Removal of rhodamine B from aqueous solution by BiPO

Lei LI, Jian XU, Changsheng GUO, Yuan ZHANG

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 3,   Pages 382-387 doi: 10.1007/s11783-013-0504-5

Abstract: Hexahedron-like BiPO microcrystals were sucessfully synthesized via a template-free hydrothermal method. The resulting samples were characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and UV–vis spectroscopy. The BiPO samples were of pure monoclinic phase, and the initial amount of during synthesis did not show obvious effect on the phase properties of the materials. The hexahedron-like BiPO microcrystal had explicitly cut edges, and its thickness was about 1 μm. The photocatalytic performance of the BiPO catalysts was evaluated by photodegradation of RhB under UV light irradiation with commerial Degussa P25 TiO as reference. Compared with P25, the BiPO catalysts displayed higher photocatalytic activity, with 98.7% of RhB degraded during 60-min experiment. Cost evaluation analysis was adopted to describe the energy consumption of the degradation process, and the results suggested the potential application of this material in the field of dye-contaminated wastewater treatment or environmental matrices remediation.

Efficient dechlorination of 2,4-dichlorophenol in an aqueous media with a mild pH using a Pd/TiO

Jiangkun DU,Jianguo BAO,Wei HU

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 5,   Pages 919-928 doi: 10.1007/s11783-015-0794-x

Abstract: In this study, palladium-loaded titania nanotubes was fabricated on a titanium plate (Pd/TiO NTs/Ti) for efficient electrodechlorination of 2,4-chlorophenol with a mild pH condition. The nature of Pd/TiO NTs/Ti electrodes was characterized by field-emission scanning electron microscope (FESEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and cyclic voltammetry (CV) techniques. The characterization results indicated the generation of Pd nanoparticles which were evenly dispersed on titania nanotubes arrays on the Pd/TiO NTs/Ti surface. An effective degradation efficiency of up to 91% was achieved within 60 min at cathode potential of −0.7 V ( SCE) and initial pH of 5.5. The effects of the applied cathode potential and initial pH on the degradation efficiency were studied. A near neutral condition was more favorable since very low and very high pHs were not conducive to the dechlorination process. Furthermore, the intermediates analysis showed that the Pd/TiO NTs/Ti electrode could completely remove chlorine from 2, 4-dichlorophenol since only phenol was detected as the byproduct and the concentration of released chlorine ions indicated near-complete dechlorination. This work presents a good alternative technique for eliminating persistent chlorophenols in polluted wastewater without maintaining strong acidic environment.
