Tóm tắt

Abstract— Band gap illumination of TiO2 (anatase) dispersions in weakly alkaline solutions of nicotinamide‐adenine‐dinucleotide (NAD+) leads in the presence of rhodium trisbipyridyl complex [Rh(bipy)3+3], to continuous generation of biologically active cofactor NADH. Effects of pH, NAD+ and Rh(bipy)3+3 concentration on the efficiency of this photoconversion process are investigated. The reaction proceeds already in aqueous solution in the absence of external electron donors but it is enhanced significantly in the presence of 10% methanol.
