Title
Study of the activity and backscattered electron image of Pt/CNTs prepared by the polyol process for flue gas purification
Abstract

Pt catalyst is supported on the carbon nanotubes (CNTs) by the polyol process. To evaluate the activity of Pt/CNTs, we performed catalytic redox reactions with various reaction constituents, such as CO, toluene, CO and NO, and toluene and NO in the presence of 6% O2. These investigations indicated that the efficient removal of pollutants is attributed to the high dispersion of 2–3 nm Pt particles on the CNTs. Based on the backscattered electron image, platinum dispersion on carbon supports can be observed clearly. In the presence of toluene and NO, the Pt/CNTs catalyst shows a good redox reaction for NO removal, and toluene is a better reductant than CO.

Graphical abstractThis study investigated the employment of the CNTs as catalyst supports, where the catalyst is prepared by the polyol process. Based on the backscattered electron image, platinum (2–3 nm) dispersion on carbon supports can be observed clearly.Figure optionsDownload full-size imageDownload as PowerPoint slide
