DSA electrode based on phenolic resin assistance and preparation method and application thereof

The invention discloses a DSA electrode based on phenolic resin assistance and a preparation method and application thereof. The DSA electrode based on phenolic resin assistance is composed of a titanium metal matrix, a carbon middle layer and an active metal oxide layer loaded on the carbon middle layer. The loading capacity of the carbon is 1-30% by taking the mass of the titanium metal matrix as 100%; the loading capacity of the active metal oxide is 2-50%; and carbon in the carbon middle layer is obtained by carbonizing thermoplastic or thermosetting resol in a high-temperature inert atmosphere. The prepared DSA electrode based on phenolic resin assistance shows good reaction activity and stability in a phenol degradation experiment, the degradation rate of phenol within one hour can reach 98.7%, and the electrode is not obviously inactivated after 20 times of repeated reaction. The DSA electrode forming process based on phenolic resin assistance can be realized under relatively mild conditions, and compa
