Best director: The direct synthesis of phenol from benzene and O2 was performed with 78–94 % selectivity on Pt/β and Pt‐Re/ZSM‐5 catalysts, regulated by NH3 (see figure, (1)). An alternating process (see figure, (2)‐1 and (2)‐2) afforded the selective synthesis of phenol with 83–99.8 % selectivity, whilst minimizing the consumption of NH3.
New and selective IrO2 cluster/β and NiO cluster/β catalysts have been synthesized for the direct synthesis of phenol from benzene with O2 in gas‐phase single‐path flow reactions. Phenol is generated by switchover of the reaction pathway from complete oxidation of benzene to selective hydroxylation of benzene by NH3. The active oxide‐cluster structures in the β pores have been characterized by XAFS, XPS, STEM‐EDS, XRD, and DFT calculations. The reaction profile and the role of NH3 in the synthesis of phenol on the proposed Ni4O4 cluster have also been simulated by DFT calculations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
