Abstract:
The production of glucuronic acid (GA) directly from actual biomass via chemocatalysis is of great significance to the effective valorisation of biomass for a sustainable future. Herein, we have developed a one-step strategy for the conversion of cellulose in corncob residue into GA with the cooperation of Au/CeO2 and maleic acid, achieving a 60.3% yield. Experimental and density functional theory (DFT) results show that maleic acid is effective in the fractionation of cellulose from corncob residue and the depolymerisation of cellulose fragments to glucose, on account of the good capacity for

Abstract:
The use of renewable resources as feedstocks to ensure the production of goods and commodities for society has been explored in the last decades to switch off the overexploited and pollutant fossil-based economy. Today there is a strong movement to set bioeconomy as priority, but there are still challenges and technical limitations that must be overcome in the first place, particularly on biomass fractionation. For biomass to be an appellative raw material, an efficient and sustainable separation of its major components must be achieved. On the other hand, the technology development for biomas

This shows, for the first time, the conversion of 1,3-propanediol to C6 aldehydes in one pot via a catalytic hydrogen borrowing methodology.

In terms of tourism, about 10 per cent of the direct resources have already been valorised, while the remaining resources represent potential tourist attractions. The real tourist attractions are located in the lower valley, whereas the potential attractions are found in the middle and upper river valley. Access to potential attra

Abstract:
Biocatalytic cascades offer products of multistep synthesis without the use of protecting groups or isolation of intermediates. This strategy is particularly amenable to the synthesis of iminosugars, where traditional routes typically suffer from lengthy and inefficient steps. We have developed a one‐pot, three‐step biocatalytic cascade to synthesize trihydroxypiperidine and azepane iminosugars directly from monosaccharides, employing transaminase and galactose oxidase (GOase) enzymes.

AbstractHeterogeneous tin-based sulfonated graphite (Sn-GP) catalyst was prepared with graphite as carrier. The physicochemical properties of Sn-GP were captured by FT-IR, XRD, SEM and BET. Organic acids with different pKa values were used to assist Sn-GP for transforming corncob (CC), and a linear equation (Furfural yield = − 7.563 × pKa + 64.383) (R2 = 0.9348) was fitted in acidic condition. Using sugarcane bagasse, reed leaf, chestnut shell, sunflower stalk and CC as feedstocks, co-catalysis of CC (75.0 g/L) with maleic acid (pKa = 1.92) (0.5 wt%) and Sn-GP (3.6 wt%) yielded the highest fur

Abstract Purpose Algal research has been dominated by the use of marine biomass (mainly microalgae) as feedstock in the production of second-generation biofuels, albeit with limited economic success. A promising alternative strategy is the valorisation of seaweed (macroalgae), with the cascaded extraction of its high-value components, as well as lower-value components further downstream, under the ‘biorefinery concept’. The goal of this study was to assess the environmental performance of one such marine biorefinery situated in the UK. Methods Attributional life cycle assessment (LCA) was cond
