After four hours, the CMO powder reduced the level of coronavirus by four orders of magnitude (to less than 1/10,000 of the original level). The antiviral activity of CMO against coronavirus was found to exceed that of both LCMO and MoO

Researchers at Tokyo Institute of Technology working in collaboration with colleagues at the Kanagawa Institute of Industrial Science and Technology and Nara Medical University in Japan have succeeded in preparing a material called cerium molybdate (γ-Ce2Mo3O13 or CMO), which exhibits high antiviral activity against coronavirus.
The ongoing coronavirus pandemic has highlighted the urgency not only of vaccine development and rollout but also of developing innovative materials and technologies with antiviral properties that could play a vital role in helping to contain the spread of the virus.
