesis of metal oxides nanomaterials such as TiO 2 , ZnO, CeO 2 , SiO 2 , Al 2 O 3 and their mixed oxides is carried out through aqueous as well as hybrid processes. This type of semiconductor metal oxide nanomaterial have found promising applications such as water purification, self-cleaning and anti-fogging coatings on various substrates such as glass, metal, plastics and ceramics (tiles and sanitary wares) and Electrode material for super capacitor and Dye sensitised solar cells.
Contributions to Teaching:
My teaching interests are Environmental Chemistry, Environmental Pollution, Environmental Law and Management. I will try to make subject as simple, interesting subject to learn by using a variety of methods to engage students as actively as possible. I will make it possible by means of class room lectures, independent projects, small group of problem solving and questions throughout a lecture. As a teacher I am responsible to assess student’s needs and adjust teaching methods accordingly. I believe communication in the classroom must be bidirectional to be truly effective. This requires that students realize they are part of the learning process and I will make them comfortable enough to express both intellectual leaps and lack of understanding. It requires that they are part of classroom community whose common goal is for everyone to learn as much as possible.
