Review of some transition metal-based mesoporous catalysts for the direct hydroxylation of benzene to phenol (DHBP)

Single-atom catalysts for catalytic benzene oxidation to phenol: recent progress and future perspectives

“…73,74 Furthermore, some porous supports will not only facilitate the mass transport, but also work as active sites for synergistically improving the catalytic performance. 75 Therefore, Pd SACs have been widely investigated and synthesized for facilitating benzene oxidation. For instance, Liu et al 76 synthesized a new type of supported bimetallic single-atom Pd and Co catalyst for catalytic benzene oxidation.…”

Recent trends in phenol synthesis by photocatalytic oxidation of benzene

“…14 Rahmani et al summarized developments in transition metal-based mesoporous catalysts for the hydroxylation of benzene to phenol. 13 Han et al reviewed heterogeneous photocatalytic hydroxylation of benzene to phenol since 2015. 23…”

Near-infrared photothermally enhanced catalysis for benzene hydroxylation

“…The high temperature and pressure, strong acid-base treatment, and low control of by-products are the main challenges in the past decades. 2 Thus, to overcome these limitations, the one-step hydroxylation of benzene becomes highly desirable, but the conversion and selectivity regarding green chemistry and economic efficiency are still far from satisfactory to date. Among the developed approaches, catalysts containing transition metals such as V, Fe, Co, Ni, and Cu have received much interest [3][4][5][6][7] because these transition metals provide both redox property and acidity for enhanced catalytic performance.…”
