Plant-Mediated Biosynthesis and Photocatalysis Activities of Zinc Oxide Nanoparticles: A Prospect towards Dyes Mineralization

Table 1

Comparison between the plant extract and another microorganisms system.

Biological source	Plant	Microorganisms
Preparation time	Short	Longer than plant due to incubation time
Components responsible for reducing metal salts into metal nanoparticles	Phytochemicals	Enzymes/proteins
Production yield	High	Lower than plant
Solvent	Water	Natural source/extract
The cost	Effective	Less effective
Procedure	One-pot synthesis process	More complicated
The location of nanoparticles formation	Intracellular (expensive) and extracellular	Intracellular synthesis and extracellular synthesis.
