By a News Reporter-Staff News Editor at Ecology, Environment & Conservation -- Current study results on Photocatalytics have been published. According to news reporting originating from Nanchong, People's Republic of China, by VerticalNews correspondents, research stated, "Three-dimensional (3D) hierarchical porous architectures have become promising candidates for adsorption-based environmental remediation in recent years. However, such type of adsorbents often suffers from the complicated production and undesirable regeneration, limiting their practical environmental application greatly."
Our news editors obtained a quote from the research from the College of Chemistry and Chemical Engineering, "In this contribution, a novel adsorbent based on hierarchical porous bismuth oxyiodide (BiOI) architectures combining the highly effective adsorption and green photocatalytic regeneration were designed and fabricated by a facile and rapid microwave nonaqueous route. The resultant samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), nitrogen adsorption-desorption measurements, and UV-vis diffuse reflectance spectroscopy (DRS). The BiOI architectures displayed remarkable performance towards removal of Congo red (CR) from aqueous solution, showing a maximum adsorption capacity reached up to 216.8 mg g(-1). The kinetics and equilibrium of adsorption process were found to follow the pseudo-second-order kinetic and Freundlich isotherm models, respectively."
According to the news editors, the research concluded: "More importantly, the BiOI architectures were not only easy to separate from the reaction system because of the hierarchical structure and large sizes, but also attractive to photocatalytic regeneration due to their intrinsically prominent photoresponse in visible light region."
