高壓汞燈可以用作二氧化鈦光催化光源嗎

問題描述：不全是，汞燈開的時候你能看見，說明里面必然有可見光，一切高于絕對0度的物體都會輻射紅外線的。一般來說300w和波長沒有必然聯系，因為300w只是一個輻射功率+系統損耗功率，即使是可見光輻射，也可以達到300w

回答(1).₅₀₁₀ ₁₃₃₃

回答(2).哥們 估計不行 二氧化鈦 能夠吸附 汞（原因如下） 你用了汞燈 必然會有汞被吸附 催化活性應該降低 華盛頓大學的化學工程教授帕瑞蒂姆·拜爾斯瓦 (Pra timBiswas)發明了一種除汞新方法 (美國專利號為6 2 4 82 17) ,將二氧化鈦作為吸附劑引入煙道氣中 ,可吸收98?汞 ,然后用常規的靜電沉降器即可將汞除去。拜爾斯瓦曾試驗了幾種含硅、鈣和鈦的吸附劑用于煙道氣中除汞。用模擬煙道氣 (有或沒有SO2 存在的情況下 )試驗這些吸附劑 ,發現硅基吸附劑無論在SO2 是否存在的情況下都不捕獲汞 ;氧化鈣能吸附煙道氣中 33?汞 ,但在有SO2 存在時吸附率大大降低 ;二氧化鈦的吸附效果最好 ,它對汞的捕獲率高達 88? 99?捕獲率與…

回答(3).先用紫外燈測試一下其在紫外光下的光催化性能，效果好的話再用可見光燈照射測其可見光光催化性能。紫外燈用的是高壓汞燈

回答(4).在光子激發下，電子被激發出來，形成一個電子和一個孔穴，孔穴可以捕獲電子，而電子可以給予客體， 從而具有氧化還原作用。 影響因素首先是催化劑的屬性，另外是光強度，光波頻率以及反應溫度。

Introduction The development of nanotechnology for the synthesis of nanomaterials is providing unprecedented opportunities to deal with emerging environmental problems associated with water contamination along with worldwide energy-related concerns [1]. Currently, advanced oxidation technologies (AOTs) and nanotechnologies (AONs) have been extensively investigated for the destruction of toxic and recalcitrant organic compounds and inactivation of microorganisms in water and air [2–12]. Titanium dioxide (TiO2), a well-known semiconductor with photocatalytic properties, is a widely used AON for water and air remediation [6– 10]. It has proven to be highly effective in the nonselective degradation of organic contaminants due to high decomposition and mineralization rates. However, conventional TiO2 requires ultraviolet (UV) radiation (l < 400 nm) to overcome its wide band gap energy (3.2 eV for anatase phase) for photocatalytic activation [4,11]. This is a technological limitation when aiming at implementation of large scale sustainable technologies with renewable energy sources such as solar light, since UV radiation accounts only for 5?f the total solar spectrum compared to the visible region (45?[12,13]. Several attempts have been directed towards the development of modi......
