Highly dispersed ternary Ag/C/SnO2 hollow spheres have been synthesized for hydrazine electro-oxidation. The sharp XRD peak of Ag shows that nanoparticles good crystallinity. SEM maintained a spherical morphology with the diameter about 300 nm. TEM average 10 nm disperse well on C/SnO2. advantages derived from C/SnO2 support including carbon, SnO2 and structures may facilitate dispersion close ...
