▎ 摘 要
SnO2@reduced graphene oxide nanocomposite (SGNC) was fabricated via a colloid electrostatic self-assembly process between the graphene oxide (GO) nanosheets and Sn(OH)(4) colloid nanoparticles (NPs), following a heat-treatment at 550 degrees C for 2 h under N-2. Transmission electron microscopy (TEM) and high resolution transmission electron microscopy (HRTEM) showed the tiny multi-crystalline SnO2 NPs (
