A team led by Professor Lu Yun of Chiba University in Japan recently announced that the new titanium dioxide photocatalytic film pellets developed by the team in cooperation with Tokyo-based SNS soft can effectively inactivate the new coronavirus and help develop new environmental purification products
for disinfection and sterilization.
for disinfection and sterilization.
A press release provided by the team said that studies have proved that titanium dioxide absorbs light energy under light irradiation to decompose organic pollutants and kill bacteria and viruses
.
The paper has recently been published in
the British journal Scientific Reports.

the British journal Scientific Reports.
The team has been engaged in the research and development of titanium dioxide photocatalytic materials for nearly 20 years, exploring their high performance and air and water purification applications
.
Titanium dioxide photocatalytic thin film pellets are prepared
by mechanical film forming method, a new film-forming technology developed by the team.
The idea comes from the reverse thinking of mixing and crushing metal powders using ball mills in powder metallurgy, and using friction, impact and bonding in ball mills to realize simple and inexpensive metal film forming technology
.
Titanium dioxide photocatalytic film pellets can be prepared by mechanical film-forming method on the surface of alumina pellets, and titanium dioxide photocatalytic film pellets
can be prepared by subsequent heat treatment, salt bath treatment, acid bath treatment, etc.

The test results commissioned by third-party research institutions show that this pellet has a very high inactivation rate of new coronavirus and influenza virus and decomposition of formaldehyde and acetaldehyde, of which the inactivation rate of new coronavirus is 99.
99% and the inactivation rate of influenza virus is 99.

The researchers said that the function of titanium dioxide photocatalytic materials to sterilize and sterilize under light stems from the active oxygen species
produced during light.
Active oxygen species have strong redox properties, can decompose organic matter that pollutes the environment, and have a strong sterilization and sterilization function
