Research Interests
Photocatlysts are chemicals or materials that can catalyze chemical reactions when activated by light. The photocatalysts that use water as a reaction media and/or as a reactant with visible light for activation are of great interest because such catalysts can lead to green chemistry for technology required for sustainable environment and energy, which are critical challenges that need our imminent action. Our research involves rational design, synthesis, and activity assessment of photocatalysts in application of degradation of organic pollutants or/and production of hydrogen gas as clean fuel by splitting water. The photocatalysts that we are currently studying are based on graphitic carbon nitride, which has exhibited photocatalytic activity under visible light. Graphitic carbon nitride that is considered as a structural analog of graphene can be made into materials with diverse morphology and desired properties.
In our research, g-C3N4 material-based catalysts have been designed and synthesized chemically in our laboratory; the structure, composition of the prepared catalysts are characterized and measured mostly by spectroscopic methods; photocatalytic activity will be assessed by monitoring the reaction under visible light using a UV-spectroscopic method. This research will yield the structure and composition-activity relationship of the photocatalysts and guide us to design more and more efficient ones; enrich our knowledge of photocatalysts; deepen our understanding of the photocatalytic mechanism, and ultimately provide catalysts for practical applications.
