Abstract

Plant derived carbon was utilized as a new financial and environmental friendly colorant in the synthesis of zircon encapsulated carbon pigment (C@ZrSiO4) via non-hydrolytic sol-gel method. After calcining, nature plants, i.e. sisal and bamboo leaves, were carbonized and occluded in ZrSiO4 matrix. The FT-IR and XRD results demonstrated that the plants were not affect the non-hydrolytic sol-gel polycondensation reaction, resulting in the pure ZrSiO4 formation. Both inclusion pigments presented deep black hue, i.e. L??=?34.93 and 33.02 for sisal and bamboo leaves, respectively, which was contributed to the homogeneous pore-size distribution and high carbon yield of the plants. These pigments have many distinguished advantages including low cost, high chromatic performance and excellent thermal stability, making them promising candidates for ceramic decoration.

Abstract

A novel green synthesis of cobalt oxide (Co3O4) nanoparticles using latex of Calotropis procera via simple precipitation method at room temperature was investigated. An extensive characterization of the product was carried out using X-ray diffractometry (XRD), Differential scanning calorimetry (DSC), Transmission electron microscopy (TEM), Energy dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FTIR) and UV–Visible spectroscopy. The results of the characterization confirmed that the synthesized nanomaterial is highly dispersed. TEM analysis revealed that the nano particles are having an average size around 10?nm. The eco-toxic investigation suggested that the particles are non-toxic and safe towards the environment. This green strategy proves to be an effective, fast, simple and cost-effective approach for the synthesis of Co3O4 nanoparticles for various applications.
