高压汞灯可以用作二氧化钛光催化光源吗

问题描述：不全是，汞灯开的时候你能看见，说明里面必然有可见光，一切高于绝对0度的物体都会辐射红外线的。一般来说300w和波长没有必然联系，因为300w只是一个辐射功率+系统损耗功率，即使是可见光辐射，也可以达到300w

回答(1).₅₀₁₀ ₁₃₃₃

回答(2).哥们 估计不行 二氧化钛 能够吸附 汞（原因如下） 你用了汞灯 必然会有汞被吸附 催化活性应该降低 华盛顿大学的化学工程教授帕瑞蒂姆·拜尔斯瓦 (Pra timBiswas)发明了一种除汞新方法 (美国专利号为6 2 4 82 17) ,将二氧化钛作为吸附剂引入烟道气中 ,可吸收98?汞 ,然后用常规的静电沉降器即可将汞除去。拜尔斯瓦曾试验了几种含硅、钙和钛的吸附剂用于烟道气中除汞。用模拟烟道气 (有或没有SO2 存在的情况下 )试验这些吸附剂 ,发现硅基吸附剂无论在SO2 是否存在的情况下都不捕获汞 ;氧化钙能吸附烟道气中 33?汞 ,但在有SO2 存在时吸附率大大降低 ;二氧化钛的吸附效果最好 ,它对汞的捕获率高达 88? 99?捕获率与…

回答(3).先用紫外灯测试一下其在紫外光下的光催化性能，效果好的话再用可见光灯照射测其可见光光催化性能。紫外灯用的是高压汞灯

回答(4).在光子激发下，电子被激发出来，形成一个电子和一个孔穴，孔穴可以捕获电子，而电子可以给予客体， 从而具有氧化还原作用。 影响因素首先是催化剂的属性，另外是光强度，光波频率以及反应温度。

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......
