【摘要】 以Zn(NO3)2·6H2O,Al(NO3)3·9H2O,Y(NO3)3·6H2O和Na OH为原料,采用溶液法制备了Al-Y共掺杂Zn O光催化剂(Al-Y/Zn O),并用X射线衍射(XRD)、扫描电镜(SEM)考察了Al,Y共掺杂对Zn O纳米棒形成及形貌的影响。结果表明,Al-Y共掺杂对Zn O晶粒大小基本没有影响,但会严重抑制Zn O纳米棒的生成,促使碱式硝酸锌(Zn5(OH)8(NO3)2·2H2O)的生成。以甲基橙(MO)为模型污染物考察了Al-Y共掺杂对Zn O纳米棒光催化活性的影响。结果发现,适量的Al-Y共掺杂会显著提高Zn O纳米棒的光催化活性。更多还原

【Abstract】 The( Al-Y)-codoped Zn Ophotocatalyst was prepared by a solution method with zinc nitrate hexahydrate( Zn( NO3)2·6H2O),aluminum nitrate nonahydrate( Al( NO3)3·9H2O),yttrium nitrate hexahydrate( Y( NO3)3·6H2O) and sodium hydroxide( Na OH) as raw materials. The effect of( Al-Y)-codoping on the formation and morphology of Zn Onanorod was studied by X-ray diffraction( XRD) and scanning electron microscopy( SEM). The results show that the( Al-Y) co-doping has little effect on the Zn Oparticle size,however it restrains the formation of the Zn Onanorod,and promotes the formation of zinc hydroxide nitrate( Zn5( OH)8( NO3)2·2H2O). The effect of( Al-Y) co-doping no the photocatalytic activity of Zn Onanorod was evaluated by photodegradation of methyl orange( MO). The results indicate that an appropriate amount of( Al-Y) co-doping could remarkably improve the photocatalytic activity of Zn O.更多还原
