황산동 수용액으로부터 hydrazine 환원에 의한 Cu 미립자의 합성
Synthesis of Uniform Cu Particles by Hydrazine Reduction from Copper Sulfate Solution
E-mail:
In order to prepare the uniform copper particles from copper sulfate solution by using hydrazine as a reduction agents, the reduction behavior of copper particles from copper sulfate was investigated in detail at room temperature by the observation of reaction products. The effects of OH and on the formation of uniform copper particles were discussed. ()was completely formed at over pH 11 by adding OH in copper sulfate solution. The fine O with the particle size of 50 nm was produced in the initial reduction process of (NH)solution with and then the CuO was converted into copper particles by inserting additional hydrazine. When Cu(NH)SOsolution with was reduced at by hydrazine, the highly dispersed copper particles with the particle size of about 0.8 was obtained.
