Abstract The treatment of nanofiltration concentrate has always been a critical technical challenge in the application membrane technology for landfill leachate treatment. This study attempts to address this using electrocatalytic oxidation technology. A Pt‐modified Ti/RuO 2 ‐IrO anode was synthesized solution method. results show that Pt uniformly dispersed within Ru‐Ir composite oxide phase, and doping induced formation numerous disordered mismatched lattices on electrode coating surface. interaction between RuO system can enhance stability ternary electrode, improve electron transport efficiency, reduce surface resistance coating, thereby increasing efficiency chemical reactions. In leachate, it found under conditions current density 20 mA·cm −2 , distance 0.5 cm, pH = 5, removal rates COD, TOC, NH 4 + ‐N were 93.5%, 46%, 98% respectively, with an energy consumption only 0.66 kWh·(kg TOC) −1 . After repeated experiments, ‐Pt 8% also demonstrated good catalytic activity.

Core–Shell Magnetic Particles: Tailored Synthesis and Applications

Chemical Reviews, Год журнала: 2024, Номер unknown

Опубликована: Дек. 27, 2024

Core–shell magnetic particles consisting of core and functional shells have aroused widespread attention in multidisciplinary fields spanning chemistry, materials science, physics, biomedicine, bioengineering due to their distinctive properties, tunable interface features, elaborately designed compositions. In recent decades, various surface engineering strategies been developed endow them desired properties (e.g., hydrophilicity, roughness, acidity, target recognition) for efficient applications catalysis, optical modulation, environmental remediation, etc. Moreover, precise control over the shell structure features like thickness, porosity, crystallinity compositions including metal oxides, carbon, silica, polymers, metal–organic frameworks (MOFs) has as major method exploit new materials. this review, we highlight synthesis methods, regulating strategies, engineering, core–shell past half-century. The fundamental methodologies controllable with diverse organic, inorganic, or hybrid compositions, morphology, property are thoroughly elucidated summarized. addition, influences conditions on physicochemical dispersibility, stability, stimulus-responsiveness, functionality) also discussed provide constructive insight guidelines designing specific applications. brand-new concept "core–shell assembly chemistry" holds great application potential bioimaging, diagnosis, micro/nanorobots, smart catalysis. Finally, remaining challenges, future research directions predicted proposed.
