Core–Shell Composites Based on Multiwalled Carbon Nanotubes and Cesium Tungsten Bronze to Realize Charge Transport Balance for Photocatalytic Water Oxidation

摘要: Core–shell composite photocatalysts based on multiwalled carbon nanotubes (MWCNTs) and Cs2W3O10 are first synthesized by an ion-directing method. Cs+ is preadsorbed the surface of MWCNTs electrostatic forces directs crystallization to form a uniform layer MWCNTs. This core–shell arrangement MWCNT@Cs2W3O10 photocatalyst with 15 nm thick allows charge transport balance be achieved in photocatalytic water oxidation process confers high photoactivity. Other reference that deviate from this result deteriorated The established synthetic method provides new for design synthesis photocatalysts, realization helpful understand nature enhancement photoactivity processes.
