Abstract:		"Solar energy conversion is a promising strategy to enhance the elimination of volatile organic compounds (VOCs) and minimize power consumption. Herein, non-noble metal WC@WO(3) as cocatalyst was composited with CeO(2) to optimize photochemical and photothermal conversion for the catalytic ozonation of toluene and acetone. The photothermal conversion efficiencies of visible and infrared lights on 20%WC@WO(3)-CeO(2) were 2.2 and 10.4 times higher than those on CeO(2), respectively, which indicates that the equilibrium temperature of the catalyst remarkably increased under full-spectrum light irradiation. Moreover, WC@WO(3) transferred electrons to CeO(2) in 20%WC@WO(3)-CeO(2) and thus remarkably improved the activity of catalytic sites. The synergy factor of light and O(3) on 20%WC@WO(3)-CeO(2) was 5.8, and the reaction rate of toluene and acetone reached 9274.5 and 35779.0 mg/(m(3)?O+min), respectively. This work provides a low-cost and high-efficient catalyst for the utilization of solar energy for VOC control"
