Abstract The preparation of biochar (BC) as a useful substance generated from biomass valorization via pyrolysis has attracted much attention in recent years. Moreover, widespread worries about water pollution and the issues brought on by producing releasing massive volumes industrial effluents have sparked research initiatives to examine practical affordable solutions these problems. Dyes, heavy metals, pharmaceutical compounds are main hazardous pollutants wastewater. As result, (BC)/biochar (BC)-based nanocomposites been presented potential alternative handle wastewater with both adsorption photocatalytic degradation processes. Such nanocomposite materials benefit synergistic effect photocatalysis attain improved removal Therefore, this review aims describe different methods for biochar-based nanocomposites. Furthermore, differences between processes discussed. BC-based emerged promising adsorbents photocatalysts treatment applications. To maximize efficiency processes, an overview parameters affecting is reviewed, where dose, initial pollutant concentration, pH, temperature, time, presence anions, recycling discovered significant impact their performance. Finally, future recommendations directions provided help shape applications This offers comprehensive evaluation use new environmental material capable removing Graphical

Green Organo-Photooxidative Method for the Degradation of Methylene Blue Dye

ACS Omega, Год журнала: 2024, Номер 9(10), С. 12069 - 12083

Опубликована: Фев. 28, 2024

This study used an organophoto-oxidative material to degrade the toxic azo dye, methylene blue (MB), due its hazardous effects on aquatic life and humans. MB is traditionally degraded using metal-based catalysts, resulting in high costs. Several organic acids were screened for organo-photooxidative applications against various dyes, ascorbic acid (AA), also known as vitamin C, was found be best degradation photooxidative activity. It eco-friendly, edible, efficient material. A photocatalytic box has been developed of that when AA added, efficiency increased from 42 95% within 240 min. Different characterization techniques, such HPLC GC-MS, after structural elucidation products. DFT done investigation mechanistic behind process. statistical tool, RSM, optimization parameters (concentration catalyst, time). develops sustainable effective solutions wastewater treatment.

Biomass photorefinery over a sustainable biochar (BC)-based heterojunction provides promising approach to alleviate the worsening environment and energy crisis via hydrogen (H2) valuable chemicals production. Moreover, no related results have been reported. Here, novel BC-supported CdS/TiO2 photocatalyst (CdS/TiO2/BC) was rationally fabricated by simple hydrothermal calcination methods for glucose photoreforming. The selectivity of value-added modulated alteration base type. BC, with large specific surface area outstanding electrical conductivity, employed as carrier heterojunction, which further facilitated light absorption charge separation. as-synthesized CdS/TiO2/BC exhibited excellent acetic acid (63.94%) together improved H2 generation (∼12.77 mmol g–1 h–1) in 25 mM NaOH solution, while efficient formic (60.29%) (∼10.29 were observed 3 Na2CO3 solution. Trapping tests indicated that ·O2– ·OH promoted production acid. This study initiates insight into design environmentally friendly photocatalysts fuel from biomass photorefinery.
