Ag/GO/Fe3O4/γ-Fe2O3 Nanocomposite for Green-Light-Driven Photocatalytic Oxidation of 5-Hydroxymethylfurfural to 5-Hydroxymethyl-2-furancarboxylic Acid

“…In recent years, intermediate metal oxide nanomaterials, including zerovalent iron (Fe) nanoparticles, have become one of the promising candidates for environmental remediation due to their higher photocatalytic activity . In recent years, Fe 3 O 4 magnetic nanoparticles have attracted wide attention due to their wide application in magnetic resonance imaging clinical diagnosis, catalysts, environment, and wastewater treatment, such as chromium, nickel, and cadmium adsorption . Fe 3 O 4 is chemically stable, noncarcinogenic, and nontoxic, and has a high magnetic saturation value.…”

TiO2/g-C3N4/SO3H(IL): Unique Usage of Ionic Liquid-Based Sulfonic Acid as an Efficient Photocatalyst for Visible-Light-Driven Preparation of 5-HMF from Cellulose and Glucose

“…Lately, adherence to the green chemistry tenets has given rise to the emergence of a diverse range of chemical technologies, in large part due to the investment from government and nongovernment agencies. Photocatalytic processes offer one of the plausible solutions in conjunction with nanotechnology. − Consequently, the preparation and introduction of newer and sustainable photocatalysts are extremely important. The abundantly available titanium dioxide (TiO 2 ) is generally believed to be a prominent photocatalyst that performs under UV-light exposure − and stands out as one of the utmost examined semiconductors (n-type) because of its low cost, relative abundance, high photocatalytic efficiency, resistance to chemical and photocorrosion, eco-friendly nature, and relatively low toxicity .…”

Production of 5-Hydroxymethyl-2-furan Carboxylic Acid Using Biobased Silver Nanoparticles in Deep Eutectic Substrate Reaction Mixtures

“…Among the environmental problems identified in the past decade, environmental pollution, reduction of energy resources, and global warming are the most important. In this context, attention to the stability of chemical processes is necessary and researchers are currently focusing on this issue. − In particular, an effective strategy to cope with the reduction of fossil energy resources is the use of renewable raw materials such as biomass. − Indeed, the conversion of biomass into key building blocks or fine chemicals can allow for a partial replacement of fossil resources, and this field has become a major focus for both academia and industry. Among the platform molecules derived from lignocellulosic biomass, 5-hydroxymethylfurfural (5-HMF) is considered an important molecule with applications in biobased polymer chemistry. − Different chemical modifications of 5-HMF permit acquiring added-value chemicals: 2,5-bis­(hydroxymethylfuran) (BHMF) by reduction, 2,5-dimethylfuran (DMF) by hydrodehydroxylation, or 5-hydroxymethyl-2-furancarboxylic acid (HMFCA), 2,5-diformylfuran (DFF), 5-formyl-2-furancarboxylic acid (FFCA) by partially oxidation and 2,5-furandicarboxylic acid (FDCA) by per-oxidation (Scheme ).…”
