Preparation of Electroless Copper Plated Activated Carbon Fiber Catalyst and Reactive Evaluation of NO Removal

摘要

Pitch based activated carbon fiber(ACF) was prepared from reformed naphtha cracking bottom oil(NCB oil) by melt spinning. Hie fibers obtained were stabilized, carbonized, and then steam activated The ACF was sensi-tized with Pd-Sn catalytic nuclei via a single-step activation approach. This sensitized ACF was used as precursors for obtammg copper plated ACFs via electroless plating. ACFs uniformly decorated with metal particles were obtained with reduced copper plating in the reaction solution. Effects of the amount of copper on characteristics of ACF/Cu catalysits were investigated through BET surface area, X-ray diffraction, scanning emission microscopy and ICP. The amount of copper increased with plating time, but the surface area as well as the pore volume decreased. NO conversion increased with reaction temperature. NO conversion decreased with increasing the amount of copper, which is seemed to be due to the reduction of surface area as well as the dispersion of copper.
