Aqueous-phase catalytic hydroxylation of phenol with H₂O₂ by using a copper incorporated apatite nanocatalyst

Abstract

/phenol ratio and catalyst mass have been investigated. Under the optimized conditions, the Cu-apatite catalyst gave a phenol conversion of 64% with 95% selectivity to dihydroxybenzenes. More importantly, the results of catalyst recycling indicated that the same catalytic performance has been obtained after four cycles with a slight loss of activity and selectivity.
