Honey-Derived Hydrochar Containing 2,2,6,6-tetramethylpiperidine-1-oxyl Free Radical for Degradation of Aqueous Organic Pollutants

Environmental Processes, Год журнала: 2024, Номер 11(4)

Опубликована: Ноя. 1, 2024

Abstract The increasing demand for greener technologies in environmental remediation makes carbon materials from biomass and its derivatives some of the most attractive resources a sustainable future. However, integrating these with stable free radicals remains challenging. This study presents straightforward one-pot hydrothermal route using raw honey as source 4-amino 2,2,6,6-tetramethylpiperidine-1-oxyl (4-amino-TEMPO) radical. addition TEMPO derivative initiates Maillard reactions between amino group carbonyl groups carbohydrates honey, resulting formation functionalized hydrochar spherical morphology (~ 8 μm). presence within carbonaceous matrix was confirmed by electron spin resonance spectroscopy, supported infrared elemental analysis, thermal scanning microscopy, X-ray photoelectron spectroscopy. radical content estimated at 0.4 mmol∙g -1 . material effectively removed methylene blue, fluorescein, doxorubicin water green oxidants like hydrogen peroxide sodium hypochlorite. After 24 h, removal efficiencies reached 92% doxorubicin, 73% 23% fluorescein. Moreover, demonstrated good regeneration capability, maintaining dye efficiency over several cycles.

Areca Catechu Biochar and Nano-Biochar as Adsorbents for Congo Red: Synthesis, Characterization, and Performance Evaluation

BULLETIN OF CHEMICAL REACTION ENGINEERING AND CATALYSIS, Год журнала: 2025, Номер 20(1), С. 112 - 128

Опубликована: Фев. 10, 2025

The presence of hazardous synthetic dyes such as Congo Red in industrial wastewater poses a significant environmental threat. This study explores the potential biochar (BC) and nano-biochar (nano-BC), derived from Areca catechu husk sustainable adsorbents for dye removal. Nano-BC was synthesised via hydrothermal carbonisation mechanical ball milling, leading to enhanced structural surface properties. X-ray Diffraction (XRD) revealed that Pinang is predominantly amorphous, while BC exhibits increased crystallinity with sharp peaks, nano-BC demonstrates highest nanostructural refinement. Fourier Transform Infra (FTIR) confirmed transformation aliphatic-rich raw biomass into aromatic-dominant structures nano-BC, showing more pronounced graphite-like features. Scanning Electron Microscope (SEM) illustrated morphological evolution, exhibiting refined, uniformly porous structures. BET analysis has significantly higher area 41.38 m²/g smaller pore size 8.4928 nm compared 22.38 15.39 nm, enhancing adsorption capacity. Furthermore, kinetics followed pseudo-second-order model, isothermal monolayer maximum capacity (Qmax = 154.526 mg/g). These findings highlight superior performance emphasising its environmentally friendly water treatment applications.
