The formation of stable nanoparticle-polymeric reagent obtained by electrostatic complexation is studied in this paper. The nanoparticles placed under scrutiny were nano tetrachlorosilane (SiCl4) reacted with highly branch polyethyleneimine moieties. The complex formation was monitored using different formulation pathways, including direct mixing, sonication, dilution, and quenching. In the first process, the hybrids were obtained by mixing stock solutions of polymer and nanoparticle. 

Therefore, the introduction of new and efficient methods is still in demand. The use of heterogeneous catalysts provides a perfect solution to overcome the above limitations.
