Effects of plasmon excitation on photocatalytic activity of Ag/TiO2 and Au/TiO2 nanocomposites

Effective Electron Transfer Pathway of the Ternary TiO2/RGO/Ag Nanocomposite with Enhanced Photocatalytic Activity under Visible Light

“…Combining TiO 2 with graphene could enhance the photocatalytic capacity, which facilitates the charge separation and transportation and suppresses the recombination of photogenerated electrons and holes [19][20][21]. Besides graphene, the decoration of noble metal Ag could enhance the photocatalytic activity of TiO 2 photocatalysts, due to the local surface plasmon resonance (LSPR) effect for optimizing the use of solar energy and improving the transfer efficiency of photogenerated carriers [13,[22][23][24][25][26].…”

Synthesis of hierarchically porous metal oxides and Au/TiO2 nanohybrids for photodegradation of organic dye and catalytic reduction of 4-nitrophenol

“…Of the many catalysts that have been proposed, those involving metal oxide supports (such as TiO 2 , Fe 2 O 3 , ZnO, and CeO 2 ) and noble metal nanoparticles are the most attractive, as such a combination could give rise to improved catalytic performance through synergistic interactions between metal oxides and noble metal nanoparticles [15][16][17]. In particular, gold nanoparticles on metal oxide supports have been found to be very active as heterogeneous catalysts for a variety of chemical reactions [18][19][20].…”

Gold-nanoparticle-modified TiO2 nanowires for plasmon-enhanced photocatalytic CO2 reduction with H2 under visible light irradiation

“…The Au-NPs/TiO 2 NWs exhibited higher photoactivity for CO 2 reduction, and yield of CH 3 OH increased gradually by increasing the contents of Au-NPs, suggesting Au-NPs have great effect on the performance of TiO 2 NWs. Conceivably by contacting Au-NPs with TiO 2 , the plasmon-excited electron can be injected into TiO 2 and being trapped by Au-metal resulting in prolonged recombination time [17]. The energy of the trapped electrons is enhanced via SPR effect of Au-NPs.…”
