SUMMARY

The discussion focuses on the creation of free superoxide in air, emphasizing that it is distinct from ozone, which is co-produced in processes generating superoxide. A high-voltage (HV) electrode operating in air primarily generates ozone and superoxide. The conversation explores the potential of using a helium jet directed at the HV cathode to inhibit ozone formation, allowing free electrons to interact with oxygen to produce superoxide. It is established that oxygen must be in the corona of the HV cathode for ozone formation, while superoxide can form from direct contact with free electrons.

PREREQUISITES
  • Understanding of high-voltage (HV) electrode operation
  • Knowledge of superoxide and ozone chemistry
  • Familiarity with the concept of negative air ions
  • Basic principles of electron transfer in chemical reactions
NEXT STEPS
  • Research methods for generating free superoxide without ozone
  • Explore the effects of helium jets on high-voltage processes
  • Study the chemistry of superoxide and its applications
  • Investigate the role of electric fields in ion formation
USEFUL FOR

Researchers in atmospheric chemistry, electrical engineers working with high-voltage systems, and anyone interested in the generation and applications of superoxide and negative air ions.

this question relates to creating free superoxide so it is not a superoxide of anything. another more un-accurate but common name for it is a negative air ion.
in air, ozone is always going to be co-created in any process that creates superoxide.
a HV electrode (-) in air produces mostly ozone and superoxide. but how to make the superoxide without the ozone?
would a helium jet directed onto the HV cathode prevent the ozone being formed and allow the electrons to temporally stay in the helium until they contact oxygen and get transferred to the oxygen (as oxygen is electronegative) thereby creating free superoxide?
[[info: oxygen needs to be in the corona of the HV cathode for ozone to be formed due to the UV and strong electric fields. whereas superoxide needs only for oxygen to come in contact with free electrons.]]
