Abstract:
Catalysts based on Rh(III) complexes with amine polymers PEI and AN-221 are shown to be active and stable catalysts for dihydrogen evolution from water by such strong one-electron reductants as V2+(aq) and Cr2+(aq). For granular Rh—AN-221 at high ( > 5 × 10−3 M) V2+concentration, the rate of hydrogen evolution was found to be determined by diffusion of the reaction products, i.e. V3+ cations and/or hydrogen molecules, inside the polymeric granules. The highest specific catalytic activity registered for the polymeric catalysts equals 640 mol H2 (g-atom Rh)−1 h−1 for Rh—AN-221. The active component of the rhodium-polymeric catalysts was proved by a number of physical methods to be highly dispersed metallic rhodium particles chemically bound to the polymer. The electronic properties of rhodium differ somewhat from those of bulk metal due to a strong interaction between the rhodium particles and the polymeric support.
