New silver catalyst for air-cleaning devices

According to news in, sourced from Tomsk State University (TSU), Russia, chemists at the university are creating a new silver catalyst to purify the air, which is capable of decomposing toxic carbon monoxide, formaldehyde and other harmful volatile substances into harmless components. This nanostructure catalyst, the news story said, may be effective even at room temperature, and could be used as a filter for ventilation. Gregory Mamontov, senior researcher at the Laboratory of Catalytic Research, said: “It is assumed that the catalyst obtained in the form of powder or granules can be put into air-cleaning devices in homes, offices or production halls.”
