銀和鈀修飾二氧化錳/二氧化鈦光電極光催化性能研究
發(fā)布時間：2020-12-09 02:35
直接利用太陽能為光源的TiO2光催化技術(shù)被認(rèn)為是21世紀(jì)最具應(yīng)用前景的環(huán)境治理技術(shù)之一,它既解決了能源危機的困擾,又滿足了污染防治的迫切需要。與薄膜電極相比,陽極氧化法制備的TiO2納米管陣列（TiO2 NTs）因具有較高的比表面積、獨特的尺寸效應(yīng)和良好的光吸收性能,在太陽能轉(zhuǎn)換、光解水制氫和污染物去除領(lǐng)域得到了廣泛關(guān)注。然而,TiO2對可見光利用效率較低,不能有效利用太陽能。本論文在制備高度有序的TiO2 NTs基礎(chǔ)上,通過MnOx改性獲得具有可見光響應(yīng)的復(fù)合TiO2光電極,并對其物理化學(xué)結(jié)構(gòu)、光電化學(xué)性能和光電催化學(xué)性能進(jìn)行了系統(tǒng)研究,以期為二氧化鈦光催化氧化技術(shù)處理廢水中難降解有機物的實用化提供依據(jù)。為解決粉末態(tài)催化劑不易回收、難重復(fù)使用的問題,本文采用電化學(xué)陽極氧化法以鈦片為基底原位制備TiO2 NTs,研究四種不同類型的電解質(zhì)溶液（NH4）2SO4<...
