電化學技術在清淨能源應用中扮演重要的角色。藉由電化學反應，能夠將電能轉換為如氫氣等化學能，也可以用於超級電容器和電池等儲電元件。此外，電化學反應也可用於生物或環境樣品的化學感測。因此，開發高活性的電極表面修飾材料至關重要。本實驗室的研究著重在設計、合成與鑑定各種先端孔洞材料，主要聚焦在金屬有機骨架(MOF) - 一系列具有超高比表面積、分子尺度上可調節的多孔結構和孔內化學官能基的高度多孔材料。目前實驗室主要研究方向：

(1) 具水穩定性之MOF材料之合成、鑑定與後修飾，並探討其電子與離子之傳導能力以及基本電化學或電催化特性。

(2) 設計由具水穩定性之MOF與具導電性之奈米碳材或導電高分子所組成之奈米複合材料，並探討其在電化學相關之應用。

(3) 以高結構強度之MOF作為模板，用以限縮觸媒或半導體之尺寸，進而應用於催化與化學感測器等用途。

The development of clean energy has gained more and more attention in recent years, and electrochemical technologies play an important role in a range of clear-energy applications. By utilizing electrochemical reactions to convert electricity into chemical energy (or vice versa), hydrogen gas or other useful fuels can be produced from water or other less valuable regents such as carbon dioxide, and the electricity can be stored in rechargeable devices such as supercapacitors and batteries. In addition, electrochemical reactions are also useful for selective chemical sensing of biological or environmental samples. The design and synthesis of highly active electrode materials, namely, the active thin film modified on the electrode surface that can facilitate the desired electrochemical reaction, are thus crucial for the development of high-performance electrochemical devices toward energy and environmental applications. 

The Kung Research Group at NCKU aims to design and synthesize the nanoporous materials with high electrochemical activities for the applications in electrochemical energy conversion, supercapacitors, and electrochemical sensors. Our main research efforts focused on metal–organic frameworks (MOFs) – a series of highly porous materials with ultrahigh specific surface area, tunable pore structure in the molecular scale, and tunable chemical functionality within the nanopores. The research directions in our group include:

(1) The fundamental study on the charge conduction and ionic transport within MOF-based materials during electrochemical operations

(2) The design of high-performance MOF-based composite materials 

(3) The use of pore confinement in MOFs for designing highly active catalysts
