Fig. 6 Synthesis of bimetallic nanoparticles
2.2.2 Bimetallic Nanoparticles (BMNPs)
Syntheses of nanoparticles by a combination of two metal nanoparticles are termed
as “bimetallic nanoparticles” (BMNPs) (Mazhar et al. 2017). In this type of nanoparticle, two metal nanoparticles have separate function to carry out overall reaction. Bimetallic nanoparticles have specific catalytic and selective activity than
monometallic nanoparticles. Syntheses of bimetallic nanoparticles from different
microorganisms were shown in Fig. 6.
There are several methods for the synthesis of bimetallic nanoparticles. The most
commonly used methods are synchronous complexing method, sequential complex
method, and partial substitution method. In synchronous method, two different metal
ions are mixed with polymers to make bimetallic nanoparticles. The most commonly
used bimetallic nanoparticles are shown in Fig. 7.
2.3 Factors Influencing the Synthesis of Nanoparticles
Various factors, such as temperature, pressure, pH, time, particle size, shape,
and the concentration of the extracts, affect the synthesis and characterization of
