Application of cobalt-tin hydroxide in catalytic degradation of nicotine pollutants and preparation method of cobalt-tin hydroxide

The invention discloses application of cobalt tin hydroxide CoSn (OH) 6 in catalytic degradation of nicotine pollutants and a preparation method of the cobalt tin hydroxide CoSn (OH) 6. The cobalt tin hydroxide serves as a catalyst, is a double-metal hydroxide of a cubic structure and can catalyze and activate peroxymonosulfate to oxidize and degrade nicotine pesticides under the normal-temperature condition so as to remove pollutants in water; particularly, the bacillus subtilis has a good degradation effect on acetamiprid (ACE). 本发明公开了一种钴锡氢氧化物CoSn(OH)6催化降解烟碱类污染物的用途及制备方法，该钴锡氢氧化物作为催化剂为具有立方体结构的双金属氢氧化物，能催化活化过氧单硫酸盐在常温条件下氧化降解烟碱类农药，以除去水中的污染物，特别是针对啶虫脒(ACE)具有良好的降解效果。
