Recent developments in electrode materials for the selective upgrade of biomass-derived platform molecules into high-value-added chemicals and fuels

Abstract

As the “fourth-largest energy source” and “only renewable organic carbon source”, biomass and its derived platform molecules (BDPMs) are widely used to be selectively upgraded into high-value-added chemicals and fuels,...

Recent progress of Cu-based electrocatalysts for upgrading biomass-derived furanic compounds

“…, wind and solar power), electrocatalytic conversion provides a more promising alternative at ambient temperature and pressure. 13,14 By replacing the traditional additives with clean electrons as oxidizing/reducing agents, it enables selective, environmentally friendly, and energy-benign transformation towards the target products by accurately controlling the external currents or potentials (Fig. 2).…”

“…With high surface activity, multiple oxidation states (Cu 0 , Cu I , and Cu II ) and rich earth-abundance, Cu has attracted considerable interest as a non-precious electrocatalyst for various electrocatalytic applications. 22–25 Recently, Cu has been applied in the ECH and ECO of furans, 14 accomplishing witnessed progress in an electrochemical refinery. Based on the Sabatier principle, the binding energies (BEs) of substrates and *H or *OH can be employed as fundamental descriptors to define the ECH or ECO rate and activity of electrocatalysts.…”

Highly selective photocatalytic oxidation of 5-hydroxymethylfurfural by interfacial Pt–O bonding Pt–Ov–BiOBr

“…One of these, 5-hydroxymethylfurfural (HMF), was listed as one of the twelve biomass platform chemicals by the American Academy of Sciences and has been extensively studied for the synthesis of a number of high value-added downstream products. 2 For example, 2,5-furandicarboxaldehyde (DFF), which has two aldehyde groups and a furan ring, can be produced through polymerization, hydrogenation, hydrolysis, oxidation, and other processes. 3 Currently, one of the most significant directions in biomass oxidation is the oxidation of HMF to DFF.…”

New multicomponent reactions in water: a facile synthesis of 1,3-dioxo-2-indanilidene-heterocyclic scaffolds and indenoquinoxalines through reaction of ninhydrin-malononitrile adduct with diverse N-binucleophiles

“…8,9 This “green” approach includes the identification of alternative chemical reactions to achieve environmental and economic advantages. 10,11 Therefore the synthetic value of MCRs will definitely increase when they are carried out in an aqueous medium.…”
