Trace Al/Rb regulation stabilizes Cu-Fe5C2 active sites for ambient-pressure photothermal CO2 hydrogenation to C2-C4 olefin

Photothermal hydrogenation of CO2 offers a solar-driven route to multicarbon hydrocarbons, but controlling carbide formation and maintaining reconstructed active sites remain challenging for iron-based catalysts. Here, we develop a trace Al/Rb co-promoted CuFe2O4 catalyst that en...

Steam-activated/H 3 PO 4 functionalized biochars from grape wastes for drug adsorption

Grape waste was used to produce steam-activated biochars functionalized with H3PO4 (BAP-CWR) for drug uptake from aqueous media. The BAP-CWR exhibited favorable adsorption properties, enabling distinct interactions with diclofenac potassium (DCF) and ivermectin (IVM). The experim...
