nanocomposites are prepared using different A-metal salts (Sr (NO3) 2, Ba (NO3) 2 and Ca
(NO3) 2). The procedure is based on a redox reaction between the metal precursors and
graphene oxide (GO) using two different routes of reaction initiation: through thermal heating
or by microwave-assisted heating. The resulting nanocomposites do not require further
calcination, making this method less energy-demanding. In addition, no additional chemical …
