The present paper reviews recent advances on the direct synthesis of 5-hydroxymethylfurfural (HMF) from different kinds of raw biomasses. In particular, in the paper HMF production from: (i) edible biomasses; (ii) non-edible lignocellulosic biomasses; (iii) food wastes (FW) have been reviewed. The different processes and catalytic systems have been reviewed and their merits, demerits and requirements for commercialisation outlined.

Five previously unreported 5-hydroxymethylfurfural (5-HMF) derivatives, including chinenfurfurals A () and B () as 5-HMF-citric acid hybrids and chinenfurfurals C-E (-) as 5-HMF oligomers, as well as four known analogues (-), were isolated from the fruits of a well-known Chinese herbal species . The structures of these furfural compounds were established by detailed analyses of spectroscopic data especially HRMS and NMR, and it is the first report of furfural type constituents from the title species. The anti-inflammatory property of them was further evaluated by testing their inhibition against the production of nitric oxide in lipopolysaccharide-activated murine RAW264.

Electrocatalytic biomass conversion offers a sustainable route for producing organic chemicals, with electrode design being critical to determining reaction rate and selectivity. Herein, a prediction-synthesis-validation approach is developed to obtain electrodes for precise biomass conversion, where the coexistence of multiple metal valence states leads to excellent electrocatalytic performance due to the activated redox cycle. This promising integrated foam electrode is developed via acid-induced surface reconstruction to in situ generate highly active metal (oxy)hydroxide or oxide (MOH or MO) species on inert foam electrodes, facilitating the electrooxidation of 5-hydroxymethylfurfural (5-HMF) to 2,5-furandicarboxylic acid (FDCA).

Electrocatalytic oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) is a promising alternative for oxygen evolution reactions. The search for efficient catalysts has been attracting increasing scientific attention. This work explores the performance of nitrogen-doped graphene-supported single-atom catalysts (M-NC SACs) for the reaction.

The electrocatalytic 5-hydroxymethylfurfural (HMF) oxidation reaction (HMFOR) toward 2,5-furandicarboxylic acid (FDCA) has been considered a promising approach for the substitution of the energy-consuming and hazardous oxygen evolution reaction and for the valorization of renewable biomass. However, it is limited by the susceptibility of HMF to the oxidative environment and requires efficient electrocatalysts. Herein, a NiMo complex (NiMo-N) is provided as the precatalyst for the HMFOR, exhibiting favorable performances with a current density of 450 mA·cm achieved at an anodic potential of 1.

The adulteration of honey is a globally growing issue due to its medicinal benefits and health-promoting properties. This problem primarily involves the addition of sugars and other substances. To address these concerns, a comparative study was conducted to investigate the dielectric and spectroscopic properties of pure, sugar solution added honey, and commercially available honey.
