Researchers at RMIT University in Melbourne have developed a unique paint containing a compound that acts like silica gel, absorbing moisture from the air and turning it into hydrogen fuel for clean energy. The compound acts as a semiconductor and catalyzes the splitting of water atoms into hydrogen and oxygen, and mixing itwith titanium oxide particles leads to a sunlight-absorbing paint.
“Titanium oxide is the white pigment that is already commonly used in wall paint, meaning that the simple addition of the new material can convert a brick wall into energy harvesting and fuel production real estate.”
The team estimates that it will take at least five years to commercialize the paint, but then it should be inexpensive to produce.
