, 2014 本實驗以兩階段水熱法合成CeO2─WO3核／殼奈米線與WO3─CeO2核／殼奈米棒，第一階段先合成出CeO2奈米線與WO3奈米棒核心結構，然後在核心奈米結構表面合成WO3與CeO2外殼。藉由中斷實驗，我們仔細觀察CeO2奈米線在成長過程的結構演變來討論其成長機制。合成產物的形貌、結構及組成是利用SEM、XRD、TEM觀察與分析。另外，我們也將四種奈米結構製成氣體感測元件並量測對CO與NO2的氣體感測特性。實驗結果顯示，CeO2奈米線的成長是利用Ostwald ripening （OR）的機制 ...

Catalytic Oxidation of CO and VOC in Flue Gas of Coffee Roasting Machines
Chemie Ingenieur Technik, EarlyView.Platinum‐coated cordierite monoliths effectively oxidized CO and VOC in coffee roasting exhaust with higher Pt loadings lowering light‐off temperatures. Scaled up 90 g/ft3 catalyst in a 5 kg roaster achieved 96% CO and around 78% VOC conversion at 350°C, highlighting stable operation requires flue gas temperatures ≥350°C.
