CYCLOHEXANE OXIDATION OVER CuO THIN FILMS CHEMICALLY DEPOSITED ON FIBERGLASS
CuO thin films over fiberglass were prepared by chemical deposition and tested for cyclohexane oxidation. The catalytic fiber exhibited high activity for this process at low temperatures. The CuO/SiO 2 catalyst with the same CuO content was less active than the CuO/fiberglass system under the same conditions examined. However these catalysts gave a different product distribution at all temperatures. The effects of time-on-stream as well as reaction temperature upon the catalytic activity and selectivity of cyclohexane oxidation were investigated. Among the selected temperatures, the best one corresponds to 300°C. At this temperature, the steady-state catalytic performance of the CuO/fiberglass system was recorded with only a slightly deactivation after 4 h time-on stream in the present study.
