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.展开更多
