▎ 摘 要
In this work, we report the synthesis of reduced graphene oxide (rGO) modified platinum (Pt) catalysts for decreasing the temperature of the complete conversion of benzene. The X-ray photoelectron spectroscopy (XPS) analysis reveals the presence of electron transfer between rGO and Pt, which has a significant effect on the catalytic activity. The electron transfer is also proved by Raman spectra in term of the shifting of G-band belonging to the rGO. H-2-temperature programmed reduction (H-2-TPR) results indicate that the rGO facilitates the reduction of surface oxygen over the catalyst. Moreover, increasing the concentration of rGO within a certain range has a positive influence on the catalytic activity. (C) 2015 Elsevier B.V. All rights reserved.
