It opens up in solution.It flows to cathode using the electronics that light anode generates, and the hydrogen reduction process for passing through cathode forms H2O2, make it
With Fe2+HO is generated in the solution·, the radical reaction in fortification system.If Noradiba Nordin et al. are in Separation
177 (2017) 135-141 of and Purification Technology publish an article Hybrid system of
photocatalytic fuel cell and Fenton process for electricity generation and
Degradation of Reactive Black 5 are joined using Fenton and photocatalytic fuel cell two independent reactor
With：The electronics generated by photocatalytic fuel cell reactor light anode is transferred to the cathode of Fenton reactors simultaneously by external circuit
Oxygen reduction generates H2O2, the organic matter in photocatalytic fuel cell is degraded in anode surface；In Fenton reactors, Fe sun
Pole generates Fe by peroxidating process of setting2+And electronics, Fe2+The H generated with cathode2O2Fenton processes are formed, generate HO·Degradation
Organic matter, electronics are then transferred to the cathode of photocatalytic fuel cell reactor by external circuit, form closed circuit.Patent
CN106299418 proposes " the photocatalysis wastewater fuel cell, manufacture and preparation method and application of strengthening radical reaction ", in illumination item
Under part, ferrous ion and the free radical and H that are generated in light anode and cathode surface2O2, make in the automatic bias of photocatalytic fuel cell
With it is lower occur Fenton-like circular response, so as to the radical reaction in fortification system.For above system, although
It is good to the degradation efficiency of organic matter in Fenton reactors, but generate wherein H2O2Generate or will rely on electrode surface area and
Oxygen supply, is also extremely limited the promotion of photocatalytic fuel cell performance.
Invention content
Mass transfer can be improved the purpose of the present invention is to provide one kind, cost is reduced, do not need to additionally add energy, produce
The photocatalytic fuel cell and persulfate that raw any harmful substance, organic pollutant degradation and generating capacity are obviously improved activate
