| Research Abstract |
Common metal nanoparticles of Cu, Ni and so on were prepared with liquid phase reduction method. The reaction parameters were optimized through a series of contrast experiments. The reaction mechanism was also explored. Four types of reductants, such as C6H8O6, H3PO2, Ti2(SO4)3and NaBH4indicate that there is an inversely linear relationship between the reaction driving force (ΔE) and the mean size of Cu particles. Cu particles of 30 nm in size can be obtained from Cu(OH)2precursors using NaBH4as strongest reductant in at 313 K, pH 12 for 30 min in copper sulfate solution. The morphology of deposited metal particles was changed to particle, wire, plate with the amount of additive cetyltrimethylammonium bromide (CTAB) as template in the solution of ascorbic acid as weak reductant and copper sulfate. The reaction process was discussed electrochemically using mixed potential diagram.
