<p>Formation of formic acid from renewable biomass resources is of great interest since formic acid is a widely used platform chemical and has recently been regarded as an important liquid hydrogen carrier. Herein, a novel approach is reported for the conversion of glucose, the constituent carbohydrate from cellulose fraction of biomass, to formic acid under mild hydrothermal conditions with simultaneous reduction of Ag<sub>2</sub>O to Ag. Results showed that glucose was selectively converted to formic acid with an optimum yield of 40.7% at a mild reaction temperature of 135 for 30 min. In addition, Ag<sub>2</sub>O was used as a solid oxidant for the glucose oxidation, which avoids the use of traditionally dangerous liquid oxidant H<sub>2</sub>O<sub>2</sub>. Furthermore, complete conversion of Ag<sub>2</sub>O to Ag can be achieved. This study not only developed a new method for value-added chemical production from renewable biomass but also explored an alternative low-carbon and energy-saving route for silver extraction and recovery.</p>

Simple Method

Biomass is an important renewable energy resource, which is used to replace the petroleum to produce chemicals. Glucose is a monomer of cellulose, which is the main component of biomass. In this work, conversions of glucose to value-added chemical by a simple method have been reported. TiO2 photocatalysts were fabricated by sol-microwave method. Value-added chemical production was successfully carried out via photocatalytic conversion of glucose with TiO2 photocatalysts. Arabinose, xylitol, gluconic acid, and formic acid were produced with photocatalytic reaction of TiO2 under UVA irradiation. The value-added products (gluconic acid, arabinose, and xylitol) can generally be further used as building blocks for biorefinery production, pharmaceutical production, and food industry. In the conventional sol-microwave method, the agglomeration of fabricated TiO2 particle was a limitation of photocatalytic activity. Therefore, the modification of TiO2 fabrication by use of zeolite as a TiO2 support was applied to increase efficiency of photocatalytic conversion of glucose and its selectivity. The effect of TiO2 dosage on zeolite (TiO2/zeolite) on photocatalytic activity and yield of products was monitored. The results from scanning electron microscopy (SEM) images indicated that zeolite supporter reduced agglomeration of spherical TiO2 particles. The well distribution of TiO2 particles on surface of zeolite particles could be observed in 15%TiO2/zeolite. It was found that the highest photocatalytic conversion of glucose (77.3%) was obtained from the use of 15%TiO2/zeolite as photocatalyst. The yields of gluconic acid, arabinose, xylitol, and formic acid were 8.6, 26.0, 3.7, and 33.89%, respectively.

Production of energy and chemicals from biomass resources has been regarded as one promising method to address the challenge of global warming. In this research, production of acrylic acid from fumaric acid, one of the biomass-derived building blocks, is proposed. CuO was employed as a solid oxidant, which showed excellent activity and selectivity for the production of acrylic acid, and water played an essential role in acting as not only a solvent but also a catalyst in this process. An optimum acrylic acid yield of 76.4% was successfully obtained after the reaction of fumaric acid with CuO at 300 °C for only 60 s.This research provides a green and highly efficient way to produce value-added chemicals from biomass-derived building blocks, and thus is promising for practical application.

Efficient conversion of renewable biomass into value-added chemicals and biofuels is regarded as an alternative route to reduce our high dependence on fossil resources and the associated environmental issues. In this context, biomass-based furfural and levulinic acid (LA) platform chemicals are frequently utilized to synthesize various valuable chemicals and biofuels. In this review, the reaction mechanism and catalytic system developed for the generation of furfural and levulinic acid are summarized and compared. Special efforts are focused on the different catalytic systems for the synthesis of furfural and levulinic acid. The corresponding challenges and outlooks are also observed.

Multiple Challenges

Lignocellulosic biomass feedstocks are promising alternatives to fossil fuels for meeting raw material needs of processing industries and helping transit from a linear to a circular economy and thereby meet the global sustainability criteria. The sugar platform route in the biochemical conversion process is one of the promising and extensively studied methods, which consists of four major conversion steps: pretreatment, hydrolysis, fermentation, and product purification. Each of these conversion steps has multiple challenges. Among them, the challenges associated with the pretreatment are the most significant for the overall process because this is the most expensive step in the sugar platform route and it significantly affects the efficiency of all subsequent steps on the sustainable valorization of each biomass component. However, the development of a universal pretreatment method to cater to all types of feedstock is nearly impossible due to the substantial variations in compositions and structures of biopolymers among these feedstocks. In this review, we have discussed some promising pretreatment methods, their processing and chemicals requirements, and the effect of biomass composition on deconstruction efficiencies. In addition, the global biomass resources availability and process intensification ideas for the lignocellulosic-based chemical industry have been discussed from a circularity and sustainability standpoint.
