nature an experiment i don't know yet why is like so far like it sounds so simple they had no idea

but now the data's i find this not only refreshing but but at some level astounding nature

welcome back to the Nature.

Welcome back to the nature podcast.

This week, splitting water with light and a measure of matter in the universe.

I'm Charmoney Bandell.

Thank you. And I'm Nick Al.

First up, for decades, hydrogen has been touted as a sustainable fuel for the future.

When hydrogen burns, it releases a lot of energy, but only emits pure water. No greenhouse gas or pollutants to worry about. The problem is that most methods of producing hydrogen fuels,

either rely on fossil fuels, or are too energy and cost intensive to be feasible on a large scale.

But what if you could produce it

cleanly using nothing but water and sunlight? Hydrogen from pure water and solar energy,

it can be really clean and renewable hydrogen. This is Kazanari-domen. Water is made up of one

oxygen atom and two hydrogen atoms and Kazanari specialdomen. Water is made up of one oxygen atom and two hydrogen atoms, and

Kazanari specialises in developing materials which can use light to split water, releasing

the hydrogen. These materials are called photocatalysts, and they've been around for decades,

but so far they have been too inefficient to be useful at scale.

This week in nature, though, Kassanari has developed a photo catalyst with almost 100% quantum efficiency,

meaning nearly every absorbed photon is used to make hydrogen.

I myself was actually surprised.

Two years ago, we achieved almost 70% quantum efficiency.
