Site isolated Ru clusters and sulfoacids in a yolk-shell nanoreactor towards cellulose valorization to 1,2-propylene glycol

Spatial compartmentalisation effects for multifunctionality catalysis: From dual sites to cascade reactions

“…To this end, Yang et al [7] developed a highly selective metal-acid catalyst (Ru/NC@void@MC-SO3H) that isolates metal-acid sites by layer-by-layer assembly prior to chemical transformation. For the difficulties of hydrolysis and hydrogenolysis, sulfonic acid functionalized mesoporous carbon shells based on resorcinol-formaldehyde resin were designed for the hydrolysis of cellulose, while Ru clusters (1.4 nm) were constructed on N-doped carbon cores derived from Ru-containing ZIF-8 for the anti-hydroxyl aldol condensation with the promotion of basic N dopants (Figure 1a).…”

“…Reaction conditions: cellulose 0.20 g, catalyst 0.06 g, H2O 20 mL, H2 6 MPa, 230°C and 5 h. c) Possible reaction pathways for cellulose hydrogenolysis to 1,2-PG on Ru/NC@void@MC-SO3H. d) Comparison of the productivity of 1,2-PG over different Ru-containing acidic catalysts [7].…”

Ag-doped Pd nano-dendritic for promoting the electrocatalytic oxidation of ethylene to ethylene glycol

“…6,7 The BtEG method is to convert biomass to sugar alcohol or syngas and then form EG. [8][9][10] Compared with the CtEG pathway, the BtEG method has low environmental costs but high direct production costs. 11 Therefore, there is an urgent demand to develop environment-friendly, low-cost, and simple processes to implement the efficient synthesis of EG.…”

Degradation of phenolic compounds in wastewater using a conical-shaped packed-bed microbial fuel cell in continuous flow with recycling

“…This organic compound is a common precursor for synthesizing various chemicals, including adhesives, laminates, resins, detergents, cosmetic antifreeze, pharmaceutics, and paints. 14 However, the overuse of 1-2-PD has been recognized to cause severe diseases, categorized in bio-magnification, such as depression, bradycardia, arrhythmia, and dermatitis. 15,16 First, the development and operation of the SCMFC, including the synthesis of anode beads and the air-cathode disc, are described.…”
