Copper Nanoparticles: Synthetic Strategies, Properties and Multifunctional Application

Abstract

Copper nanoparticles received much attention due to its high electrical conductivity, high melting point, low electrochemical migration behavior and low cost. Top down (physical methods) and bottom up (chemical and biological) approaches adopted for the synthesis of copper nanoparticles are reported. The property of copper nanoparticles mainly depends on the synthesis route and their process parameters. The influence of process parameters on the morphology, growth and yield of the nanoparticles by adopting various synthesis methods are discussed in detail. From the earlier reports, it is proved that electrochemical and chemical reduction method have received much higher attention due to their simple operation, low cost, faster reaction rate, high yield, environment friendly and low energy consumption. The characterization techniques, advantages and limitations of each synthesis methods are also discussed. The extensive applications of copper nanoparticles in various fields are also highlighted.

Fabrication and Characterization of Copper Nanoparticles by Green Synthesis Approach Using Plectranthus Amboinicus Leaves Extract

“…By the reduction process using CuSO4 as the precursor, the copper nanoparticles are synthesized [9]. For synthesizing copper nanoparticles there are three methods, namely chemical, physical, and biological methods [10].…”

Biogenic copper nanoparticles and their applications: A review

“…The cost of noble metals is very high when compared with copper. Therefore, copper is mostly preferred for fabricating highly conductive Cu patterns on a plastic substrate by inkjet printing because of its low cost and high conductivity [124,147]. The challenge in the use of Cu NPs is rapid oxidation affinity [85].…”

A minireview of copper material applications in bioelectrochemical sensing

“…They are more reactive compared to other metallic NPs. (Tamilvanan et al, 2014;Wu et al, 2014) Among various methods of NPs synthesis, electrochemical one raise much interest due to its simplicity and low costs. NPs are produced in situ in the electrochemical cell through metal ions reduction from the electrolyte onto electrode material by the applied potential.…”
