Cellulose-based Catalyst Design for Efficient Chlorate Reduction

Abstract

Abstract. The reduction of undesirable chlorate (ClO 3 ) is important from both an environmental and an industrial point of view. In our work, cellulose-based catalysts have been designed for chlorate reduction by using palladium, platinum, and iron oxide. The produced catalysts were characterized by SEM, TEM, XRD, FTIR, and ICP. Even though low precious metal content (<0.6 wt %) was used during the catalyst preparation, high catalytic activity was achieved, and the conversion was as high as 92.5%. Furthermore, a continuous chlorate hydrogenation and monitoring system has also been developed within which the reduction has been carried out successfully and after about 160 min the ClO 3 content has been reduced to zero.
