Development of the Composite Photocatalytic Filter
2012 (Age 14)
Driven by her observations in India, Deepika began experimenting with photocatalysis, a process that uses sunlight to purify water. After much research and experimentation, she developed a novel composite photocatalytic filter using sand, titanium dioxide, and silver nanoparticles. This invention proved to be significantly more effective and affordable than existing water purification methods.
