Fluorine tin modified boron-doped diamond film electrode, preparation method and application thereof

The invention discloses a fluorine tin modified boron-doped diamond film electrode, a preparation method and application thereof. The method comprises the following steps: firstly, preparing a BDD electrode formed by closely accumulating crystal particles, then uniformly mixing and stirring styrene, phenol, polyoxyethylene ether, SnCl2 and NaF, dissolving the mixture with water and ethanol, and adding methenamine, so as to form precursor turbid solution, coating the precursor turbid solution on the surface of the BDD electrode in a spin coating manner, preparing F and SnO2 coating, and finallyperforming calcining at certain temperature, so as to obtain the BDD/SnO2-F electrode. The BDD film electrode is uniform and compact in surface, has high oxygen evolution potential and good corrosionresistance, and is high in electrooxidation capacity; being an anode, the BDD film electrode is good in degradation effect when treating difficulty decomposed organic waste water. 本发明公开了种氟锡修饰的掺硼金刚石薄膜电极及其制备方法和应用。所述制备方法包括以下步骤：首
