Abstract
The present invention relates to methods and devices for providing microbial control and/or disinfection/remediation of an environment. The methods generally comprise: generating a Purified Hydrogen Peroxide Gas (PHPG) that is substantially free of, e.g., hydration, ozone, plasma species, and/or organic species; and directing the gas comprising primarily PHPG into the environment such that the PHPG acts to provide microbial control and/or disinfection/remediation in the environment, preferably both on surfaces and in the air.
Claims7
A method for microbial control and/or disinfection/remediation of an environment, the method comprising:
- (a) generating a gas comprising non-hydrated hydrogen peroxide gas from humid ambient air by exposing a metal, or metal oxide, catalyst to ultraviolet light in the presence of said humid ambient air for a residence time on said catalyst of less than a second, so as to form said non-hydrated hydrogen peroxide gas, wherein the non-hydrated hydrogen peroxide gas comprises 0.015 ppm of ozone or less;
- (b) directing the non-hydrated hydrogen peroxide gas into the environment;
- and (c) allowing the non-hydrated hydrogen peroxide gas to provide microbial control and/or disinfection/remediation in the environment, both on surfaces and in the air.
