Co decorated low Pt loading nanoparticles over TiO2 catalyst for selective hydrogenation of furfural

Regulation of Pt Loading on Co/Al2O3 Catalysts for Selective Hydrogenation and Hydrogenolysis of 5‐Hydroxymethylfurfural to 2,5‐Bis(hydroxymethyl)furan and 2,5‐Dimethylfuran

“…Many kinds of heterogenous catalysts have been designed and developed for the HMF hydro-conversion into BHMF and DMF products such as non-noble catalysts of Ni, Co, Cu, and Fe-based components and noble catalysts of Pt, Ru, Re, Ir, and Pd-based components in mono and bi-metallic forms. [12,[25][26][27][28][29][30][31][32][33][34] In applications of FAL, LA, and HMF hydrogenation, the combined nonnoble and noble catalysts such as NiÀ Re, [33] FeÀ Re, [35] CoÀ Pt, [36][37][38] NiÀ Pt, [39] and PtÀ CoÀ Ni [40] were stated to be a group of high activity and selectivity under low operating temperature. This was due to their outstanding in the geometrical and electronic modifications between two active constituents.…”

“…[38] The great affords regarding the development of CoÀ Pt catalysts were mostly associated with FAL hydrogenation. [36][37][38] The CoÀ Pt/TiO 2 catalysts were described to attain the high yield and selectivity of furfuryl alcohol (FOL) and tetrahydrofurfuryl alcohol (THFOL) from the FAL hydrogenation at the reaction temperature lower than 50 °C. [36,38] C. Liang et al elucidated the structure of CoÀ Pt catalyst and activity correlations that the oxophilic Co δ + species combined with nanosized Pt species were major reasons for a highly active and stabilized CoÀ Pt system based on the experimental and DFT investigations.…”

PHYSICO-CHEMICAL STUDIES OF Ru-CONTAINING CATALYSTS DURING SELECTIVE HYDROGENATION OF FURFURAL

“…Реакции гидрирования обычно проводят на катализаторах на основе металлов VIII группы (Ru, Rh, Pd, Os, Ir, Pt) из-за их способности восстанавливать карбонильную группу [7]. Однако активность и селективность этих катализаторов очень часто необходимо повышать 8 путем добавления соответствующего промотора.…”
