Heterogeneous Coreshell Photocatalyst
Description
This invention removes contaminants and microorganisms from polluted water using affordable nanotechnology to resolve the low decontamination effectiveness of current options
Problem
Current photocatalysts are prepared by time-consuming, tedious and not-cost effective processes. They also may show high decontamination effectiveness but slow decontamination rate.Solution
This invention addresses a method of developing transition metal oxide (or sulfide) based nanostructured photocatalysts that enhances both decontamination effectiveness and rate. Additionally, the photocatalysts are remarkably cost-effective and reusable.
Competitive Advantages
- Both TiO2 and sugar are cheap source materials
- The shell coating process on TiO2 core is facile and low-cost
- No high temperature annealing under inert atmosphere is needed to convert the carbon source into carbon-based adsorbent.
- The decontamination process can be conducted at room temperature and atmospheric pressure
- The resulting nanostructured heterogeneous core@shell photocatalysts show surprisingly high decontamination efficiency (~100%) and rapid decontamination rate (< 30 min).
