摘要
根据绿叶有利于光捕获精细分级结构以及氧化铜对可见光吸收能力强的特性,以C4植物中的玉米叶片作为模板,通过一步浸渍法结合煅烧工艺成功将其转变为CuO光催化功能材料。研究结果表明,CuO保留了原始玉米叶片的分级结构。具有叶片分级结构的CuO光催化性能得以明显改善:在可见光照射下,人造CuO叶子对甲基橙溶液的降解速率是无模板条件下合成CuO的2倍。其优异的光催化性能是其本身独特的精细分级结构和组分协同作用的结果。
Inspired by the hierarchical structures of green leaves and CuO with high light-harvesting capability,maize leaves were used as templates to generate artificial CuO leaves through soakage and calcination processes.Result showed that the prepared CuO inherited the hierarchical structure of the original maize leaves.The photocatalytic performance of CuO with leaf grading structure has been significantly improved.Under visible-light irradiation,the decomposition rate of the templated CuO was about two times of the rate of the contrasting sample.The higher photocatalytic activity of the templated CuO was probably attributed to the synergetic effect of the hierarchical structures and CuO properties.
