The Pt/(Fe, Mn/Co)-BTC catalysts were fabricated by a facile ultrasonic impregnation assisted hydrothermal polyol reduction method using first MIL-100(Fe, Mn/Co) MOFs as supports and tested for selective hydrogenation of furfural (FAL) to furfuryl alcohol (FOL). Various characterizations including XRD, TG, FT-IR, N2 physical adsorption, ICP-OES, SEM, TEM and XPS were applied for exploring structure changes and surface properties of the catalysts. Over 98% conversion of FAL and 99% selectivity to FOL were achieved over Pt/(Fe, Mn)-BTC and Pt/(Fe, Co)-BTC, moreover, Pt/(Fe, Co)-BTC showed higher turnover frequency (TOF) of 1,044 h−1 and better cycle stability, which are better than other catalysts prepared by using H2, NaBH4, and formaldehyde as reductants. Overall, the formation of highly dispersed small-sized Pt NPs (about 1.7 nm) with much higher content of surface Pt0 on the catalysts is the key of excellent hydrogenation activity due to the strong interaction between Pt NPs and the bimetallic supports.

Pt–Co alloy supported on SBA-15 catalysts (Pt–Co/SBA-15) were prepared by impregnation and NaBH4 reduction method. Their catalytic performances were investigated for selective hydrogenation of cinnamaldehyde. It was found that the formation of Pt–Co markedly enhanced the conversion to cinnamaldehyde and selectivity to cinnamyl alcohol compared with Pt/SBA-15. Meanwhile, the Pt–Co/SBA-15-0.6 catalyst performed the best catalytic activity that 71 % CAL conversion and 91 % selectivity to COL were attained. Moreover, no obvious deactivation was observed after using 4 times for Pt–Co/SBA-15-0.6. This improvement was contributed to the formation of Pt–Co alloy, which increased the amount of the Pt0 species on the catalysts. Pt–Co alloy supported on SBA-15 catalyst shows excellent catalytic selective hydrogenation of cinnamaldehyde to cinnamyl alcohol

Cu-SBA-16 has been prepared by one-pot synthesis method, and Characterized by XRD, TEM, and N2 adsorption measurements. An extended study about the nature of copper species in the Cu-SBA-16 has been performed by FT-IR, UV-DRS, H2-TPR and XPS. The copper species is mainly present on the mesoporous SBA-16 in the form of isolated mononuclear Cu2+ ions and highly dispersive CuO nanoclusters. The excellent catalytic activity has been obtained for phenol hydroxylation due to the presence of high amount of highly dispersive Cu species. The conversion to phenol and selectivity to diphenol are 29.4 and 91.5%, respectively. A simple EISA strategy for direct synthesis of mesoporous Cu-SBA-16 containing isolated mononuclear Cu2+ ions and highly dispersive CuO clusters which shows an excellent catalytic performance for phenol hydroxylation.

La-Mn-O perovskite catalyst was successfully prepared by microwave irradiation processing using only several minutes for heat treatment, and characterized by XRD, SEM, XPS, H2-TPR and O2-TPD. The catalyst by microwave irradiation processing with 6 min, mainly non-stoichiometric excess oxygen LaMnO3.15 phase, shows excellent catalytic performance. Compared with the sample prepared by conventional method, it possesses relative higher surface area, the increase in Mn4+ and oxygen vacancy content and the enhancement in the mobility of lattice oxygen which play an important part in the methane combustion.
