Selective hydroxylation of benzene is a felicitous strategy for the production of phenol that is deemed to be an alternative to conventional processes. Thus, the development of a durable and highly efficient catalyst for the selective hydroxylation of benzene should be a key topic. In this work, FeOCl was prepared by a chemical vapor transition method and characterized using various techniques including XRD, TEM, Raman spectroscopy, N2 adsorption–desorption, DLS, and TGA. The prepared FeOCl was applied as a heterogeneous catalyst in benzene hydroxylation, and the reaction conditions were optimized. The acquired data manifested that FeOCl has shown superiority over the other reported catalysts utilized in benzene hydroxylation. The superiority of FeOCl is attributed to the facile self-redox potential of FeOCl and its remarkable ability for the production of an overwhelming amount of hydroxyl radicals in a short period of time. The catalyst recovery and reuse test showed that FeOCl is able to endure the harsh conditions of benzene hydroxylation for four runs. The mechanism of benzene hydroxylation using FeOCl as a catalyst in the presence of hydrogen peroxide as an oxidant was also illustrated.

氯氧化铁作为苯选择性羟基化为苯酚的有效催化剂
苯的选择性羟基化是生产苯酚的有利策略，被认为是常规方法的替代方法。因此，开发用于苯的选择性羟基化的耐用且高效的催化剂应该是关键主题。在这项工作中，FeOCl是通过化学气相转移方法制备的，并使用多种技术进行了表征，包括XRD，TEM，拉曼光谱，N 2吸附-解吸，DLS和TGA。制备的FeOCl作为多相催化剂用于苯羟基化反应，并优化了反应条件。所获得的数据表明，FeOCl已显示出优于苯羟基化中使用的其他报道的催化剂的优越性。FeOCl的优越性归因于FeOCl的容易的自氧化还原电势及其在短时间内产生大量的羟基自由基的显着能力。催化剂的回收和再利用测试表明，FeOCl能够在四次运行中经受苯羟基化的苛刻条件。还说明了在过氧化氢作为氧化剂存在下，使用FeOCl作为催化剂进行苯羟基化的机理。
