Problems solved by technology

However, there are some obvious shortcomings in the application of electrochemical oxidation technology at present: for example, the current efficiency and energy efficiency are low, the energy consumption is high, the catalyst is difficult to load, and the particle size and shape are difficult to control. After the reaction, the product cannot leave the electrode surface in time, which not only hinders the progress of the new reaction, but also leads to deep oxidation of the product, which greatly limits the application of electrocatalytic oxidation reaction and technology

[0004] However, there are many problems and deficiencies in the electrocatalytic membrane electrodes prepared based on traditional sol-gel or dip-coating methods: for example, it is difficult to control the composition, shape, size and other properties of nanoparticles, and the force between them and the base membrane Weaker, the stability of the membrane electrode is poor, which leads to low current efficiency and energy efficiency of the electrocatalytic membrane electrode and membrane reactor, poor catalytic performance, and difficult adjustment of the oxidation reaction, which greatly limits the electrocatalytic membrane electrode and membrane.
