【Abstract】 The catalytic activities of polyoxometalates for hydroxylation of phenol have been investigated. H 6P 2W 18 O 62 and K 5 PW 11 O 39 Mn(H 2O) are found to be superior catalysts for the reaction. The conversion of phenol reaches 31 0% and 28 4%, respectively, and the selectivity of hydroquinone reaches 77 4% and 90 5%, respectively.更多还原
