【摘要】 采用溶胶-凝胶法制备了纳米介孔二氧化锡,并利用扫描电镜、透射电镜、X-射线衍射等分析手段对纳米介孔二氧化锡进行了表征。对氧化铟锡（ITO）/SnO₂电极进行了光电信号的检测,研究了草酸钾、三乙醇胺两种电子供体和CdS量子点对ITO/SnO₂电极的光电行为的影响。结果表明:电子给体三乙醇胺与CdS量子点对介孔SnO₂薄膜具有明显的光电增强作用。更多还原

【Abstract】 Mesoporous SnO₂ nanomaterial was prepared through sol-gel method in the present work,and was characterized by transmission electron microscope（TEM）,scanning electron microscope（SEM）and X-ray Diffractometer（XRD）.The photoelectrochemical behavior of indium tin oxide（ITO）/SnO₂ electrode was studied,and the effect of potassium oxalate,triethanolamine and CdS quantum dots on the ITO/SnO₂ electrode was discussed.It was found that triethanolamine and CdS quantum dots could enhance the photocurrent signal of ITO/SnO₂.更多还原
