“…For example, the formation of byproduct of difructose anhydride ( F ) is promoted by strong acidic conditions. Consequently, the target product (5‐HMF) can further transform to polymers and humins or formic and levulinic acids via a rehydration reaction . Based on the above observations it is concluded that the best dehydration activity of PW 12 ‐ILs‐C4‐HNS catalyst can be attributed to its Brønsted acidity (Brønsted acid density of 1179 μeq g −1 and E i of 596.7 mV).…”

[54] Based on the above observations it is concluded that the best dehydration activity of PW 12 -ILs-C4-HNS catalyst can be attributed to its Brønsted acidity (Brønsted acid density of 1179 μeq g À 1 and E i of 596.7 mV). Finally, it is worth noting that the hydrophobic surface of as-prepared PW 12 -ILs-C4-HNS catalyst can promote the efficient removal of the water molecules produced from the catalyst's surface and accelerate the dehydration reaction.…”

As a biomass‐derived platform molecule, 5‐hydroxymethylfurfural (5‐HMF) is a highly desirable feedstock for manufacturing of high value‐added chemicals ranging from starting materials for polyesters to biofuels. In this work, we reported the fabrication of a series of multicomponent solid acid catalysts based on heteropolyacids immobilized ILs‐modified organosilica hollow nanospheres (denoted as PW12‐ILs‐Cn‐HNS), in which PW12 (PW12=H3PW12O40 ⋅ xH2O) provides Brønsted acid site, ILs show strong electrostatic interactions with PW12, Cn (Cn=alkyl chain) is attached for hydrophobicity and HNS represents organosilica hollow nanospheres. When applied for catalytic dehydration of fructose to 5‐HMF, the PW12‐ILs‐C4‐HNS catalyst with 15.2 % PW12 loading exhibited the best dehydration activity to 5‐HMF with 93.7 % yield in DMSO at 100 °C in 2 h. Compared with 2D hexagonal and 3D interconnected structures, the excellent porosity properties of hollow nanospherical structure can provide a high population of the PW12 sites and enough confined nanospace for the dehydration of fructose. Moreover, the PW12‐ILs‐Cn‐HNS catalyst showed excellent stability over six catalytic cycles without obvious loss of activity. Most importantly, careful identification of the observed intermediates revealed crucial information for the dehydration process of fructose to 5‐HMF. As such, the proposed heterogeneous catalysts show great potential in biomass conversion processes.

The rapid expansion of cities in sub-Saharan Africa generates increasing volumes of diversified organic wastes that require management and a high population need for local and fresh vegetables. Linking the different sources of organic materials generated in these cities with the needs of local food producers for fertilizers prepared from recycled organic materials is challenging. This requires that producers obtain the results they expect from the organic materials they recycle. Thus, recycling these organic materials in their raw form or after composting presents an opportunity for periurban agriculture, although the great variability in the quantity and quality of these materials raises questions about the consistency between their agronomic value and their economic value. In two large cities of Cameroon (Yaoundé and Bafoussam), different types of organic materials were sampled: unprocessed livestock waste and composts from manure or municipal solid waste. From an agronomic perspective, we calculated the fertilization value based on the nutrient (nitrogen, phosphorus, and potassium) content of the organic materials. From an economic perspective, we calculated the value based on the nutrient content of the organic materials and their substitution unit prices and recorded the current market price. This is the first time that this combined approach has been used in sub-Saharan Africa. Our results showed considerable variability and discrepancy in both the agronomic and the economic values. The market prices overvalued the urban composts by a factor of 6, while chicken feces were undervalued by a factor of 3. The unprocessed organic materials were the most interesting from an economic and agronomic perspective. Our findings suggest that (i) the composting process needs to be improved and (ii) the humus potential should be calculated to better assess the amendment value of organic materials and as a basis for adjusting their market price.

“…The diminishing of petroleum sources, the growth of energy demand combined with growing concerns about global warming and environmental pollution had made the efficient utilization of renewable lignocellulosic biomass to be hot and significant in both academic study and industrial application [1,2]. In the utilization of lignocellulosic biomass, the conversion of glucose, which is the most abundant component in lignocellulosic biomass and the most available and low-cost six carbon monosaccharide [3], into value-added chemicals is significantly important [4,5]. Among the various value-added chemicals, HMF is considered as one of the "top 10" platform chemicals, which can be used as a raw materials to synthesize ocean of fine chemicals and other materials to replace or at least minimize the utilization of fossil-based products, such as 2,5-diformylfuran and 2,5-furandicarboxylic acid, 2,5-dimethyl-furan [6][7][8].…”

A simple solid acid catalyst γ-AlOOH was employed to synthesize 5-hydroxymethylfurfural (HMF) from glucose in the dimethyl sulfoxide. Various reaction parameters, such as catalyst loading, temperature, reaction duration and solvent, were investigated. A high HMF yield of 61.24 % was obtained at the mild reaction condition of 130 °C for 3 h. More importantly, the catalyst γ-AlOOH could be reused for several times without the loss of its significant catalytic activities. After five reaction runs, a HMF yield about 57.23 % was obtained. In addition, the results demonstrated that the γ-AlOOH also had high catalytic activities on the degradation of other polysaccharides, like Maltose, Sucrose and Cellulose, into HMF using ionic liquid 1-butyl-3-methylimidazolium chloride, DMSO and a small amount of water as the reaction solvents. For instance, a high HMF yield of 50.26 % was obtained at 170 °C for 2.5 h on the decomposition of Cellulose.
