Me tetrahydrofuran-2-carboxylate (MeTHFC) and its derivatives are widely used as raw materials and intermediates in chem. industries. An efficient and clean method for the synthesis of MeTHFC was proposed, which included the oxidative esterification of biomass-based furfural into Me furoate and the selective hydrogenation of Me furoate into MeTHFC. The hydrogenation of biomass-derived Me furoate was investigated on Ni-SiO₂ catalysts with the different Ni contents prepared by a deposition-precipitation method. The Ni-SiO₂ catalyst with 50 wt% Ni loading displayed an excellent performance with a high conversion under mild reaction conditions. Moreover, this catalyst presented a slight decrease of conversion, probably due to the increasing Ni⁰ particle size and Ni leaching during 200 h time-onstream. Characterization results revealed that the formation of Ni phyllosilicates was responsible for high Ni dispersion and sp. surface area in the Ni-SiO₂ catalysts, which facilitate their hydrogenation performance.

Fan, Mengjiao;Li, Chao;Shao, Yuewen;Zhang, Shu;Gholizadeh, Mortaza;Hu, Xun research published 《 Pyrolysis of cellulose: Correlation of hydrophilicity with evolution of functionality of biochar》, the research content is summarized as follows. Biochar is a carbonaceous material from pyrolysis of biomass, the application of which is governed by its various properties such as the distribution of the functionalities and the associated hydrophilic/hydrophobic nature. This study particularly focused on the correlation of functionalities of biochar with its polarities by conducting the pyrolysis of cellulose from 200 to 700°C and the characterization of the biochar. The results demonstrated that -OH, instead of C=O or C-O-C, played decisive roles in formation of the biochar with hydrophilic surface. The results showed that the maximum of -OH abundance and the aliphatic C-H was reached at 440°C. The significant transition of oxygen-rich functionalities to carbon-rich functionalities occurred in the temperature from 460 to 700°C. The dominance of aromatization process above this temperature range resulted in the significant increase of hydrophobicity of the biochar. The hydrophilic surface was of importance for the use of biochar as support for promoting the dispersion of Cu in Cu/biochar by generating the bonding sites for chelating with Cu²⁺.

Developing the active and environmentally friendly non-noble nano-catalysts is highly desired to transform biomass-derived platform into value chems. Herein, we report a low-cost and sustainable cobalt/nitrogen-doped carbon catalyst containing both metallic Co and Co-N components exhibits satisfying activity for the oxidative esterification of 5-hydroxymethylfurfural and other investigated alcs. in methanol without the base additive under mild conditions. Exptl. results show that an appropriate ratio of Co to Co-N is responsible for the high activity of the Co/Co-N/CN catalysts towards oxidative esterification. Theor. computational results demonstrate that the Co/Co-N group synergistically promotes electron transfer from the Co adatom to the surface oxygen atoms, facilitates O₂ adsorption and activation on the Co sites, and further reduces the energy barrier for the oxidation of alcs. to aldehydes, all of which contribute to the overall activity of oxidative esterification of alcs. to the corresponding esters.
