Special Issue Information

Dear Colleagues,

The continuous growth of the population brings increasing pressure on energy and the environment. Using renewable biomass energy to produce high-value-added chemicals has become a key research field to reduce carbon dioxide emissions and achieve sustainable fuel and chemical production.

Due to the advantages of heterogeneous noble metal catalysts in selectivity and stability, it can achieve efficient REDOX conversion of organics under relatively mild conditions. With the support of the noble metal nanocluster synthesis technology, it is helpful to realize the specific exposure of the active sites on the heterogeneous noble metal catalysts and reduce the consumption of precious metals. It shows significant application advantages in the energy chemical industry and environmental protection.

Therefore, this Special Issue focuses on the biomass conversion of the heterogeneous noble metal catalysts. The biomass would cover sucrose, froctose, cellulose, 5-hydroxymethylfurfural, furfural, etc. The biomass conversion reaction may include hydrogenation, oxidation, oxidative esterification, etc., on the supported noble metal catalysts. We hope to educate researchers, allowing them to better understand the application of noble metal catalysts and the previously unknown mechanism of biomass conversion, thereby promoting biomass conversion as a viable alternative to coal and petroleum.

Abstract
One-step oxidative esterification of 2,5-furandiformaldehyde (DFF) derived from biomass to prepare Dimethyl Furan-2,5-dicarboxylate (FDMC) not only simplifies the catalytic process and increases the purity of the product, but also avoids the polymerization of 5-hydroxymethylfurfural (HMF) at high-temperature conditions. Gold supported on a series [...] Read more.
One-step oxidative esterification of 2,5-furandiformaldehyde (DFF) derived from biomass to prepare Dimethyl Furan-2,5-dicarboxylate (FDMC) not only simplifies the catalytic process and increases the purity of the product, but also avoids the polymerization of 5-hydroxymethylfurfural (HMF) at high-temperature conditions. Gold supported on a series of acidic oxide, alkaline oxide, and hydrotalcite was prepared using colloidal deposition to explore the effect of support on the catalytic activities. The Au/Mg3Al-HT exhibited the best catalytic activity, with 97.8% selectivity of FDMC at 99.9% conversion of DFF. This catalyst is also suitable for oxidative esterification of benzaldehyde and furfural. X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and CO2 temperature programmed desorption (CO2-TPD) were performed to characterize the catalysts. The results indicated that the medium and strong basic sites in the catalysts benefited for the absorption of intermediate agents and facilitated the oxidative esterification of aldehyde groups, while neutral or acidic supports tended to produce an acetal reaction. It is worth noting that basicity on the support surface reduced the electronic state of the Au nanoparticle (Auδ−) and, thus, enhanced the catalytic selectivity of oxidative esterification. This finding demonstrated that the support plays a crucial role in oxidative esterification. Full article
