今天給大家分享的是20158月份《RSC Advances》上發表的一篇名為:L-asparagine-assisted synthesis of flower-like -Bi2O3 and its photocatalytic performance for degradation of 4-phenylphenol under visible-light irradiation

文章摘要如下:

Synthesis of nanosized -Bi2O3 on a large-scale is a great challenge due to its metastable state. A facile L-asparagine-assisted reflux-calcination route was successfully developed for the large-scale preparation of -Bi2O3 micro/nanostructures under mild conditions (low temperature, atmospheric pressure, and wide temperature window). The composition, phase structure, morphology, surface area, and photoabsorption properties of as-synthesized -Bi2O3 and its precursor were systematically characterized. The phase transformation conditions and possible formation mechanism of flower-like -Bi2O3 were discussed. It is found that with a simple reflux process at 100 C under atmospheric pressure, uniform monodisperse bismuth-asparagine complex microspheres with average diameters of ~500 nm were produced, then flower-like -Bi2O3 micro/nanostructures were conveniently obtained after calcining the precursor at temperatures ranging from 340 to 420 C. A surface CO32- coordination effect introduced from L-asparagine was explained the formation of stabilized -Bi2O3 at low temperature (up to 420 C). The as-synthesized -Bi2O3 shows excellent photocatalytic activity toward the degradation of 4-phenylphenol under visible-light irradiation, which is 3.7 and 21.4 times faster than the removal rates of -Bi2O3 nanospheres and a commercial -Bi2O3, respectively, and allows for the elimination of 93.2% total organic carbon after 60 min of irradiation. In addition, the photogenerated reactive species were identified by radical scavenger experiments and electron paramagnetic resonance spectroscopy, then a possible visible-light-induced photocatalytic mechanisms was proposed.
