摘要：
Bismuth silicate Bi2SiO5 (BSO) nanoparticles were synthesized through a hydrothermal reaction followed by heat treatment. Kinds of characteristic methods were employed to study the phase, morphology and photophysical properties of BSO. The as-prepared BSO exhibited high photocatalytic activity and good photodegradation repeatability in the decomposition of Rhodamine B (RhB) dyes under simulated sunlight irradiation. The experimental results by using different scavengers demonstrate that the photogenerated h(+) and e(-) radicals play an interactional role in the degradation of RhB dyes. BSO nanocrystals could be a promising photocatalysis in water purification industry. Crown Copyright (C) 2013 Published by Elsevier B.V. All rights reserved.
