Tungsten oxide nanowire-reduced grapheneoxide aerogel for high-efficiency visible light photocatalysis, Carbon78(2014)38-48. 影響因子:6.16 摘要:A light, 3-D, porous aerogel was fabricated by way of a simple approach from 1-D tungsten oxide nanowires and 2-D reduced graphene oxide sheets. The as-prepared graphene oxide, tungsten oxide nanowires, and tungsten oxide-reduced graphene oxide (W18O49-RGO) aerogel were characterised. The photocatalytic activities of as-prepared aerogel under visible light irradiation were investigated through the degradation of six different organic dyes including Rhodamine B, reactive black 39, reactive yellow 145, weak acid black BR, methyl orange, and weak acid yellow G. In comparison with the pure W18O49 nanowires, the prepared W18O49-RGO aerogel had significantly improved photocatalytic efficiency. Also, the photocatalysis of W18O49-RGO aerogel maintained its efficiency after 30 cycles for each of the six dyes. The photocatalytic mechanism was studied by adding hole and radical scavengers: the results confirmed that the holes generated in W18O49-RGO aerogel played a key role in the visible light photocatalytic process. 摘要中文翻譯:通過一種簡單的方法用1-D的氧化鎢納米線和2-D的還原的氧化石墨烯片材制備了透光的,3-D的多孔氣凝膠。表征了預(yù)制備的氧化石墨烯、氧化鎢納米線,和氧化鎢-還原的氧化石墨烯氣凝膠(W18O49-RGO)。研究了預(yù)制備的氣凝膠在可見光照射下的光催化活性通過六種不同有機染料的降解包括羅丹明B,活性黑39,活性黃145,弱酸性黑BR,甲基橙和弱酸性黃G。與純的W18O49納米線相比,制備的W18O49-RGO氣凝膠顯著提高了光催化效率。W18O49-RGO氣凝膠的光催化作用在6種染料每種30次循環(huán)后扔保持它的效率。通過增加孔洞和游離基清除劑研究了光催化作用機理:結(jié)果表明在W18O49-RGO氣凝膠中產(chǎn)生的孔在可見光光催化進程中起到關(guān)鍵的作用。 如果想免費獲得該文獻可點擊鏈接http://www.tjdrfk.com/news/fdg.html 圖片5.jpg 圖片1.jpg 圖片2.jpg 圖片3.jpg 圖片4.jpg |
