Background:
The properties of the material are altered when material size shifted towards
nano-regime. This feature could be used for wastewater treatment process using model pollutant such as
dyes. Recently, nanoparticles are synthesized by a green chemical route using different capping agents.
This is the reason we adopt starch as green capping agent along with sol-gel method.
Objective:
To synthesize cobalt oxide nanoparticles by green chemical route and utilized it in degradation
of dyes.
Methods:
Synthesis of cobalt oxide nanoparticles by sol-gel method using starch as a capping agent.
The characteristics of surface modifications were investigated by UV-VIS, TEM, SEM, XRD and FTIR
techniques.
Results:
Cobalt oxide nanoparticles synthesized and inhibited photocatalytic activity.
Conclusion:
Deactivation of photocatalytic activity due to complex nature of starch. This property can
be used elsewhere as in light shielding applications to coat and protect surfaces in order to keep them
cool and safe from damage as in the painting of vehicles, roofs, buildings, water tanks, etc.
