Careful analytical determinations show that the gold‐catalysed aerobic oxidation of glucose occurs through a two‐electrons mechanism leading to gluconate and hydrogen peroxide. This latter decomposes before reaching the critical concentration for competing with O 2 in glucose oxidation. A mechanism of glucose oxidation on gold nanoparticles is presented.
