Credit: IPC PAS, Grzegorz Krzyzewski The air around us is getting more and more polluted. No wonder many scientists strive to find a way to purify it. Thanks to the work of an international team led by prof. Juan Carlos Colmenares from the Institute of Physical Chemistry, Polish Academy of Sciences, we are a big step closer to achieving this goal. The team found a way to make an efficient reactive adsorbent able to purify air from various toxic compounds, cheaply, and effectively.

“Most important is the material we made at the laboratory,” says prof. Colmenares. “It not only adsorbs toxic vapors from the air but also, thanks to its photocatalytic properties, can break them into less toxic elements.” Material made by the team consists of two quite cheap and easy to acquire compounds: titanium dioxide and graphite oxide. “We intended to make it widely available,” explains the professor, and “environmentally friendly.” The innovation here was to use ultrasound to make the two counterparts—one organic and one inorganic—to co-operate. The organic counterpart catches the toxic particles, and […]
