Efficient catalytic combustion of toluene at low temperature by tailoring surficial Pt(0) and interfacial Pt-Al(OH)(x) species

Exploring highly efficient and low-cost supported Pt catalysts is attractive for the application of volatile organic compounds (VOCs) combustion. Herein, efficient catalytic combustion of toluene at low temperature over Pt/γ-Al(2)O(3) catalysts has been demonstrated by tailoring active Pt species sp...

description Exploring highly efficient and low-cost supported Pt catalysts is attractive for the application of volatile organic compounds (VOCs) combustion. Herein, efficient catalytic combustion of toluene at low temperature over Pt/γ-Al(2)O(3) catalysts has been demonstrated by tailoring active Pt species spatially. Pt/γ-Al(2)O(3) catalyst with low Pt-content (0.26 wt%) containing both interfacial Pt-Al(OH)(x) and surficial metallic Pt (Pt(0)) species exhibited super activity and water-resistant stability for toluene oxidation. The strong metal-support interaction located at the Al-OH-Pt interfaces elongated the Pt-O bond and contributed to the oxidation of toluene. Meanwhile, the OH group at the Al-OH-Pt interfaces had the strongest adsorption and activation capability for toluene and the derived intermediate species were subsequently oxidized by oxygen species activated by surficial Pt(0) to yield carbon dioxide and water. This work initiated an inspiring sight to the design of active Pt species for the VOCs combustion.
