| description | Alumimum/cobalt nanocomposite was fabricated by displacement method, wherein NH4F and gelatin played significant roles in deposition of Co nanoparticles. The as-prepared Al/Co was etched by strong acid and alkali respectively. In acid solution, micron structure of the residue presents hollow Co shells, whereas the product separated from alkali shows fragments made up with metal Co. Analyzing the distinguishable results, possible mechanisms of etching in acid and alkali were inferred. Thermal analysis indicated that the reactivity of Al/Conano was great higher than Al/Cosubmicron and raw Al. The ΔHr and Qmax of Al/Conano-PbO increased by 493.2 J·g-1 and by 13.65W·g-1 over Al/Cosubmicron-PbO, as well as roughly by 520.6 J·g-1 and by 16 W·g-1 over raw Al-PbO system. |
