Applied Organometallic Chemistry, Год журнала: 2024, Номер 38(3)

Опубликована: Янв. 13, 2024

To boost the adsorption‐photocatalytic performances of biochar in wastewater treatment, was modified with ternary metal oxides ZnO, Sm 2 O 3 , and MgO (ZnSm/Mg‐biochar) via one‐step pyrolysis method. The optimal 2b‐ZnSm/Mg‐biochar a Zn/Sm molar ratio 1:1 exhibited better removal activity RhB comparison biochar, 2‐Mg/biochar, b‐ZnSm/biochar. efficiency adsorption capacity 99.46% 979.22 mg g −1 for solution 410 respectively. kinetics isotherms ZnSm/Mg‐biochar composites were as described by second‐order Langmuir models, abundant vacant sites at junction interface MgO, favorable photon capturing, achieving efficient photo‐conversion under stimulated solar‐light irradiation.

Impact of Milling Conditions on Hard and Soft Carbon Properties and Performance in Potassium-Ion Batteries

ACS Applied Energy Materials, Год журнала: 2024, Номер 7(8), С. 3378 - 3392

Hard carbon (HC) and soft (SC) are very attractive electrode materials for potassium-ion batteries (KIBs). However, specific attention must be devoted to preparation preserve their properties. This work reports the effects of milling conditions (ball hand grinding) used HC SC (or mixtures) on properties electrochemical performance. The were strongly affected by use ball instead grinding. Ball gave a homogeneous morphology with small particles but more disorganized structure containing inorganic impurities. A higher surface area, oxygen-containing groups, greater active area also generated. In addition, oxygen content (i.e., hard carbons) most influenced milling. These modified had negative impact contrast, grinding provided best initial Coulombic efficiency (ICE) capacity retention during cycling, i.e., 79% 91% after 50 cycles. Post-mortem XPS studies revealed nature solid electrolyte interphase (SEI) possible reasons low ICE. was tested in full cell vs C-coated KVPO4F0.5O0.5 delivered promising performance at high C-rates.

Engineered biochar derived from lemon peel waste for highly efficient removal of organic pollutants from water

Arabian Journal of Chemistry, Год журнала: 2023, Номер 16(10), С. 105158 - 105158

Опубликована: Июль 11, 2023

The urgent need for efficient decontamination of organic dyes from polluted waters necessitates the search a low-cost and suitable adsorbent. large amount lemon peel residue in actual production can be an ideal raw material preparation adsorbents. Herein, novel magnetic nanocomposite derived (Citrus limon L.) (Fe3O4/Lp-biochar) was successfully synthesized by one-step hydrothermal method used adsorptive capture methylene blue (MB) aqueous solution. prepared Fe3O4/Lp-biochar are spherical with particle size 8.3 nm have saturation magnetization intensity 52.9 emu/g specific surface area 64.30 m2/g. It found that maximum MB adsorption capacity 26.36 mg/g achieved when 0.10 mg/mL, system's pH value 10, reaction temperature 25 °C, time 60 min. Adsorption kinetics on followed pseudo-second-order kinetic model whilst Freundlich isotherm could well simulate behavior biochar. mechanism predominantly include electrostatic attraction mesoporous interaction. Furthermore, exhibited remarkable retention 94.7% initial efficiency even after 10th cycle repeated use. concluded peel-derived biochar promising alternative to conventional adsorbents wastewater treatment.
