Description
技术领域
本发明属于燃料电池技术领域，具体涉及一种负载金属纳米颗粒的共轭微孔高分子电催化剂及其制备方法和在直接醇类燃料电池中的应用。
背景技术
由于不可再生能源的广泛消费和日益严重的环境污染问题，对清洁可再生能源的需求也日趋增加。直接醇类燃料电池以其醇类燃料的广泛可用性、比氢燃料电池更方便的储存和运输以及环境友好而备受关注。而大量研究证实，钯(Pd)基电催化剂以其来源丰富、耐久性好等优势，已被证明是直接醇类燃料电池阳极电催化剂最有希望的替代品之一。但是，Pd基电催化剂仍存在许多缺陷，如电极表面中毒、化学活性低、Pd纳米粒子易团聚等。为了克服上述障碍，调控界面效应来调控负载型Pd催化剂被认为是一种有效的策略。界面效应不仅通过金属与载体之间形成良好的共价键来控制金属纳米粒子的分散和稳定，而且通过电子转移可引起电荷的重新分布。电荷再分布可调节负载金属的d带结构，降低了能垒，还能促进速率限制步骤，提高电催化活性。
近年来，科研人员研究了杂原子在载体中对界面效应的影响，如氮掺杂碳纳米管、硼氮掺杂多孔碳、氮硫掺杂石墨烯、氮硫共掺杂碳纳米片，掺杂氮、硫、硼等杂原子是一种由于碳材料电子结构变化而暴露其表面活性位点从而提高其电化学性能的有效方法。然而，传统的Pd基类杂原子掺杂碳基催化剂的载体是通过高温热解、水热合成、溶剂热合成等方法制备获得，很难在碳基催化剂载体中生成单一类型活性位点，这限制了对活性位点的深入了解。
发明内容
本发明的目的是：提出采用杂原子界面工程策略可控性调节催化活性位点，设计合成一类无碳化、结构可调、活性位点可控的共轭微孔高分子催化载体材料，通过负载金属来开发高效的直接醇类燃料电池催化材料体系。
为了实现上述目的，本发明的技术方案如下：

其中，选自如下结构中的一种：
其中，X为O、S、Se、Te中的任一种；R为H或C1～C40的或支链或烷氧链或氟代烷基链。
进一步的，所述为/>
进一步的，所述金属为钯、银、镍、锌或钴。

所述金属化合物为氯化钯、氯化银、氯化镍、硝酸锌或硝酸钴。
进一步的，所述原料2为2,5-二溴噻唑、2,5-二溴呋喃、2,5-二溴噻吩、2,5-二溴吡啶或1,4-二溴苯。

本发明的技术方案与现有技术相比，具有以下优势：
(1)利用共轭微孔高分子作为金属基催化剂载体，避免了传统方法中高温热解、水热合成等费时费力的合成方法，本发明合成方法环保绿色，安全性好，可重复性高。
