A New Way to Fight Indoor Ozone with a Special Catalyst

You know how ground-level ozone (O3) can be bad for both the environment and our health? It's even worse when it gets inside our homes. One big problem with removing this ozone is that moisture can mess up the catalysts that are supposed to do the job. Scientists have found a clever way to make a catalyst that doesn't mind moisture. They started with a special material called a bimetallic-organic framework, which is like a tiny building made of metal and organic parts. They turned this building into a carbon-supported catalyst with cerium oxide (CeO2), cobalt (Co), and cobalt oxide (Co3O4).This new catalyst can remove ozone really well, even when it's humid. It's like having a superhero that can fight ozone in any weather! The scientists checked how well it worked under different humidity levels and found that it could remove almost all the ozone, even when it was very humid. They also found that the catalyst had special spots called oxygen vacancies that helped it grab and activate the ozone. Plus, it was really stable and could be reused many times. This new way of making catalysts could help us get rid of indoor ozone for good.
