摘要
A series of superconductor-type cuprates synthesized by citric acid complex method exhibited high catalytic activity in direct hydroxylation of phenol to diphenols. The relationship between catalytic activity and structure of catalysts was. investigated by means of chemical analysis and O-2-TPD. It was found that the average valence of copper and the contents of nonstoichiometric oxygen could be the key factors to control the hydroxylation activity of phenol and the decomposition activity of H2O2. The mechanism involving the role of electron transfer of quinones was also proposed.
