Description

一种多级结构ZnO@Au@ZIF-8复合光电极的构筑及应用
技术领域
本发明属于储能电极材料的技术领域，技术涉及金属氧化物、贵金属(Au)与金属有机骨架材料(MOFs)构筑的多级结构材料，特别是基于ZnO纳米棒阵列修饰贵金属(Au)并进一步原位生长MOF的构筑。
背景技术
能源消耗和环境恶化己成为阻碍经济和社会发展的障碍之一。太阳能作为一种可以替代不可再生资源(如煤、石油、天然气等)的重要清洁能源引起了人们越来越多的关注，其中以半导体金属氧化物(TiO2、SnO2和ZnO)作为光电极材料用于光电催化体系能够有效的实现太阳能到电能或化学能的转化。这主要是由于它们具有价格优廉，稳定性好和环保无毒等优点。但是该类材料其较宽的能带结构仅仅对可见光具有响应，且对可见光吸收较低，进而极大限制了其光催化效率。因此，如何探索和开发新型光催化剂成为人们研究的热点。
金属有机骨架材料(MOFs)是由金属离子或离子簇和有机配体通过配位作用构筑的多孔骨架材料。由于MOFs自身的比表面积及孔隙率高、孔径及孔表面性质的可调性，其在吸附分离、催化、能源存储等领域都具有潜在的应用价值。近年来，多孔MOFs及衍生物逐渐被应用到电化学储能与转换领域，例如锂离子电池、燃料电池及光电分解水装置等。此外，前人报道部分MOFs作为光电极材料可有效用于光电催化分解水体系。但是MOFs自身易于团聚，导致活性位点流失和催化活性下降。此外，MOFs相对较低的导电性同样抑制了其在光电催化体系中的应用。
发明内容
本发明的目的在于提供了一种在FTO导电玻璃基底生长多级结构ZnO@Au@ZIF-8光电极及制备方法。

本发明的内容主要分为三步：第一步是在FTO基底上通过简单的水热反应生长ZnO纳米棒；第二步是将通过甲醇还原制得Au纳米颗粒溶液；第三步是将ZnO纳米棒负载Au纳米颗粒且同时生长MOF构筑了多级结构的ZnO@Au@ZIF-8复合电极。
本发明上述复合材料的合成方法，包括以下步骤：
第一步分别用丙酮、乙醇和水超声对FTO预处理，通过简单水热法制备ZnO，具体方法：其将醋酸锌溶于无水乙醇制备5-10mM的醋酸锌乙醇溶液，将上述醋酸锌乙醇溶液旋涂到预处理的FTO上得到一层晶种薄膜，然后在300-400℃下退火30分钟；将生长ZnO晶种的FTO斜搭在含有相同摩尔浓度的30-60mM硝酸锌和30-60mM环六亚甲基四胺溶液的聚四氟乙稀反应釜中，反应温度80-95℃，反应时间5-24小时，冷却至室温，制得的ZnO电极用去离子水冲洗后在空气中干燥。
第二步配置B溶液，具体步骤是将四水合氯金酸溶解到甲醇和水的混合溶剂中，将混合溶液加热至50-80℃搅拌1-3小时至棕红色合成B溶液，每0.01-0.1g四水合氯金酸对应15ml甲醇和100ml水；
第三步将ZnO电极浸入母液C中进行水热反应，母液C是2-甲基咪唑溶水溶液和第二步B溶液的混合溶液；水热反应温度保持60-80℃，优选70℃，时间0.5-3小时，优选1小时。
母液C优选每1.5-3.0g 2-甲基咪唑对应10ml水，并对应10ml B溶液。
