Researchers develop novel method to photosynthesize hydrogen peroxide using water and air
Researchers at the National University of Singapore (NUS) have developed a microporous covalent organic framework with dense donor鈥揳cceptor lattices and engineered linkages for the efficient and clean production of hydrogen peroxide (H2O2) through the photosynthesis process with water and air.
Traditional industrial production of H2O2 via the anthraquinone process using hydrogen and oxygen is highly energy-intensive. This approach employs toxic solvents and expensive noble-metal catalysts and generates substantial waste from side reactions.
In contrast, photocatalytic production of H2O2 from oxygen and water offers an energy-efficient, mild, and clean route. Most importantly, it addresses the common drawbacks of existing photocatalytic systems, such as low activity, heavy use of additional alcohol sacrificial donors, and the necessity for pure oxygen gas input.
A study published in ACS Applied Materials & Interfaces describes a novel method of producing hydrogen peroxide (H2O2) without emitting carbon dioxide (CO2), one of the main greenhouse gases and one of the world's most widely produced chemicals.
Hydrogen peroxide is used to bleach fabric, pulp and paper, and to whiten teeth. It is also used as a thruster fuel for satellite attitude control, and as a disinfectant or sterilizing agent by hospitals. Some 2 million metric tons of the compound are produced annually.
"To understand the impact of our findings, it's important first and foremost to bear in mind the significance of H2O2 in the chemical industry and the way it's currently produced," said Ivo Freitas Teixeira, a professor of chemistry at the Federal University of S茫o Carlos (UFSCar) in S茫o Paulo State, Brazil. He has a Ph.D. in inorganic chemistry from the University of S茫o Paulo (USP) and was a Humboldt Fellow at the Max Planck Institute of Colloids and Interfaces in Potsdam, Germany, between 2019 and 2021.
Some great tips here. A couple of the suggested uses were new to me, but I鈥檓 definitely going to give them a try! They will be a good use of my expiring stock when I go to replace it with fresher bottles, too.
Maybe everyone already knows this and I鈥檓 just an idiot, but the other day I learned you are NOT supposed to clean wounds with hydrogen peroxide because of a bunch of science nonsense that I鈥檓 not going to attempt to reiterate but basically it will end up making it a lot harder for your body to complete the healing process?

Shout-out to Boomer/Gen X parents who wrestled with their kids to apply hydrogen peroxide to their "boo-boos" and had to watch them suffer, only to later discover that it makes it WORSE.
You were doing the best you could with the information you had.
Shout-out to the millennial kids who had to endure a second, worse injury to their "boo-boos" only to discover etc.
I remember 7 y/o me crying when I fell on the bus stairs, not because I skinned my knee, but because I knew what Happened Next.
