Emission of greenhouse gases and infectious diseases caused by improper agro-waste disposal has gained significant attention in recent years. To overcome these hurdles, can be valorized into valuable bioactive compounds that act as reducing or stabilizing agents the synthesis nanomaterials. Herein, we report a simple circular approach using Citrus reticulata Blanco (C. reticulata) waste (peel powder/aqueous extract) green capping/stabilizing Zn nitrate/acetate precursors to synthesize ZnO nanoparticles (NPs) with efficient antimicrobial photocatalytic activities. The obtained NPs crystallized hexagonal wurtzite structure differed clearly their morphology. UV–vis analysis showed characteristic broad absorption band between 330 414 nm belonging NPs. Fourier transform infrared (FTIR) spectroscopy exhibited Zn–O close 450 cm–1. gap values were range 2.84–3.14 eV depending on precursor agent used. crystallite size from size–strain plots measured XRD patterns was 7 26 nm, strain 16 4%. highly crystalline nature confirmed clear ring diffraction d-spacing observed lattice fringes.

Photocatalytic activity of the biogenic mediated green synthesized CuO nanoparticles confined into MgAl LDH matrix

Scientific Reports, Год журнала: 2024, Номер 14(1)

Abstract The global concern over water pollution caused by organic pollutants such as methylene blue (MB) and other dyes has reached a critical level. Herein, the Allium cepa L. peel extract was utilized to fabricate copper oxide (CuO) nanoparticles. CuO combined with MgAl-layered double hydroxides (MgAl-LDHs) via co-precipitation method varying weight ratios of CuO/LDHs. composite catalysts were characterized tested for degradation MB dye. CuO/MgAl-LDH (1:2) showed highest photocatalytic performance achieved 99.20% degradation. However, only 90.03, 85.30, 71.87, 35.53% dye degraded CuO/MgAl-LDHs (1:1), (2:1), CuO, MgAl-LDHs catalysts, respectively. Furthermore, pseudo-first-order rate constant 0.03141 min −1 while constants 0.0156 0.0052 , results demonstrated that exhibited an improved catalytic than pristine MgAl-LDHs. higher performances may be due uniform distribution nanoparticles into LDH matrix, surface area, lower electron hole recombination rates. Therefore, catalyst can one candidates used in environmental remediation.

Cellulose‐Supported SnW(S,O)₄ Bimetal Sulfo‐Oxide Catalysts for the Catalytic Reduction of Pollutants in the Dark

Опубликована: Янв. 1, 2025

Abstract In this paper, cellulose‐supported SnW(S,O) 4 bimetal sulfo‐oxide catalysts (labeled as SnWSO‐C or SW@C) with exceptional catalytic performance in the reduction of MB, RhB, and Cr(VI) presence NaBH under dark conditions were synthesized via an in‐situ hydrolysis method. The catalyst system diverse tree species Pinus massoniana (Pm), Populus tomentosa Carrière (Ptc), Rice hull (Rh), Phyllostachys edulis (Pe) was investigated. 100 mL solutions MB (20 ppm), RhB (50 ppm) completely reduced by SW@Cotton, SW@Pe, SW@Rh, SW@Ptc, SW@Pm within 10, 7, 13, 4, min for MB; 8, RhB; 5, 8 Cr(VI), respectively. Among them, SW@Pe exhibits highest efficiency excellent stability, maintaining a removal rate 96% after six cycles. superior attributed unique properties cellulose, characterized low crystallinity (53.25%), minimal ash content (0.15%), lowest degree polymerization (1267). These features facilitated improved dispersion SnWSO sulfo‐oxide, leading to smaller crystal size, lower electrochemical impedance (2.24 Ω), larger electrochemically active surface area (21.86 mF/cm 2 ). This study demonstrates potential wastewater treatment, which is significant advancing future research on environmental pollution management using biomass‐based materials.
