Functional covalent triazine frameworks for catalysis and energy storage applications

在微观和宏观尺度上具有固有孔隙度的聚合物由于其独特的结构和优越的性能而引起了人们对各种功能应用的极大研究兴趣。共价三嗪框架（CTFs）是一类具有结构可调、化学稳定性高、杂原子含量丰富等特点的多孔聚合物，通常是由芳香族腈三聚合成的。这项提议的DG研究的总体目标是开发和设计一系列新的功能CTFs，这些CTFs具有可调的定义良好的结构/功能和卓越的性能，可用于催化和储能领域。确定了三个具体项目：(1)开发CTFs作为pd基烯烃聚合催化剂的新型三维大分子配体；(2)开发烃类半加氢非均相功能ctf负载Pd纳米催化剂；(3)开发CTF纳米复合锂离子电池负极材料。

Polymers with intrinsic porosity in both the micro- and macroscopic scale have aroused enormous research interest for a variety of functional applications because of their unique structures and resulting superior properties. Covalent triazine frameworks (CTFs), synthesized often by trimerization of aromatic nitriles, are an exciting class of porous polymers with tunable structure, high chemical stability, and rich heteroatom contents, which facilitate their emerging applications in various fields. The overall objective of this proposed DG research is to develop and design a novel range of functional CTFs of tunable well-defined structures/functionalities and superior performance properties for applications in catalysis and energy storage areas. Three specific projects are defined: (1) developing CTFs as novel 3D macromolecular ligands for Pd-based olefin polymerization catalysts; (2) developing heterogeneous functional CTF-supported Pd nanocatalysts for semi-hydrogenation of alkynes; (3) developing CTF nanocomposite anode materials for lithium-ion batteries. The proposed research is highly multidisciplinary in nature and combines diverse disciplines including polymer chemistry and physics, nanotechnology, materials science, catalysis, and energy storage techniques. It is expected that this research will lead to a novel class of CTF materials of tailored structures and superior performance properties, which may find value-added applications in catalysis and energy storage areas. The fundamental knowledge to be generated in this research will also contribute significantly to the design and synthesis of porous polymer materials, catalysis materials, and energy storage materials, and broaden the understanding of the structure-performance relationships. Moreover, the proposed research will also offer valuable opportunities for the training of next-generation researchers for Canadian universities, industries, and government research laboratories.
