摘要

孔洞結構材料的合成與應用在近年來受到廣泛的重視與發展，具有可調控的孔洞結構（表面積、孔洞大小、孔洞對稱性）以及不同組成分的材料陸續被提出，然而許多功能性中孔洞結構材料，如光電材料、電極材料及感測器材料等，卻受限為非晶型結構，而限制其在磁學、光學及電化學等儀器方面的發展與應用。許多專家學者致力於多成分及多功能性中孔洞結構複合材料的開發與應用，結合金屬或金屬氧化物來增加材料的新穎性與功能性。目前此類規則性中孔洞材料在各領域均展現出優越的應用特性，除具有規則型孔道與孔洞、高比表面積和孔洞體積的優點外，更因有連續可調控之孔洞大小與可進行表面官能基修飾等優點，不僅將分子篩由微孔洞擴展至中孔洞範圍，並可應用在藥物傳遞、催化反應、生物醫學以及鋰離子電池之電極材料上。本文將以碳－二氧化碳為例，介紹多功能週期性中孔洞材料的製備、特性鑑定所需儀器之原理與意義，同時討論此類結構性材料在環境與能源領域的可能應用。

The fabrication and application of porous materials have recently received considerable attention because of their tunable pore structures and versatile nanocomposites. However, the amorphous phase in functionalized mesoporous materials hampers the application of these materials in the fields of photoelectronics, electrochemistry and biosensors. Recently, several promising results related to the fabrication and characterization of multifunctional highly ordered mesoporous nanocomposites incorporating metals or metal oxides have been documented, which extend the possible application of these materials to drug delivery, biomedical sensing and lithium ion battery. In this text, the fabrication and characterization of highly ordered mesoporous nanocomposites will be introduced by using carbon-titanium oxide as an example. In addition, the use of this material as the sensing element for energy and environmental application will be discussed.
