摘要: The preparation of graphene/iron oxyhydroxide hybrid electrode material with very homogeneous distribution and close contact graphene amorphous iron nanoparticles has been achieved by using high-intensity ultrasonication. Due to the negative charge surface, ions are attracted toward surface dispersed graphene, according zeta potential measurements. anchoring FeO(OH) particles layers revealed mainly TEM, XPS EPR. TEM observations show that size oxide is about 4 nm. ultrasonication treatment key parameter achieve small particle in these materials. electrochemical behavior composite graphene/amorphous prepared outstanding terms gravimetric capacity cycling stability, particularly when metallic foam used as both substrate current collector. XRD-amorphous character contribute improved performance.
