Problem Statement
- There are uses of photocatalytic materials for wastewater treatment. These materials are semiconductors & others.
- A few photocatalysts like TiO2 based materials are used commercially, however retrieving & recycling of said photocatalysts are challenged in terms of scale, when said photocatalyst are used in the process of slurry-based water treatment.
- Further other photocatalyst materials discussed present problems with assaying of its toxicity & other issues.
- Hence, there is a requirement of an improvised process to address the above issues efficiently.
Technology
- Patent literature talks about a process of synthesis of magnetic photocatalyst Aluminium ferrite (AlFeO3) as shown in smart charts.
- The AlFeO3 having optical bandgap of 2.0eV, enables sunlight driven photoactivity.
- Further, the subject matter describes the process for treatment of water using said photocatalyst AlFeO3 as shown in smart charts.
- The process of treatment of water using photocatalyst AlFeO3 achieves better performance shown in figures.
