|摘要:||The purpose of this study was to prepare an activated carbon (AC)-supported copper catalyst by a simple method - the microwave polyol process - and to evaluate the effects of microwave power and protecting agent on the resulting catalyst activity. The catalysts were characterized by Brunauer-Emmett-Teller (BET) surface area. X-ray diffraction (XRD), and field-emission scanning electron microscopy (FESEM). Experimental results indicated that a microwave power of 700 W was highly effective, and that copper particles (60 (+/- 18) nm) dispersed well on the AC support, even in the absence of the protecting agent poly-vinyl pyrrolidone (PVP). The AC-supported Cu(0) catalyst generated high catalytic activity for CO oxidation (90% CO conversion at 175 C). (C) 2011 Elsevier B.V. All rights reserved.|
