Abstract
Reduced graphene oxide (RGO) and silver nanoparticles (AgNPs) have been used to prepare (Bi-2223) composites. The structural and morphological properties of the synthesized initial components and the composites are characterized using X-ray diffraction and Transmission electron microscopy. Two high-temperature superconducting orthorhombic phases of Bi-2223 and 2212 are synthesized at a temperature of 830°C for 16 hours in air. TEM images of the composite confirm the presence of silver nanoparticles (Ag-cubic) with an approximate size of about 10 nm and the specific structure of reduced graphene oxide sheets. Significant exfoliation of the graphene oxide and successful reduction leading to the observation of smooth and singular RGO layers.
