Cu is a transition metal, which has a special electronic structure and electronic properties different from those of other group metals.
It can show a good catalytic effect on different chemical reactions, and is widely used in the field of catalysts. When the scale of CuO particles is as small as nanometer, due to the special characteristics of multi-surface free electrons and high surface energy of nanomaterials, it can show higher catalytic activity and more exotic catalytic phenomena than conventional scale nanometer CuO.
As we all know, H2S is a colorless, odorous, odorous, highly toxic toxic gas with an odor threshold of 7.5 × 10-10. And when its volume fraction reaches 1 × 10-4, it can cause poisoning, causing headaches, dizziness and other symptoms. Inhalation of a large amount of H2S will cause coma and even death due to poisoning. Therefore, it is necessary to deal with H2S gas in the air. of. Among various desulfurization methods, dry desulfurization is widely used. Now, the dry desulfurization agents that have been developed mainly include activated carbon, zinc oxide, iron oxide, and various composite desulfurization agents.
It is verified by experiments that CuO nano is an excellent desulfurization product. Deyang guests found in the H2S desulfurization application test that nano CuO can exhibit excellent activity at room temperature, and the removal accuracy of H2S can reach less than 0.05 mg · m-3. After optimization, the penetration capacity of nano-CuO reaches 25.3% at 3000h-1 space velocity, which is higher than that of other desulfurization products of the same type.
