Improved catalytic activity of SiC supported Ni catalysts for CO2 reforming of methane via surface functionalizations

摘要

The effect of surface functionalizations on structural and catalytic properties of SiC supported Ni catalysts for CO2 reforming of methane has been investigated. Commercial SiC was surface functionalized to form a carbon composite (C-SiC) and an N-doped carbon composite (N-C-SiC) at the interface of SiC. Micro- and meso-pores were generated after surface functionalizations. The reforming activity followed the sequence of Ni/N-C-SiC>Ni/C-SiC-Ni/SiC, which can be rationalized by the enhanced Ni dispersion and enriched basic sites on the functionalized catalysts. The present work demonstrates surface functionalization as a simple method to improve the catalytic activity of SiC supported catalysts. (C) 2016 Elsevier B.V. All rights reserved.
