One of the main challenges in environmental remediation is creation stable and effective photocatalysts to eliminate organic contaminants when exposed visible light. For degradation N-chloropiperidine, a persistent pollutant with multiple dangerous issues, we provide synthesis, characterization, photocatalytic evaluation Ni/NiO-incorporating carbon nitride (Ni/NiO-C3N4) composite this work. The Ni/NiO-C3N4 photocatalyst was created by single step thermally polymerizing nickel nitrate melamine. Four samples are ranged Ni concentration from 0% 10%. coexistence NiO phases confirmed structural morphological analyses using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM), Fourier-transform infrared spectroscopy (FTIR). UV−Vis diffuse reflectance (DRS) also demonstrated an enhanced capacity absorb A study performance under light illumination showed that degraded N-chloropiperidine at much faster rate than either pure (0.0231 min−1), first-order constant 0.0456 min−1. reaction nearly quadrupled 10% added C3N4 matrix. Furthermore, composite’s activity performed better its counterparts Ni-C3N4 (0.0315 min−1) NiO-C3N4 (0.0386 min−1). synergistic interaction between NiO, which promotes charge separation lowers electron–hole recombination, responsible for higher Ni/NiO-C3N4, increasing production reactive oxygen species. reusability experiments conducted over four successive cycles slight decrease activity, indicating prepared reusable.

Geo-Spatial Insights into Heavy Metal Contamination and Ecological Implications in River Sediments: Identifying Agrochemical Impacts Through Pollution Indices in Morocco’s Sidi Allal Tazi Region, Sebou Basin

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: April 18, 2025

Sediments in agricultural ecosystems serve as critical indicators of environmental pollution, particularly regions subjected to intensive practices. This research evaluates the hazards and implications heavy metal (HM) contamination river sediments from Sidi Allal Tazi area within Morocco’s Sebou basin. Twenty sediment samples were extracted strategically designated locations, levels analyzed using a multi-index integration approach, multi-statistical analyses (MSA), Geographic Information Systems (GIS). The results revealed considerable spatial variability HM concentrations, with Cd As displaying highest levels. Statistical analysis, incorporating Principal Component Analysis (PCA), identified anthropogenic activities primary contributors contamination. Hierarchical Cluster (HCA) categorized metals based on common pollution pathways, while GIS mapping distribution across vulnerable areas. Pollution like Geo-accumulation Index (I_geo) well Load (PLI). that 75% sites under “very high pollution”, emphasizing severity Contamination Factor (CF) classified 90% 100% contamination”. Risk indices indicated significant ecological threats, contributing an RI exceeding 600 many areas, signifying risk”. These findings highlight urgent need for targeted mitigation strategies sustainable methodologies provides comprehensive framework assessing managing contamination, offering insights policymakers managers.

Chemical Physics Impact, Journal Year: 2024, Volume and Issue: 8, P. 100510 - 100510

Published: Feb. 5, 2024

The intrinsic structural characteristics of covalent organic frameworks (COFs) significantly influence their adsorption capabilities, particularly in the context glyphosate. In this study, diverse COFs, incorporating distinctive functional groups (-COOH, -NH2, -NO2, and -CF3), were strategically designed to showcase effectiveness functionalized COFs adsorbing glyphosate utilizing density theory (DFT) at M06-2X/Gen/6-311G(d)/LanL2DZ method. non-covalent nature interactions seen systems was through a visual such as QTAIM NCI analyses. phenomena results chemisorption, with GCS@COF-NH2 (CN1) complex possessing highest negative energy -1.313 eV. Also, relatively higher values observed GCS@COF-CF3 (CC1) (-1.305 eV), GCS@COF-COOH (CC2) (-1.239 GCS@COF-NO2 (CN2) (-1.147 eV) complexes. surfaces are stabilized due increment Eg upon adsorption, CN2 CN1 complexes least gap values, indicating lower stability electrical conductivity, electron distribution, sensitivity.
