(2)称取0.1g ZnIn2S4超声分散于1mL水中,加入0.1mol/L CoCl2·6H2O溶液2mL,搅拌5min,然后加入0.2mol/L NaH2PO2溶液7mL,在Ar气氛下搅拌30min,用300W氙灯做为光源光照5min,结束光照,混合溶液冷却至室温,离心洗涤至离子浓度<10ppm,60℃干燥12h,研磨,得到复合光催化剂CoxP/ZnIn2S4。
图1是负载CoxP前后ZnIn2S4样品的XRD图谱,由图可知,样品于2θ值为21.6°、27.7°、30.4°和47.2°等处出现的衍射峰,分别对应于六方晶型ZnIn2S4(JCPDS:89-3962)的(003)、(011)、(012)和(110)晶面,由2θ为27.7°的(011)晶面衍射峰的半峰宽算得ZnIn2S4的平均晶粒大小约为45.3nm,没有检测到CoxP的特征衍射峰,可能是由于CoxP的负载量太少而未达到仪器的检测限。
图2是实施例1制备的CoxP/ZnIn2S4样品的电镜以及能谱图,由图2(a)可知,CoxP/ZnIn2S4样品的形貌呈为纳米片组成的直径为2~5um的多级分层牡丹花状微米球状,样品表面出现颗粒状物质可能是CoxP堆积所致。通过高倍透射电镜图2(c)可以观察到ZnIn2S4的晶格条纹,其中间距为0.32nm的晶格条纹,对应于六方晶相ZnIn2S4的(011)晶面的面间距,而CoxP为非晶态,未观察到其晶格条纹。由能谱图2(d)可以看出样品含有Zn、In、S、Co和P五种元素。
图3是CoxP/ZnIn2S4样品的Mapping图,图3b、3c、3d、3e和3f分别显示样品表面Zn、In、S、Co、P等元素的分布情况,各元素的Mapping图都配色均匀,说明CoxP均匀地分布在ZnIn2S4表面。
实施例2
