under ambient aerobic condition[2]. One method for controlling the oxidation is to coat the particles, which means to create a core-shell structure. The shell could protect the nanoparticles from... of tetraethyl orthosilicate (TEOS). 2) The analysis of XRD, TEM, SAED, TG-DSC and VSM indicates that the product has a core-shell structure which is combined through the bonding of Si-O-Fe. 3) Due......
the morphology, crystal structure, particle size, specific area and pore structure. The results indicate that the carbon encapsulated copper nanoparticles have typical core shell structure, the core is metal face centered cubic structure copper, and the outer shell is graphite carbon layer. The particles morphology mainly exhibit spherical or ellipsoidal shapes with relatively uniform particle size......
