Special Issue Information

Dear Colleagues,

To address climate and environmental issues related to the utilization of fossil carbon resources, a transition towards a renewable and decarbonized energy system is necessary. In this context, catalytic conversion of lignocellulose, a class of inedible and abundant renewable carbon feedstocks, into value-added fuels and chemicals has been intensively investigated as a promising carbon-neutral strategy to drive this energy transition. However, the efficient fractionation and conversion of lignocellulose is hindered by the complex compositions and diverse bonding motifs within lignocellulose and its derived platform chemicals. Of prime importance is the rational design of catalysts with tailored physicochemical properties capable of steering the reaction pathways towards the desired products. The last few years have witnessed the development of numerous heterogeneous and homogeneous catalyst systems based on zeolites, carbon materials, metal oxides, metal organic frameworks (MOFs), pincer complexes, Lewis acidic cations, metallic nanoparticles, single-atom sites, and so on. These catalysts systems have laid the foundation for the practical manufacture of chemicals and fuels from lignocellulose in a selective and efficient manner.      

This Special Issue aims to report the latest advancements in the design and optimization of heterogeneous as well as homogeneous catalysts for lignocellulose upgrading. Reviews and original papers or communications related to the development of all kinds of heterogeneous and homogeneous catalyst systems for the catalytic conversion of lignocellulose are welcome.

In organic synthesis, it is important to control the selectivity target product with high purity and reduce the cost of energy and equipment for separation. This study investigated supported gold catalysts on biochar-modified titanate-based nanofibers in order to regulate the catalytic performances by biochar content and surface properties. The catalysts were characterized by SEM, TEM, XRD, XPS, ICP-OES, UV-Vis to confirm their morphology, particle size distribution of Au NPs, crystal structures, oxidation state of Au and other key elements, real Au loading, and optical properties. In the test of selective oxidation of benzyl alcohol to benzaldehyde, the biochar modification could improve the selectivity toward benzaldehyde. Moreover, the influence of catalyst calcination conditions, reaction time, reaction atmospheres, reaction temperatures and solvent were systematically investigated. These results are useful for peer researchers in rational catalyst design. Full article

Noble metal-based catalysts are widely used to intensify the processes of reductive fractionation of lignocellulose biomass. In the present investigation, we proposed for the first time using the inexpensive NiCuMo/SiO2 catalyst to replace Ru-, Pt-, and Pd-containing catalysts in the process of reductive fractionation of abies wood into bioliquids and cellulose products. The optimal conditions of abies wood hydrogenation were selected to provide the effective depolymerization of wood lignin (250 °C, 3 h, initial H2 pressure 4 MPa). The composition and structure of the liquid and solid products of wood hydrogenation were established. The NiCuMo/SiO2 catalyst increases the yield of bioliquids (from 36 to 42 wt%) and the content of alkyl derivatives of methoxyphenols, predominantly 4-propylguaiacol and 4-propanolguaiacol. A decrease in the molecular mass and polydispersity (from 1870 and 3.01 to 1370 Da and 2.66, respectively) of the liquid products and a threefold increase (from 9.7 to 36.8 wt%) in the contents of monomer and dimer phenol compounds were observed in the presence of the catalyst. The solid product of catalytic hydrogenation of abies wood contains up to 73.2 wt% of cellulose. The composition and structure of the solid product were established using IRS, XRD, elemental and chemical analysis. The data obtained show that the catalyst NiCuMo/SiO2 can successfully replace noble metal catalysts in the process of abies wood reductive fractionation into bioliquids and cellulose. Full article
