Special Issue Information

Dear Colleagues,

To address the issues associated with climate change, raw materials, energy resources, and environmental pollution, transitioning from the utilization of fossil carbon resources to a renewable and decarbonized energy system is a potential route. The selective catalytic conversion of lignocellulose (a class of inedible and abundant renewable carbon feedstocks) and bio-derived compounds into value-added fuels and chemicals serves as a promising carbon-neutral strategy to drive this transition. However, the efficient fractionation of biomass and selective conversion of bio-derived platform chemicals essentially depend upon catalytic technologies, including catalyst development, catalytic systems, and reaction processes. Therefore,  catalysts based on, for example, zeolites, carbon materials, metal oxides, metal organic frameworks (MOFs), pincer complexes, Lewis acidic cations, metallic nanoparticles, and single-atom sites have attracted great attention.

This Special Issue aims to report the latest advancements in catalytic technologies for clean chemical synthesis and efficient biomass conversion and upgrading, including the design and optimization of heterogeneous as well as homogeneous catalysts for lignocellulose hemicellulose, cellulose, and bio-derived compound upgrading, as well as other clean chemical synthesis by selective hydrogenation, oxidation, and related topics in a batch or continuous model. Reviews, research articles, and communications related to the above-mentioned catalytic systems are welcomed.

As a type of sustainable and renewable natural source, biomass-derived 5-hydroxymethyl furfural (HMF) can be converted into high-value chemicals. This study investigated the interactions between silver (Ag) and oxide supports with varied reducibility and their contributions to tuning catalytic performance in the selective oxidation of HMF. Three representatives of manganese dioxide (MnO2), zirconium dioxide (ZrO2), and silicon dioxide (SiO2) were selected to support the Ag active sites. The catalysts were characterized by techniques such as STEM (TEM), Raman, XPS, H2-TPR, and FT-IR spectroscopy to explore the morphology, Ag dispersion, surface properties, and electronic states. The catalytic results demonstrated that MnO2 with the highest reducibility exhibited superior catalytic performance, achieving 75.4% of HMF conversion and 41.6% of selectivity for 2,5-furandicarboxylic acid (FDCA) at 120 °C. In contrast, ZrO2 and SiO2 exhibited limited oxidation capabilities, mainly producing intermediate products like FFCA and/or HMFCA. The oxidation ability of these catalysts was governed by support reducibility, because it determined the density of oxygen vacancies (Ov) and surface hydroxyl groups (OOH), and eventually influenced the catalytic activity, as demonstrated by the reaction rate: Ag/MnO2 (3214.5 molHMF·gAg−1·h−1), Ag/ZrO2 (2062.3 molHMF·gAg−1·h−1), and Ag/SiO2 (1394.4 molHMF·gAg−1·h−1). These findings provide valuable insights into the rational design of high-performance catalysts for biomass-derived chemical conversion. Full article
