An efficient photocatalyst based on H₅PMo₁₀V₂O₄₀/UiO-66-NH₂ for direct hydroxylation of benzene to phenol by H₂O₂

Abstract

To realize the direct hydroxylation of benzene to phenol by hydrogen peroxide, an efficient photoactive catalyst system was prepared by the recombination of H5PMo10V2O40 and UiO-66-NH2.

An iron-containing POM-based hybrid compound as a heterogeneous catalyst for one-step hydroxylation of benzene to phenol

“…A comparison of the catalytic activity of Fe 2 -PMo 11 V 3 with several previously reported POM-based heterogeneous catalysts in the presence of H 2 O 2 is shown in Table 4. [55][56][57][58][59][60] The phenol yield of Fe 2 -PMo 11 V 3 (16.2%) was higher than those of most of the POM-based catalysts presented in Table 4.…”

Copper-containing POM-based hybrid P2Mo22V4Cu4 nanocluster as heterogeneous catalyst for the light-driven hydroxylation of benzene to phenol

“…[28][29][30][31] Due to their special structure, POMs have excellent photoactivity, strong acidity, and redox ability. [32][33][34][35] Unlike traditional Keggin-type polyacids H 3 PW 12 O 40 or H 3 PMo 12 O 40 , molybdenum vanadates (PMo 10 V 2 ) containing mixed metals and valence states can perform fast, reversible multi-electron transfer reactions, making them a good choice as photocatalysts. In recent years, POMs, as a hot spot, have attracted the attention of researchers.…”

Recent trends in phenol synthesis by photocatalytic oxidation of benzene

“…Photocatalytic processes have attracted attention as "green" alternatives because they can activate benzene molecules using light as an energy source and convert them to phenol under mild reaction conditions. [14][15][16] Several photocatalysts have been developed for benzene oxidation to phenol by oxidants, including H 2 O 2 and O 2 .…”
