科學神燈窺視奈米建築美學
The Aesthetics of Nanoarchitecture Revealed by Scientific Aladdin's Lamp
摘要
能源短缺和環境污染是21世紀最重要的兩個議題，其中氫能及儲能材料在綠色能源產業的發展中扮演極其重要的角色。合理地設計出高功效的觸媒，並降低成本以取得氫能是長期以來一個重大課題。近年來，建構異質結構之奈米材料被視為是獲得高效能觸媒的一個關鍵想法。在過去的30年中，催化劑科學見證了同步輻射X光實驗的蓬勃發展。透過結合其他傳統的鑑定技術，能更加了深入了解異質結構奈米材料在進行催化反應中的結構變化。更重要的是，同步輻射X光技術還提供了進行各種原位測量技術，發展出一個研究反應過程的動態特性和時間關聯性的一個有力的技術平台。本文將針對近幾年快速發展的異質結構奈米能源材料，就其鑑定方法與應用在能源轉換／儲存方面進行介紹。

Energy shortage and environmental pollution are important issues in the 21st century. Hydrogen energy and energy storage materials play an extremely important role in the development of the green energy industry. Designing efficient catalysts to obtain hydrogen energy in a lower cost has been a major issue for long. In recent years, construction of heterostructured nanomaterials is regarded as a key idea to obtain high-performance catalysts. During the last 30 years, catalyst science has witnessed an impressive flourish of synchrotron x-ray experiments. Combined with traditional characterization techniques, we can have a deeper understanding of structural evolutions in catalytic reactions with heterostructured nanomaterials. More importantly, synchrotron radiation X-ray technologies also provide a variety of in situ measurements, thus developing a powerful technical platform to study the dynamic properties and time-dependent reaction process. This article will summary the recent development of heterostructured energy nanomaterials and its related characterization techniques for applications of energy conversion and storage.
