Abstract
Nanoparticles of Au(0) stabilized by Triton X-100 in water catalyze NADH oxidation. Oxygen and potassium ferricyanide can serve as electron acceptors from NADH. The NADH oxidase activity of Au(0) (normalized to gold concentration) is 0.08 turnover/min in air and 0.32 turnover/min in argon in the presence of K3FeCN6 (2 × 10−4 mol/l). The catalytic activity decreases with increasing gold concentration in the solution used for particle preparation and, accordingly, with increasing size of gold particles.
