Magnetic and optical properties of perovskite-graphene nanocomposites LaFeO₃-rGO: Experimental and DFT calculations
We present an experimental and theoretical study of the perovskite-graphene nanocomposites LaFeO3 – rGO, where we demonstrate a easy way to prepare this compound using citrate auto-compulsion method, starting from corresponding metal nitrate and graphene oxide solution. The Hummer’s method was used...
