Abstract Here, porous carbon (PC) and ZnO nanorods@PC (ZnO-NR@PC) composite derived from orange peel (OP) have been synthesized via a simple carbonization process. The prepared materials characterized by XRD, FT-IR, TEM, BET analysis. adsorptive properties of the PC ZnO-NR@PC investigated toward methylene blue (MB) crystal violet (CV) cationic dyes their aqueous solutions. adsorption studies concluded that maximum efficiency was achieved after 90 min in basic conditions (pH = 10). Langmuir, Freundlich, Dubinin–Radushkevich (D-R), Temkin non-linear isotherm models were applied to fit experimental data. MB CV OP is fitted with Freundlich model, both Langmuir model. estimated capacity 74.45 74.89 mg/g, respectively. calculated free energy D-R indicates MB, dye molecules OP, PC, may be physical. kinetic revealed onto pseudo-second-order On otherhand, thermodynamic confirmed an endothermic spontaneous Furthermore, displayed high stability overall removal about 90% five cycles. mechanism proposed controlled electrostatic bonding, π-π interactions, ion exchange. results indicated potential ability OP-derived carbons as adsorbents for media.

Abstract Valorization of biomass wastes into carbon‐based catalysts for water treatment is a clear paradigm sustainability.Herein, we investigate an unprecedented transformation pine needle waste activated biochars (PNCs) as ozonation aqueous oxalic acid degradation. The physico‐chemical and textural properties PNCs are tailored by combining pyrolysis temperatures up to 1200 °C the use or not KOH K 2 CO 3 activating agents. structural these carbocatalysts correlated with their catalytic activities. PNC catalyst pyrolized at 4 h using (PNC1200‐4K ) provides complete pollutant degradation after 150 min, while without activation requires 300 min. PNC1200‐4K performance compares favorably previous reports. superior activity this reusable attributed its highest population π‐extended aromatic domains active sites together high porosity. formation 1 O , HO . HOO radicals supported electron paramagnetic resonance measurements selective quenching experiments. Unlike most analogous reports, herein, demonstrate that in presence can degrade even common radical scavengers.
