Microplastics (MPs) and other organic matters in textile wastewater have posed a formidable challenge for treatment processes, particularly the primary stages such as ultrafiltration (UF). UF plays crucial role preventing entry of pollutants into subsequent steps. However, performance efficiency membranes is compromised by potential fouling membrane pores MPs, dyes bovine serum albumin (BSA). This study focuses on enhancing performance, specifically its antifouling properties, through development high-performance using MIL-53(Fe) metal-organic framework (MOF) particles (noted MIL-53 here). Various concentrations (0.05, 0.1, 0.2, 0.5 wt%) were integrated structure phase inversion process. Streaming zeta results confirmed negatively charged surface their high hydrophilicity was validated contact angle analysis. FTIR, SEM, EDS, XRD presence membranes. The developed tested 24 h to assess with 30-min hydraulic flush measure flux recovery ratios. Methylene Blue (MB) dye used cationic present evaluate removal synergistic effects rejection (i.e., MPs BSA). Since previous studies not fully addressed combination matter, this thoroughly investigated effect particle-type foulants interactions (MB), well water soluble protein-type (BSA) interaction MB. indicated that exhibited higher MB when either MP or BSA, along improved properties. optimised 0.1 wt% demonstrated nearly 96% BSA around 86% mixed foulant case (BSA-MB). modified substantial increase from 176 L m

Abstract A catalyst for the oxygen reduction reaction (ORR) based on metal‐organic framework material MIL‐53(Al) modified with palladium was synthesized. Its textural and morphological characteristics were studied using method of adsorption porosimetry, scanning electron microscopy (SEM), transmission (TEM), energy dispersive X‐ray analysis (EDAX), diffraction (XRD), Raman spectroscopy, photoelectron spectroscopy (XPS), thermogravimetric (TGA‐DSC). The electrocatalytic properties synthesized in ORR by voltammetry, a rotating disk electrode. Corrosion resistance CV mode. It found that is characterized high corrosion resistance. tolerance Pyr_MIL‐53(Al)_Pd to methanol studied. obtained membrane electrode assembly (MEA) formed spraying an ionomer suspension onto gas diffusion layer (GDL). Pyr‐MIL‐53 (Al)_Pd commercial platinum (60% Pt) (HiSPEC 9100) catalysts compared cathode composition, 10% PtM (M = Ni, Mo)/CNT used anode. power density FC (P) calculated current‐voltage curves. Based set characteristics, MIL‐53 (AL) doped superior efficiency catalyst.
