摘要
Nanojewels as catalysts: Degradation of phenol with a small excess of H2O2 can be achieved by using gold nanoparticles supported on Fenton-treated diamond nanoparticles as a highly selective (at least 79 %) and efficient (turnover number: 321 000) catalyst for the Fenton reaction at room temperature. The proposed mechanism is shown schematically in the picture. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
