Bi nanosphere/GO composite was first synthesized by a simple one-step solvothermal method.Compared with bare Bi nanosphere,the nanohybrid exhibited highly enhanced and stable plasmonic photocatalytic activity towards removal of NO under 280nm light irradiation,resulting from the assistance of GO.Bi nanosphere acts as antenna for incident light and graphene oxide is regarded as an acceptor and transporter of the photogenerated electrons[1]by the surface plasmon resonance (SPR) of Bi[2] while providing binding sites for Bi deposition and NO adsorption.Furthermore,the related growth and photocatalytic mechanism of Bi/GO composite system was proposed reasonably.

采用第一性原理方法系统地研究了IrAl3四种不同晶体结构的结构稳定性、弹性性能、热力学性能和电子结构等性质.计算结果表明,这四种结构在基态下是热力学稳定存在的,但六方结构的IrAl3(空间群:P63/mmc)合金比其它三种结构稳定,在基态下的晶格参数与实验数据比较吻合.计算的晶格参数表明IrAl3沿着c-轴的抗压缩系数要强于沿着a-轴的抗压缩系数.尽管这四种IrAl3合金的体弹性模量和剪切模量要小
本文以Al-Zn-Mg和Al-Zn-Mg-0.25Sc-0.10Zr两种合金板材为研究对象,研究了Sc和Zr微合金化对Al-Zn-Mg合金板材的超塑性能的影响.结果表明Al-Zn-Mg合金在变形过程中,由于粗大的晶粒尺寸(大于10μm)和非常弱的微观结构热稳定性,不具有超塑特性.然而,Al-Zn-Mg-Sc-Zr合金在450～550℃和5×10-3～5×10-2 s-1下表现出优异的超塑特性(延伸
