[32] However, an interesting experimental phenomenon could be observed in Figure 1b. No obvious change in the concentration of lactic acid was detected in H 2 , even after 5 h, there only 1.1 % of lactic acid was decomposed, indicating that the formation of lactic anhydride existed in N 2 could be restrained in the presence of H 2 .…”

Catalytic conversion of glucose to lactic acid is a green promising strategy for the effective utilization of biomass‐derived carbohydrates to generate valuable chemicals. The generation of lactic acid would also be distinguishing in different reaction atmospheres. In this work, we firstly investigated the decomposition of lactic acid and glucose transformation to lactic acid in H2. No obvious decomposition of lactic acid was observed in H2. The activity testing results showed that glucose could be completely converted over the selected hydroxides, while the formation of lactic acid was closely related to the alkalinity of hydroxide. The yield of lactic acid was remarkably obtained to be 87 % over Ca(OH)2 at 220 °C for 3 h. Stronger alkalinity of the catalyst would facilitate glucose isomerization to fructose, and then easily be transformed into dihydroxyacetone or glyceraldehyde intermediates through reverse aldol condensation, which is beneficial to the generation of lactic acid.

“…Owing to its abundant and renewable character, as well as to its excellent inherent properties, cellulose is recently in the spotlight of scientific interest, , especially its nanoscale forms, cellulose nanofibers, nanocrystals, and bacterial nanocellulose. Low density, high surface area, high crystallinity, good thermomechanical properties, optical transparency, and biocompatibility are some of its most appealing features, rendering nanocellulose an excellent candidate for polymer reinforcement , with a wide range of applications such as packaging materials, adhesives, coatings, composite films, biomedical applications, printed electronics, and biosensors. ,− Alternatively, cellulose can be converted to glucose via downstream chemo/bio-catalytic hydrolysis, − which can be further upgraded to sugar alcohols, glycols, 5-hydroxymethylfurfural, and organic acids via catalytic hydrogenation/hydrogenolysis and oxidation. − …”

Sustainable production of bio-based materials and chemicals requires integrated approaches which utilize all fractions of lignocellulosic biomass. In this work, highly crystalline cellulose was isolated via combined pretreatment/fractionation and extraction processes from beechwood sawdust. The proposed approach was based on the selective recovery of hemicellulose components in the first step, followed by enhanced delignification in the second step, permitting the efficient recovery of the remaining cellulose via bleaching in the final step. Hydrothermal pretreatment under tailored conditions in neat water or dilute acid resulted in almost complete hemicellulose removal (80−96 wt %) in the liquid fraction. In the second step, the formed surface lignin was isolated via mild extraction while enhanced removal of both native/structural and surface lignin (71 wt %) was achieved by applying the organosolv treatment using dilute sulfuric acid as catalyst. Dilute sulfuric acid pretreatment followed by acid catalyzed organosolv pretreatment proved to be the most efficient combined approach, leading to 80 wt % hemicellulose removal as xylose monomer, and 71 wt % delignification. High crystallinity cellulose (<88%), with an overall cellulose recovery of 68−91 wt % based on native cellulose in parent biomass was isolated in the last step via bleaching of all pretreated biomass solids. The proposed integrated biorefinery procedures that aim to whole "waste" biomass valorization, replacing fossil resources, with the use of green solvents (water, ethanol) at relatively mild temperature/pressure conditions, are in line with the scope of several United Nations Sustainable Development Goals, such as UN SDG 8,11,12,and 13.

“…Moreover, transitioning to the production of chemicals and fuels from lignocellulosic biomass demonstrates a promising step towards achieving carbon neutrality. Previous works showed that various fuels and chemicals including alkanes [3], organic acids [4,5], furans [6,7], and ethanol [8] can be synthesized from lignocellulosic biomass as feedstocks. It is worth mentioning that glucose, a simple model compound of biomass, has been considered as a potential alternative to lignocellulose, which has a complex structure, in the investigation of photoreforming mechanisms [9].…”

The development of efficient and inexpensive photocatalysts for the production of high-value chemicals from the photoreforming of biomass is a highly attractive strategy to establish the production of chemicals from sustainable resources. In this work, Fe-loaded montmorillonite/TiO2 composite (Fe-Mt/TiO2), pure TiO2, Mt/TiO2 and Mt/Fe-TiO2 were fabricated and further utilized as photocatalysts for the production of formic acid from glucose under visible-light irradiation. Among the as-prepared composites, the Fe-Mt/TiO2 exhibited the highest glucose conversion (83%), formic acid production (44%) and formic acid selectivity (53%). The effective heterojunction between Fe-Mt and TiO2 is proposed to describe the superior photocatalytic activity of Fe-Mt/TiO2, which effectively suppressed the recombination of the photogenerated electrons and holes during the reaction. Mechanism investigations suggested that the selective photocatalytic oxidation of glucose into formic acid by Fe-Mt/TiO2 mainly occurred through an α-scission reaction pathway, driven by the main active species as •O2− and 1O2. The research findings in this work suggested that the Fe-Mt/TiO2 composite can be applied as a low-cost, easy-to-prepare, reusable and selective photocatalyst for sustainable synthesis of high-value chemicals from biomass-derived substrates.
