“…However, homogeneous catalysts are difficult to recycle, which may hinder their practical application. Heterogeneous catalysts, such as mesoporous silica loaded with transition metals, have been investigated for direct catalysis of the hydroxylation of naphthalene, but the final yields are low [12,13].…”

“…However, the occurrence of excessive oxidation for gas‐phase oxidation resulting that carbon dioxide was the main product, which would cause both resource waste and greenhouse effect . Silicon‐based materials such as Fe‐SBA‐15, V–MCM‐41, Fe‐SiO 2 , Mn(TF5PP)‐MCM‐41 and V‐ZSM‐22 have been developed as catalysts for the liquid‐phase oxidation of naphthalene to prepare fine chemicals. But the catalysts preparation process was complicated and the reaction conditions were rigorous.…”

The characterization of XRD, N2 sorption, Raman, Py‐IR, O2‐TPD, NH3‐TPD, SEM‐EDX and TEM were utilized to investigate the influence of titanium species on the ordered mesoporous structure of V‐doped titanium and zirconium composite metal oxides (VTZ) catalysts prepared by EISA method. The characterization results showed that the introduction of titanium species would increase the catalyst crystallization temperature resulting in pure t‐ZrO2 phase formation with uniform distribution for all elements and more oxygen vacancies owing to the inhibition of its crystal transformation, which would be beneficial to the promotion of specific surface area and stronger Brønsted acidity. The catalytic performance in the liquid‐phase oxidation of naphthalene with hydrogen peroxide was also studied. The 12V15TZ‐550 catalyst with the molar ratio of vanadium and titanium species to the total titanium and zirconium species of 12 and 15%, respectively, calcined at 550 °C showed higher catalytic performance than other catalysts, where the naphthalene conversion of 17.3% and the 1,4‐naphthoquinone selectivity of 71.0% can be obtained. The catalytic stability would be kept well after repeated use for 5 times.

“…10 Liquid-phase oxidation of naphthalene for the preparation of fine chemicals has been exploited over mesoporous silica-based materials, such as Fe-SBA-15, V-MCM-41, Fe-SiO 2 , and Mn(TF 5 PP)-MCM-41. [11][12][13][14] But their catalytic activities were low and time-consuming catalyst preparation procedure was required. Compared to the mesoporous silica-based materials, the non-siliceous mesoporous materials such as mesoporous metal oxides and heteroatom zeolites have recently been proposed as potential catalysts in many catalytic industries.…”

The ordered mesoporous V-m-Al 2 O 3 catalysts were successfully synthesized via a facile one-pot evaporation-induced self-assembly (EISA) strategy and applied in the liquid-phase oxidation of naphthalene with hydrogen peroxide in the presence of ascorbic acid as a reductant. The physicochemical properties of the catalysts were investigated using various techniques, like XRD, N 2 sorption, UV-Vis spectra, Raman spectroscopy, XPS, XRF and TEM. Small-angle XRD, N 2 sorption and TEM results show that mesoporous V-m-Al 2 O 3 catalysts possess a highly ordered mesostructure with large surface areas and narrow pore-size distributions. Highangle XRD, UV-Vis spectra and Raman spectroscopy results indicate that VOx species were homogeneously incorporated in the matrix of mesoporous Al 2 O 3 .The catalytic performance in the liquid oxidation of naphthalene with H 2 O 2 over 8V-m-Al 2 O 3 catalyst (naphthalene conversion 45.4% and phthalic anhydride selectivity 61.0%) was higher than other catalysts. The vanadium species incorporated in the 8V-m-Al 2 O 3 sample were stable, and its catalytic stability was kept well even after repeated use for 5 times, which indicates a green and economical pathway for naphthalene degradation.
