Polypyrrole-Fe2TiO5 composites for adsorption and photocatalytic degradation of micropollutants
In this paper, a new series of Fe2TiO5 - polypyrrole (FTO-xP) were prepared by the facile polymerisation method using sulphuric acid and hydrogen peroxide as oxidising agents. The synthesised compounds were characterised by diffuse reflectance spectroscopy (DR/UV–vis), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), microscopic analysis (SEM) and specific surface area analysis (BET) to evaluate their optical and surface properties, morphology, phase composition and crystallinity. The new composites were used for photocatalytic removal of micropollutants: highly toxic Cr(VI) and ibuprofen (IBU). The effect of polypyrrole content in the composite on the efficiency of selected micropollutants degradation was investigated. The results showed that FTO-xP composites had better adsorption capacity and photocatalytic activity than single components. Hybrid FTO-xP composites could efficiently remove inorganic/organic micropollutants in the aqueous phase.
期刊介绍：
The aim of Advanced Powder Technology is to meet the demand for an international journal that integrates all aspects of science and technology research on powder and particulate materials. The journal fulfills this purpose by publishing original research papers, rapid communications, reviews, and translated articles by prominent researchers worldwide.
The editorial work of Advanced Powder Technology, which was founded as the International Journal of the Society of Powder Technology, Japan, is now shared by distinguished board members, who operate in a unique framework designed to respond to the increasing global demand for articles on not only powder and particles, but also on various materials produced from them.
Advanced Powder Technology covers various areas, but a discussion of powder and particles is required in articles. Topics include: Production of powder and particulate materials in gases and liquids(nanoparticles, fine ceramics, pharmaceuticals, novel functional materials, etc.); Aerosol and colloidal processing; Powder and particle characterization; Dynamics and phenomena; Calculation and simulation (CFD, DEM, Monte Carlo method, population balance, etc.); Measurement and control of powder processes; Particle modification; Comminution; Powder handling and operations (storage, transport, granulation, separation, fluidization, etc.)
