高度有序二元纳米阵列的可控制备及其电催化还原二氧化碳应用

复合纳米材料在电催化应用中具有非常重要的意义。但是杂乱无章的复合纳米材料存在材料的催化性能低及稳定性差等问题导致应用受限。本项目针对这些问题，提出以有序模板为基底，构筑高度有序二元复合纳米材料阵列结构，通过模板的孔道结构高度控制复合材料的形貌及结构。利用二元复合材料之间的耦合协同作用，以及高度有序阵列结构的大比表面积和良好的电子传输性能，构筑具有高电催化活性、产物选择性及稳定性的电极。基于对阵列电极的形貌结构与电化学性能的研究进一步优化电极结构的设计与制备。本项目结合了高度有序二元复合纳米材料阵列的可控制备及高性能电极材料设计，为功能纳米材料的设计提供了新的思路。

The development of composite nanomaterials is very meaningful for electrocatalyst. However, the random composite nanomaterials suffer from low catalytic activity and poor stability, and so forth, have limited its application. To circumvent these obstacles, this project will construct highly ordered binary nanoarrays based on ordered template. The morphology and structure for each of the composite could be precisely adjusted by the control of template channel. It can develop an impressive electrode with high electrocatalytic activity, high product selectivity and good stability by utilizing the synergistic effect between two composite nanomaterials, large surface area and rapid electron transport stem from highly ordered arrays. Based on the marching relationship between the materials' microstructure and electrocatalytic performance to further optimize the design and fabrication of electrode. Furthermore, this project combined controllable fabrication of highly ordered binary nanoarrys and design of high-performance electrode materials, which will provide a new insight on constructing function nanomaterials.
