Abstract

Copper nanoparticle was prepared by aqueous solution reduction method. Cu2+ was reduced to a copper particle by using different types of reductants named ascorbic acid (C6H8O6), phosphinic acid (H3PO2), titanium sulfate (Ti2(SO4)3) and sodium borohydride (NaBH4). The effect of reaction driving force on the average size of copper particles was investigated. An inversely proportional relationship between the reaction driving force and the average size of copper particles was found, wherein the average size of copper particles decreases as the reaction driving force increases.
