Chuan and Yang’s H2O2 work published in Science!


Hydrogen peroxide (H2O2) amalgamation for the most part requires significant postreaction cleansing. Here, we report a direct electrosynthesis system that conveys separate hydrogen (H2) and oxygen (O2) streams to an anode and cathode isolated by a permeable strong electrolyte, wherein the electrochemically created H+ and HO2-recombine to frame unadulterated watery H2O2solutions. By improving a functionalized carbon dark impetus for two-electron oxygen decrease, we accomplished >90% selectivity for unadulterated H2O2 at current densities up to 200 milliamperes for every square centimeter, which addresses a H2O2 efficiency of 3.4 millimoles per square centimeter each hour (3660 moles for each kilogram of impetus each hour). Many convergences of unadulterated H2O2 arrangements up to 20 weight % could be gotten by tuning the water stream rate through the strong electrolyte, and the impetus held movement and selectivity for 100 hours.—Getting-Your-New-Cat-House-09-12

This is certainly going to be industrialized!
Nonetheless, after cautiously perusing your artical and supporting materials, I actually have a few inquiries in the oxygen decrease process:

  1. What is the genuine obstruction of the opening electrolyzer, or what are protections of each piece of the electrolyzer, particularly prous SE?
  2. What are the dispersion possibilities between Nafion/Permeable SE/AMI 7001? In which jobs these possibilities play in your electrolyzer?
  3. What is the main explanation you think about the huge current thickness your electrolyzer could reach?
    Might you at any point kindly response inquiries above? I’m very intersted in H2O2 electrochemical blend.
