摘　　要：采用孔径大小可控的阳极氧化铝模板通过热分解四硫代钼酸铵((NH4)2MoS4)前躯体制备二硫化钼纳米管阵列。对制备二硫化钼纳米管利用 SEM, TEM, HRTEM 和 ED 表征。结果显示,除去氧化铝模板后得到的二硫化钼纳米管排列整齐,并呈分支状。纳米管的形状和尺寸与相应的模板孔洞的形状和孔径保持一致。二硫化钼纳米管呈竹节状,且在节处是封闭的。MoS2 nanotubules were synthesized through thermal decomposition of ammonium thiomolybdate precursor ((NH 4 ) 2 MoS 4 ) by anodic aluminum oxide (AAO) template with controllable diameter of pores. The as-synthesized MoS 2 nanotubules were characterized by SEM, TEM, HRTEM and ED. Results show that the MoS2 nanotubules are multi-branched and well-ordered close paced after carefully etching away the template. The shape and size of the nanotubules agree well with those of template pores. The so-called bamboo-like morphology is obtained and the nanotubules are closed in sections.
