SUMMARY:Conférence du Professeur Aicheng Chen (Lakehead)
DESCRIPTION:Titre : Nanostructured Catalyst Design for Green Chemistry Appl
 ications.La conférence sera prononcée par le professeur Aicheng Chen d
 u Département de chimie de la Lakehead University. Elle sera donnée en a
 nglais. Résumé : Catalysis plays a key role in chemical production\, en
 ergy processing\, air purification\, water treatment\, food processing and
  life sciences. Nanostructured materials with high surface areas have rece
 ived widespread interest in electrocatalysis and photocatalysis due to the
 ir unique physical and chemical properties. In this talk\, I will present 
 the electrocatalytic activity of Pt and Pd based nanomaterials and the cat
 alysis of TiO2 based nanostructured photocatalysts. Pd possesses several e
 xceptional properties that enable promising applications in hydrogen purif
 ication\, storage and detection. The significant roles of Pd based nanomat
 erials in the development of a hydrogen economy will be highlighted. Plati
 num-based catalysts are vital to fuel cells\, sensors\, and the petroleum 
 and automotive industries\; the design of high-performance Pt based electr
 ocatalysts will be discussed. TiO2 is considered as one of the most promis
 ing photocatalysts due to its non-toxicity\, high stability and cost effec
 tiveness. The main drawback of TiO2 is the large band gap energy\; UV irra
 diation is required to initiate its photochemical process. The modificatio
 n of the TiO2 nanomaterials to achieve a visible light response will be pr
 esented. Potential electronic interactions and synergistic effects between
  the TiO2 nanotubes and the supported Pt nanoparticles will also be discus
 sed. Lien 1 : page web du Professeur ChenLien 2 : Chaire de recherche du
