Optimized bifunctional CuNiMgAl catalysts for efficient synthesis of the renewable bioproduct glycerol carbonate

Biofuels, Bioproducts and Biorefining, Volume 19, Issue 5, Page 1271-1288, September/October 2025.
Abstract This paper presents a novel technology for converting glycerol, a byproduct of the biodiesel industry, into glycerol carbonate, a high‐value bioproduct. The effect of calcination temperature on the synthesis of quaternary Cu‐Ni‐Mg‐Al catalysts (MMO‐Cu15Ni15‐Tz) and their application in the transesterification reaction was investigated ...

Pd Nanoparticles Supported on Activated Carbon and Their Application in the Oxidative Condensation Reaction of Furfural: Effect of Base and Oxidizing Agent on Catalytic Behavior and Deactivation

ChemCatChem, Volume 17, Issue 17, September 5, 2025.
Catalysts with varying palladium (Pd) loading supported on activated carbon were assessed for their effectiveness in the oxidative condensation of furfural. Furan‐2‐acrolein was the primary product, depending on the palladium content. Reusability tests showed a decline in the yield of furan‐2‐acrolein.

Enhanced Oxygen Evolution Reaction Performance of Niobium–Cobalt Oxide Catalysts in Acidic and Alkaline Media

Advanced Sustainable Systems, Volume 9, Issue 8, August 2025.
The electronic modulation of Nb‐doped Co3O4 catalyst showcases enhanced activity and extended stability for OER in both alkaline (1M KOH) and acidic (0.5M H2SO4) electrolytes. The higher activity emanated from the synergistic effect between the Nb5+ dopant and Co3O4.
