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.

The utilization of solar energy as a pivotal and sustainable source is increasingly recognized for its exceptional natural properties. To effectively harness convert energy, the development advanced materials imperative. Porphyrins, renowned their role light-harvesting antennas in nature, play photosynthesis. In this study, CuTCPP/g-C3N4 heterojunction photocatalyst was synthesized through combination electrostatic self-assembly situ growth methods. composite exhibited photostability remarkable efficiency photocatalytic degradation methylene blue (MB). Specifically, 0.5% demonstrated an impressive rate 97.20% MB under simulated sunlight, which almost double that g-C3N4. Additionally, capabilities hydrogen production, generating 350.00 μmol g–1 just 2 h, 8.33 times higher than produced by further elucidate performance composite, photoelectrochemical techniques were employed to confirm charge transfer path validate effective electron–hole separation mechanism within heterostructure. Overall, these investigations significantly enhanced overall reaction. findings study underscore immense application potential nanocomposites artificial photosynthesis, environmental pollution control, clean conversion. Moreover, they reveal novel technical insights address global challenges future.
