TL;DR: In this article, N-interstitial Re-cluster catalysts supported on H-ZSM-5 were prepared by chemical vapor deposition (CVD) of methyltrioxorhenium, exhibiting high phenol selectivity for direct phenol synthesis from benzene and molecular oxygen.
Abstract: N-interstitial Re-cluster catalysts supported on H-ZSM-5 were prepared by chemical vapor deposition (CVD) of methyltrioxorhenium, exhibiting high phenol selectivity for direct phenol synthesis from benzene and molecular oxygen. The phenol selectivity was 88% in steady state and 94% for pulse reaction, where coexisting NH 3 was prerequisite to the phenol synthesis. We found the structure of active Re species in the presence of NH 3 as novel N-interstitial Re 10 clusters, which were characterized by XRD, XRF, XPS, solid-state NMR, TPD, XAFS, and DFT calculations.
