Furthermore, the efficiency of LSPR hot electrons converted to chemical energy of reaction is very low due to the fast relaxation of carriers. It is extremely valuable to design Pd-based catalysts which have strong response to the visible light irradiation and high efficiency in photon to chemical energy. The Pd–CeO<sub>2</sub> catalyst was synthesized via the hexadecyl­trimethyl­ammonium bromide (CTAB) assisted liquid-phase reduction method to generate more active interfaces. The significant extinction of Pd–CeO<sub>2</sub> in the visible to near-infrared region indicates the strong electron interaction between Pd and CeO<sub>2</sub>. LSPR hot electrons, transferring from the Pd metal particles to the conduction band of ceria, promote the dissociation of adsorbed oxygen. Therefore, the reaction temperature of CO and toluene oxidation can be significantly lowered by visible light irradiation. The maximum light efficiencies of Pd–CeO<sub>2</sub> catalyst for toluene oxidation and CO oxidation are obtained as 0.42% and 1%, which benefit from the effective Pd–O–Ce interfaces. 2016-12-12 00:00:00 CTAB light irradiation LSPR Localized Surface Plasmon Resonance Assisted Photothermal Catalysis Pd metal particles liquid-phase reduction method toluene oxidation CO design Pd-based catalysts Visible Light Irradiation efficiency electron chemical energy
