摘　　要： FeAPO-5 molecular sieves large single crystals 30 μm×100 μm along a and c directions were synthesized in fluoride system by using organic amine（Et3N） as the structure-directing agent. Its X-ray power diffraction pattern, thermal stability, scanning electron microscopy, etc. were studied. And its catalytic activity in hydroxylation of phenol with hydrogen peroxide as the oxidant was also investigated. The result shows that the phenol conversion is about 20.4% and the selectivities of catechol and hydroquinone are about 74.8% and 25.3%, respectively. It reveals that FeAPO-5 molecular sieve is a promising catalyst.
