實驗一 利用吸附沉積法制備活性碳錳氧化物超電容之研究 實驗一以活性碳的表面吸附過錳酸鉀,再與加入反丁烯二酸反應,使粉體在成核的同時達到催化及分散的效果。以減少氣體的產生率及粉末堆積的問題。所以本實驗乃以水溶解過錳酸鉀的過程中加入不同比例之活性碳,待溶解過後再加反丁烯二酸而得到我們的錳氧化物。再經由DTA-TGA取得所需要熱處理溫度,以FTIR、EPR得知其鍵結的變化,以XRD確定其結構,以TEM觀察其表面形貌,以SEM觀察表面形貌及成分分佈。所得的結果添加活性碳後的電容值先降後升,熱處理完後的結果亦同,但電容值明顯比未熱處理前低。 實驗二 酒精製備氧化錳超電容之研究 由實驗一的實驗數據發現,活性碳確實發揮催化的效果。但其分散的效果卻沒有產生。故實驗二係直接改變反應物的方式改變氧化錳的製程。而本實驗就是以過錳酸鉀加入酒精以代替過去使用的反丁烯二酸並以HCl及NaOH來調控其酸鹼值並比較其反應後的各種性質。其結果顯示於弱酸弱鹼中的確有助於電容值之提升。
Experiment one using the active carbon as an absorbent for Manganese oxides supercapacitors. Experiment one: using active carbon absorb potassium permanganate. Then acceding the Fumaric acid to make our Manganese oxides. Then using the DTA-TGA to fine the heat treatment temperatures. Then the atomic bonding of the Manganese oxides are estimated by FTIR and EPR. And using the XRD to fine the crystalline structure. using the TEM and SEM to estimate the grain size. The more active carbon the higher capacitive. But only acceding a little active carbon the capacitive will be descend. Experiment two: using the alcohol to make our Manganese oxides supercapacitor. In this experiment we use the alcohol to replace the Fumaric acid and using the NaOH and HCl to control the pH number. The result if only acceding a little acid or a little alkali will promote the capacitive.
