采用葡萄糖水热法合成的密堆积碳质球模板制备了大孔SnO2。通过 XRD 和 FE-SEM 评估了大孔 SnO2 的结构和形貌。大孔SnO2的平均孔径约为190 nm，壁厚小于10 nm。采用碳填充大孔SnO2作为锂离子电池负极材料时，循环70次后容量约为380mAh g−1。循环性能的改善归功于碳基质，它被用作有效的物理缓冲剂，以防止分散良好的大孔 SnO2 塌陷。
The macroporous SnO2is prepared using close packed carbonaceous sphere template which synthesized from glucose by hydrothermal method. The structure and morphology of the macroporous SnO2are evaluated by XRD and FE-SEM. The average pore size of the macroporous SnO2is about 190 nm and its wall thickness is less than 10 nm. When the macroporous SnO2filled with carbon is used as an anode material for lithium-ion battery, the capacity is about 380 mAh g−1after 70 cycles. The improved cyclability is attributed to the carbon matrix which is used as an effective physical buffer to prevent the collapse of the well dispersed macroporous SnO2.
