Abstract: Catalysis plays a key role in chemical production, energy processing, air purification, water treatment, food processing and the life sciences. Nanostructured materials with high surface areas have received widespread interest in electrocatalysis and photocatalysis. Recently, my research team has designed and studied a variety of novel functional nanomaterials. In this talk, I will report briefly on the electrocatalytic activity of Pt and Pd based nanomaterials and the catalysis of TiO2 based nanostructured photocatalysts. Pd possesses several exceptional properties which may enable promising applications in hydrogen purification, storage and detection. The significant role of Pd based nanomaterials in facilitating the growth of a hydrogen economy will be addressed. Platinum-based catalysts are vital to the development of fuel cells and sensors; the design of high-performance Pt based electrocatalysts will also be discussed. TiO2 is considered to be one of the most promising photocatalysts due to its non-toxicity, high stability and cost effectiveness. The modification of TiO2 nanomaterials in the achievement of visible light response will be presented. In addition, the application of functional nanomaterials in electrochemical biosensing will be highlighted.
