Brief description not available

Inspired by biological systems, Prof. Jinyong Liu’s lab at UCR has developed a novel heterogeneous, bimetallic catalyst MoOx-Pd/C. The catalyst contains earth-abundant molybdenum (Mo) and the carbon support of Pd/C has a high capacity to accomodate MoOx species. The incorporation of a MoVI yields a highly active and robust catalyst. The porous carbon mimics the enzyme protein pocket (of microbes) to accommodate the oxygen atom transfer metal site. The representative figures shown below demonstrate the high activity and robustness of the catalyst for both chlorate and perchlorate reduction. The effect of concentrated salts on the reduction of 1 mM ClO3− by the MoOx-Pd/C catalyst at a loading of 0.2 g/L. The reactions were conducted at 25 oC and under 1 atm H2. Chlorine balance for ClO4- reduction Fig. 3 shows the profiles of the reduction of 0.18M ClO3− spikes in a multiple-spike reaction series. The decrease of activity was only caused by the gradual build-up of concentrated Cl− (see details in the publication).
