Metal nanoparticle (NP) cocatalysts are widely investigated for their ability to enhance the performance of photocatalytic materials; however, practical application is often limited by inherent instability under light irradiation. This challenge has catalyzed interest in exploring high-entropy alloys (HEAs), which, with increased entropy and lower Gibbs free energy, provide superior stability. In this study, 3.5 nm-sized noble-metal-free NPs composed a FeCoNiCuMn HEA successfully synthesized. With theoretic calculation experiments, electronic structure augmenting catalytic CO

Abstract To effectively remove pharmaceuticals, nitroaromatic compounds, and dyes from wastewater, an efficient multifunctional material was created based on silver nanoparticles (Ag) MIL-125-NH 2 (MOF) immobilized viscose fibers (VF) as a support substrate. Firstly, were the surface of via in situ synthesis using trisodium citrate (TSC) reducing agent to create (VF-Ag). Then, VF VF-Ag decorated with titanium metal–organic framework VF-MOF VF-Ag-MOF.

This work presents the effect of Cu loading, using incipient wetness impregnation method, on sustainably synthesized MIL-100(Fe), NH2-MIL-53(Al), Zr-BDC and NH2-Zr-BDC MOFs their photocatalytic removal efficiency target dye, rhodamine B (RhB), from aqueous solutions. Several ratios have been tested, finding that 2 wt% load becomes optimum in terms metal distribution catalytic performance. Powder X-ray diffraction patterns (XRD) showed no difference parent supports case NH2-MIL-53(Al) Zr-BDC, whereas extra peaks are induced by NH2-Zr-BDC. In addition, several techniques indicate strongly interacts with MOF Cu@NH2-Zr-BDC, exhibiting lowest bandgap series, photoluminescence intensity a notable predominance oxidation state 2+. The above evidences lead Cu@NH2-Zr-BDC to behave as most effective catalyst RhB, reaching high 93 %, being able efficiently selectively remove basic dyes mixed samples, such RhB MB, but not for acidic like MO, also showing very good performance (46 % photodegradation) real waste water Hawassa textile factory, Ethiopia.
