近五年的研究主題可以概分為:
- 燃料電池的電極觸媒研究:燃料電池是一種新世代潔淨能源,其中電能輸出效能與其價格取決於電極上的觸媒電催化作用,近年研究工作中開發了可以直接塗佈成為電極的白金奈米顆粒,可以簡化電極的製備步驟、同時可以有效的降低電極白金用量,具商業應用價值;另一項研究成果為開發電極觸媒的活性鑑定方法,可以在觸媒製成氣體擴散電極前就能進行活性篩檢,預期此活性篩檢方法有機會成為燃料電池觸媒研究開發的標準方法。
- 金觸媒的反應特性分析:金觸媒已被證實為具有極高的CO氧化活性,但由於金本身為鈍性金屬,有關金觸媒活性的構成原因是一個極為有趣的基礎研究課題。近年的研究已發表了有關金觸媒的CO氧化活性與CO+NO反應活性的對比分析、金觸媒製備敏感性分析、金觸媒對NH3氧化反應探討等,其中除了反應特性分析與一般觸媒特性鑑定之外,也運用同步輻射光源的EXAFS技術,來進行觸媒在製備過程、前處理過程與反應過程的結構變化分析。這些以發表與即將發表的文章,對於影響金觸媒活性的機理,有詳盡的分析探討,依據所得結果可以歸納出一個製備高活性金觸媒的基本原則。
- 甲醇縮合反應的測試與觸媒開發:甲醇價格一直相當低廉,製備方法可以不需倚賴石油為原料,故有可能是替代石油的新能源。文獻中的甲醇應用主要在於直接甲醇燃料電池與甲醇製氫,有許多的相關文獻發表。本研究室根據文獻資料推論,甲醇應該也可以經過縮合反應製作高碳數含氧官能基化合物(oxygenates),目前在實驗室中已開發出一種新的銅觸媒,可以催化此甲醇縮合反應合成路徑,此路徑的確定將可以使甲醇能完整替代石油,兼作為能源供應與化學品供應的雙重角色;此工作已獲准美國專利。
- 功能性無機奈米結構材料製備:運用文獻中所累積的奈米材料製備方法,加以修改與調整以製備適合於觸媒應用的材料,例如可以直接塗刷製作電極的白金奈米顆粒,可以控制孔洞大小的陣列孔洞碳膜片等,都是近年研究所探討的項目。
