Good evening everyone
I am working on green synthesis of selenium nanoparticles from leaf extract. The research article mentions that during selenium nanoparticle synthesis, ascorbic acid should be used as a catalyst. so why there is a need to use a catalyst?., and what is the best drying method for synthesized selenium nanoparticles?
Is a reducing agent or capping agent which makes the material dispersabe in any solution. Ovum drying is ok with mild temperature.
Hi Mohini Tayade,
A catalyst is a substance that can be characterized as homogeneous which is in the same phase as the reactants liquid or gas, and heterogeneous, or enzymatic that are not in the same phase as the reactants. When catalysts are added to a reaction, it increase the reaction rate without getting consumed in the process, in addition to accelerating a reaction by reducing the activation energy or changing the reaction mechanism, so, it prevents agglomeration when synthesizing the nanomaterial.
