Book Description
The valorization of lignocellulosic biomass, in the form of forest and agricultural wastes, industrial processing side-streams, and dedicated energy crops, toward chemicals, fuels and added-value products has become a major research area with increasing exploitation potential. The efficient and tailored depolymerization of biomass or its primary structural components (hemicellulose, cellulose, and lignin) to platform chemicals, i.e., sugars, phenolics, furans, ketones, organic acids, etc. is highly dependent on the development of novel or modified chemo- and bio-catalytic processes that take into account the peculiarities and recalcitrance of biomass as feedstock, compared for example to petroleum fractions. The present Research Topic in Frontiers in Chemistry, Section of Green and Sustainable Chemistry, entitled “Nano-(bio)catalysis in lignocellulosic biomass valorization” aims to further contribute to the momentum of research and development in the (bio)catalytic conversion of biomass, by featuring original research papers as well as two review papers, authored and reviewed by experts in the field. The Research Topic addresses various representative reactions and processes in biomass valorization, highlighting the importance of developing novel, efficient and stable nano-(bio)catalysts with tailored properties according to the nature of the reactant/feedstock and the targeted products.

Book Description
Increasing energy requirements and environmental pollution, along with predicted shortages of fossil fuels in the near future, have accelerated the search for alternative renewable energy sources. Biomass is a promising renewable resource for the production of value-added fuels and chemicals. In this work, triglycerides, furfural and 5-hydroxymethylfurfural (HMF) are used as bio-derived feedstock chemicals for chemo- or electro-catalytic conversion to valuable chemicals that find applications in fuels, polymer, perfumery and pharmaceutical industries.Chemical interesterification of triglycerides was conducted with methyl acetate, as an alternative to transesterification, to co-produce biodiesel and a higher value-added compound, triacetin, instead of glycerol. Conversion of waste methyl acetate in terephthalic acid production industry using triglyceride into two valorized products biodiesel and triacetin is a novel idea. Biodiesel is a well-known renewable fuel and triacetin can be used as a fuel additive. Amongst various base catalysts screened, calcined Mg-Al hydrotalcite (Mg:Al mole ratio - 3:1) was found to have the best activity in terms triglyceride conversion and triacetin selectivity.We also studied the etherification of HMF with ethylene glycol to produce 5-(2- hydroxyethoxymethyl) furfural (HEMF), which finds application as a fuel additive. Metal substituted heteropoly acid catalysts were identified as a chemo-selective catalyst that favored etherification of HMF over acetalization reaction. Aluminum substituted dodecatungsto-phosphoric acid achieved the highest HMF conversion and HEMF selectivity, which was attributed to the combined role of the catalyst's Lewis and Bronsted acidity.Further, electrocatalytic hydrogenation (ECH) of furfural using zinc as a novel metal catalyst was studied to produce furfuryl alcohol and 2-methylfuran, which have applications in pharmaceutical, polymer and fuel industries. The effect of metal catalyst and electrolyte pH on the yield and Faradaic efficiency (FE) of the desired products was studied. Electrolysis at neutral pH (pH 6 to 8) exhibited increased yields and FE as compared to acidic and basic pH. FE for ECH of furfural with Zn was remarkably higher as compared to Cu and Ni.However, during ECH of furfural, the total yield of the desired products was low compared to the conversion of furfural which was due to electrodimerization reactions. Thus, zinc metal nanoparticles were synthesized by electrodeposition to achieve higher activity for furfural ECH as compared to bare zinc metal due to high surface area and roughness. Furfural electrolysis in 0.5 M bicarbonate electrolyte at -0.6 V/RHE yielded higher conversion, yield and FE as compared to bare zinc. Catalyst characterization revealed the presence of surface zinc oxide species post- electrolysis, which could have a role in reaction mechanism.Overall, this work contributes to the field of biomass valorization, by identifying new selective catalysts and processes to produce value-added chemicals using renewable bio-derived feedstocks. Catalyst synthesis, reaction engineering and process optimization studied for biomass conversion processes in this work will aid in future process intensification of such processes.
