604GO/AuNPsTEMFrom the inserted TEM, it can be seen that the small amount of spherical nanoparticles with the particle size of about 30 nm were uniformly dispersed and embedded on the surface of GO. The graphene sheet is covered with tightly compressed spherical nanoparticles with particle size of about 30 nm, which should be gold nanoparticles.
