地球上最豐富的能源是太陽光。利用太陽能進行綠色能源生產(chǎn)和環(huán)境修復(fù),從根本上解決了能源安全和環(huán)境污染兩大難題。光電化學(xué)（PEC）是一種借助半導(dǎo)體材料,將太陽光轉(zhuǎn)化為可儲存的氫燃料的水分解技術(shù),是一種溫和、綠色、可再生的現(xiàn)代的技術(shù)。另一方面,盡管能源危機愈演愈烈,但環(huán)境污染問題的日益加劇又是當(dāng)前人類生存面臨的又一大威脅。眾多的環(huán)境污染中,水污染嚴重影響著地球上人類的日常活動,造成了嚴重的經(jīng)濟損失。因此利用可以吸收太陽光的半導(dǎo)體凈化廢水,是一種很有前景的污水處理技術(shù)。太陽能制氫和廢水處理新技術(shù)商業(yè)化的瓶頸在于其制造成本。PEC技術(shù)和廢水處理系統(tǒng)的成本主要取決于所使用的前驅(qū)體材料和制造方法。盡管一些低成本材料在太陽能水分解和廢水處理方面顯示出不錯的活性和穩(wěn)定性,但其制備方法復(fù)雜,價格昂貴以及無法大規(guī)模使用。在本文中,我們介紹了一種新穎且高效的原位燃燒方法,制備了具有低成本的三元氧化物材料MxVyOz（M=Bi,Cu）薄層光電極和新型多功能（PAN）/AgBr/Ag靜電紡絲纖維膜用于光催化以及廢水處理領(lǐng)域。首先,我們利用原位燃燒方法制備了釩酸鉍（BiVO4）光陽極。燃燒過程中的放熱反應(yīng)可以加速溶...
