Effect of hydrothermal and deep eutectic solvent solvothermal pretreatments on the structural evolution of corncob-derived activated carbons for enhanced hydrogen storage and CO2 capture.
Agricultural residues are promising precursors for sustainable porous carbons, but their activation efficiency strongly depends on precursor chemistry. Here, corncob-derived activated carbons were prepared through three routes: direct KOH activation, hydrothermal carbonization followed by KOH activation, and acidic dee...
