在这项工作中，我们报告的多孔二氧化锡纳米线束的合成高产率，通过一个简单的解决方案的方法。该束由多孔SnO 2纳米线组成，其总直径在80-120 nm的范围内。通过调节Sn前驱体的剂量来控制样品形貌的生长。纳米线束的功能测试包括降解罗丹明B（Rh B）的光催化效果，以及作为锂离子电池阳极的电化学性能。电化学测试表明，所合成的产品显示出非常高的可逆容量和库仑效率在初始循环，以及合理的良好的循环性能相比，其他SnO 2纳米结构。这种简单廉价的方法合成的多孔SnO 2纳米结构有望在废水处理和/或能量存储方面具有应用潜力。
In this work, we report the synthesis of porous SnO2 nanowire bundles with high yield through a simple solution approach. The bundles are composed of porous SnO2 nanowires with overall diameters in the range of 80-120 nm. Growth control of the sample morphology is demonstrated by adjusting the dose of Sn precursor. Functional tests of the nanowire bundles include photocatalytic effect in the degradation of Rhodamine B (RhB), and electrochemical properties as a Li-ion battery anode. The electrochemical test reveals that the as-synthesized product shows a very high reversible capacity and Coulombic efficiency in the initial cycles, as well as reasonably good cycling performance compared with other SnO2 nanostructures. Such porous SnO2 nanostructures synthesized by the simple and cheap method are expected to have application potential in waste water treatment and/or energy storage.
