Australian scientists have managed to find a way to produce hydrogen from water contained in the air. A special coating is used, which is applied to the window glasses.

In the course of the experiment, molybdenum sulfide nanoparticles were used. This compound actively absorbs water vapor from the air, and then the water molecules split. This produces pure hydrogen, which can be used as an environmentally friendly fuel.

The authors mixed nanoparticles of molybdenum sulfide and titanium oxide, applied to a transparent and flat surface - glass, and irradiated with light. As a result, the process speed has significantly increased. This method will be even more effective when replacing titanium oxide with silicon.

With the help of such films, it is possible to obtain hydrogen almost everywhere - the main thing is that the sun's rays get on the windows, and the air contains water vapor, at least in minimal quantity.

The scope of the new method is very wide - it is not only the production of hydrogen fuel, but also the creation of high-sensitivity humidity sensors and autonomous dehumidification systems that do not need a power source.
