dc.description.abstractNanogold has been around for centuries and have been used widely in the building industry as glass coatings to reduce transmission, paints and combining with other materials to improve air quality of the environment. Other than the building industry, nanogold has been used in other industries as well. Therefore, is demand for nanogold particles all around and a need to synthesize such particles. Currently, there has been many reports on the synthesis of gold nanoparticles by other research groups. However, these synthesis methods can be slow, expensive and tedious. The reducing agents are toxic and harmful to the environment. Furthermore, the gold morphology is not homogenous in shape and size. Therefore, for the first time, this paper has developed a fast, facile, green and low-cost technique to produce homogeneous hexagonal gold nanoparticles. The novel use of hydrolysed silanes as reducing agent has never been reported. Using the microwave irradiation method is also one of the fastest in the world. Different microwave timing was tested and with longer heating time, particles formed are larger. Varying the concentration of silanes can alter the speed of formation. Also, cooling time dramatically affected the formation of nanogold. The products of the experiments also went through several tests to learn more about shape, bonding and crystalline structure. In the conclusion, enhancements to the current study were discussed.
