“…Due to the ever-increasing environmental concerns caused by our continuous consumption of fossil fuels, significant attention has been given to renewable resources like biomass [1][2][3][4][5]. Furfural (FF), bearing a natural furan ring and an active aldehyde group, has been recognized as a promising platform molecule derived from renewable biomass [6,7], which plays a crucial role in the production of pharmaceuticals, paints, plastics, pesticides, and various other industries [8,9]. Recently, intensive investigations have focused on the FF conversion due to its potential to undergo diverse transformations into furan derivatives under certain reaction conditions, including hydrogenation, oxidative esterification, oxidation condensation, ammonification, and so on [10][11][12][13][14][15].…”

The use of gold nanoparticles (Au NPs) as catalysts has gained widespread attention in various reactions due to their high activity and selectivity under mild reaction conditions. However, one major challenge in utilizing these catalysts is their tendency to aggregate, leading to catalyst deactivation and hindering their amplification and industrial application. To overcome this issue, herein, we used a method by coating the surface of Au NPs with a thin layer of SiO2, which resulted in the formation of a superior catalyst denoted as Au@SiO2/ZA. Characterization studies revealed that the SiO2 layer is coated on the surface of Au NPs and effectively prevents the aggregation and growth of the gold particles during the reaction process, which makes the catalyst display excellent stability in furfural (FF) oxidative esterification to methyl furoate (MF). Moreover, the stabilization strategy is not limited to SiO2 alone. It can also be extended to other oxides such as ZrO2, CeO2, and TiO2. We believe this work will provide a good reference for the design and development of an efficient and stable gold catalyst for the oxidative esterification reaction.

“…Electrocatalytic oxidation technology is an attractive option for effectively and e ciently converting FF under ambient conditions without the need for additional oxygen or oxidants [7][8]. The e cient conversion of FF to FA generally requires an alkaline environment and noble metal-based electrocatalysts (such as Ru [9] and Ir [10]).…”

The use of electrocatalytic technology to replace traditional harsh thermocatalysis in the process of biomass utilization has undoubtedly been an effective means to achieve green and sustainable development. The use of the environmentally friendly method of synthesizing furoic acid (FA) from the biomass platform compound furfural (FF) by electrooxidation was investigated. The surface of the Ni-Co oxide electrode with a Ni content of 0.48 (Ni 0.48 Co 0.36 O 0.16 ) obtained by a simple electrodeposition method was covered by a layer of ower-like porous structure, while NiO and Co 3 O 4 coexisted. Moreover, the Ni 0.48 Co 0.36 O 0.16 electrode exhibited 95.4% FA faraday e ciency and 99.6% selectivity with a substrate concentration of 20 mM at 1.0 V vs. Hg/HgO and 50°C. In addition, a mechanism for electrooxidation of FF into FA over a Ni-Co oxide electrode was proposed.

The use of electrocatalytic technology to replace traditional harsh thermocatalysis in the process of biomass utilization has undoubtedly been an effective means to achieve green and sustainable development. The environmentally friendly way of furoic acid (FA) synthesis from biomass platform compound furfural (FF) by electrooxidation was investigated. The surface of Ni–Co oxide electrode with the Ni content 0.48 (Ni0.48Co0.36O0.16) obtained by a simple electrodeposition method was covered by a layer of flower-like porous structure, while NiO and Co3O4 were coexist. Moreover, Ni0.48Co0.36O0.16 electrode exhibited 95.4% FA faraday efficiency and 99.6% selectivity with substrate concentration of 20 mM at 1.0 V vs. Hg/HgO and 50oC. In addition, the mechanism for electrooxidation of FF into FA over Ni-Co oxide electrode was proposed.
