Phytogenic Synthesis of Metal/Metal Oxide Nanoparticles for Degradation of Dyes

Abstract

Now-a-days nanotechnology is one of the booming fields for the researchers. With the increase in industrialization mainly textile, paper, medicine, plastic industry, there is an increase in concentration of organic dyes as pollutant. Release of harmful dyes in water bodies has become a serious issue, as most of the dyes are carcinogenic and mutagenic in nature and causes various diseases. Therefore, there is a requirement to find out new approaches for efficient treatment of effluent containing dyes. Nanoparticles are one of the potential solutions to this problem. They can be synthesized from different methods, however synthesis of nanoparticles from different plant parts (leaf, root or stem extract) is economical as well as ecofriendly. Phytogenic nanoparticles have various environmental applications and one of them is remediation of dyes. The aim of this review is to provide an overview of last five years studies about catalytic and photocatalytic degradation of various harmful dyes by plant synthesized nanoparticles, mechanism of degradation and advantages and disadvantages of phytogenic synthesis.

Synthesis and Applications of Green Synthesized TiO2 Nanoparticles for Photocatalytic Dye Degradation and Antibacterial Activity

“…Primary ingredients include chlorophyll, proteins, and simple carbohydrates, whereas secondary chemicals include terpenoids, alkaloids, and phenolic chemicals. Many health concerns, such as cancer, heart disease, diabetes, and high blood pressure, are being pushed for the prevention and treatment of phytochemicals [9][10][11][12]. Morus plant has shown strong antifungal activities.…”

Polyol-mediated zinc oxide nanoparticles using the refluxing method as an efficient photocatalytic and antimicrobial agent

“…Recently, researchers have developed nanofibrous scaffolds to guide tissue regeneration and stimulate cell growth ( Mirzaei and Darroudi, 2017 ). The unique properties of nanomaterials have made them attractive candidates for a wide range of applications in various fields ( Roy et al, 2022b ). With ongoing research and development, the potential for nanotechnology to revolutionize multiple industries and address significant societal challenges is promising.…”

Nanomaterials: A Potential Hope for Life Sciences from Bench to Bedside

“…We ought to recognize nanoscience, and nanotechnology. Nanoscience is the investigation of designs and particles on the scale of nanometres going somewhere in the range of 1 to 100 nm, and the innovation that uses it in reasonable applications example, gadget and so forth is called nanotechnology [3]. Nanotechnology (NT) is a multidisciplinary field that encompasses nanoscience, nanochemistry, nanophysics, nanomaterials, nanoelectronics, nanometrology, nanobionics, and other fields.…”
