“…However, in a heterogeneous catalytic system, highly dispersed metal NPs always possess more accessible catalytically active sites. It is well‐documented that hydrogen donors can be chemisorbed dissociatively over metal particles to generate active hydrogen atoms, and hydrogen is further transferred to reactant molecules . However, compared with other catalysts, Co‐Ru/C with a lower dispersion and reduction degree of Ru species possesses a smaller amount of accessible active Ru 0 , which is disadvantageous for the dehydrogenation of benzyl alcohol and thus the hydrogen transfer for the hydrogenation of carbonyl group in FA.…”

The synthesis of highly efficient supported metal catalysts is of vital importance for the modern development of the production of chemicals. In this regard, biomass‐based chemical transformation holds potential promise through many heterogeneous catalytic processes. Herein, we report surface defect engineering on a carbon‐supported, Ru‐based catalyst by a two‐step hybridization–self‐reduction route, which involves the assembly of a hybrid composite of ternary Co‐Al‐Ru layered double hydroxide (CoAlRu‐LDH) and amorphous carbon through the carbonization of glucose and a subsequent in situ self‐reduction process. The results revealed that Ru3+ species in the resulting CoAlRu‐LDH‐C composite could be reduced in situ to Ru0 species by the carbon component in the hybrid composite, and Co‐containing spinels with a large quantity of surface oxygen vacancies could be formed simultaneously on the surface. The as‐fabricated Ru‐based catalyst showed a superior catalytic performance in the liquid‐phase transfer hydrogenation of furfural to furfuryl alcohol using benzyl alcohol as hydrogen donator to other Ru‐based catalysts derived from LDH‐C composite precursors. It was proven that surface defects (i.e., oxygen vacancies, Co2+ species) could enable the chemisorption of furfural spatially and ensure the activation of its carbonyl groups, which promoted the transfer hydrogenation greatly.

Catalytic Transfer Hydrogenation of Furfural to Furfuryl Alcohol over Nitrogen‐Doped Carbon‐Supported Iron Catalysts

Iron-based heterogeneous catalysts, which were generally prepared by pyrolysis of iron complexes on supports at elevated temperature, were found to be capable of catalyzing the transfer hydrogenation of furfural (FF) to furfuryl alcohol (FFA). The effects of metal precursor, nitrogen precursor, pyrolysis temperature, and support on catalytic performance were examined thoroughly, and a comprehensive study of the reaction parameters was also performed. The highest selectivity of FFA reached 83.0 % with a FF conversion of 91.6 % under the optimal reaction condition. Catalyst characterization suggested that iron cations coordinated by pyridinic nitrogen functionalities were responsible for the enhanced catalytic activity. The iron catalyst could be recycled without significant loss of catalytic activity for five runs, and the destruction of the nitrogen-iron species, the presence of crystallized Fe2 O3 phase, and the pore structure change were the main reasons for catalyst deactivation.
