“…Iron oxide nanoparticles with uniform shape and particle size ranging from 7−13 nm have been synthesized from green tea leaves (Singh et al, 2017). To extract bioactive components -mostly polyphenols, from plant material, powdered tea leaves was mixed with aqueous methanol solution, refluxed and decaffeinated first with methylene chloride, then ethyl acetate via a liquid-liquid extraction process.…”

“…Alone, NaBH 4 did not degrade nitrobenzene, but with the introduction of the nanocatalyst, 90 % degradation was achieved within 90 min. Removal of methylene blue (an organic dye pollutant) from solution using iron oxide nanoparticles synthesized from green tea polyphenols has achieved 95 % removal efficiency within 16 min (Singh et al, 2017).

The ever-increasing importance of green-based iron nanoparticles within the last decade and their environmental applications is a compelling reason to probe novel routes for their synthesis. Therefore, the principles of green chemistry, waste prevention, energy efficiency, safer solvents, and the benign precursor materials have become fundamental considerations in the synthesis process of these materials, birthing extensive study in this field. In this light, a comprehensive discussion of the successes of greener techniques and other biological nanotechnologies including the use of microorganisms (fungi, bacteria, actinomycetes, and viruses), algae, plant and their extracts for the synthesis of iron (Fe) nanoparticles (NPs) is presented. Although promising findings have been reported, substantial research gaps and the opportunity to capitalize on the emergence and rise of these eco-friendly sources have been identified. The application of synthesized nanoparticles for environmental remediation and their toxicological implications are also discussed.

“…On the other hand, increase in temperature resulted in increased nanoparticle reactivity and enhanced degradation of the dye; however, this could also stimulate aggregation due to reduced capping ability of bioactive molecules at high temperature. Maximum degradation of malachite green dye (over 90%) was achieved with 1:1 ratio of volumes of tea extract and metal ion solution at pH 6.0 and 45°C temperature [61,62].…”

“…Degradation of organic dyes is probably one of the most studied and widely reported applications of nanoparticles [62,97,98]. Degradation of Congo red by iron oxide nanoparticles synthesized using pomegranate leaf extract [65], degradation of methyl orange by iron oxide nanoparticles synthesized using Pisum sativum peels [66], degradation of methylene blue by silver nanoparticles synthesized using Tabernaemontana heyneana leaf extract [60], and degradation of malachite green using nickel supported nanoparticles synthesized from Moringa oleifera leaf extract [99] are few examples of such studies.…”

At present, natural resources are very limited and inadequate for increasing global population along with uncontrollable environmental pollution. The development of advanced eco-friendly technology and pollution free environment is very necessary for the current situation. Nanotechnology is playing a vital role in the development of "cleaner" environment and "greener" technologies for sustainable livelihood and environment. Nanotechnology is involved in many sectors like pharmaceuticals, agriculture, food, energy, environment, cosmetics, electronics, chemicals, and so on. There are many consumer products containing nanomaterials available in the market for ready use by human beings. Hence, human exposure to nanomaterials is possible to occur during processing at occupational level and personal usage at consumer level. At present, nanotechnology is a promising tool as it has high performance and is cost-effective in

“…They tested the synthesized hybrid for the adsorption of Rhodamine B dye and found the maximum adsorption capacity of 216 mg/g. Singh et al [64] had synthesized the superparamagnetic nanoparticles coated with green tea polyphenol by wet chemical method. They found that the particles have a very high adsorption capacity of (7.25 mg/g) for removal of methylene blue (MB) dye in wastewater treatment.…”

Water is a primary element for all living things, and we need water for each and every dayto-day activity related to agricultural, industrial, and domestic cares and, thus, its quality influences all aspects of human life including energy, food, health, and economy. Safe drinking water is our primary need to protect our life and thus developing efficient and affordable techniques for water treatment to access potable water to the humanity. Water pollution is one of the severe environmental and health problems worldwide. Pollutants in water can be of organic, inorganic, heavy metals, microbial, and radioactive species, which may be in different forms viz. suspended, dissolved, or dispersed materials. The water quality is mainly affected by industrial discharges, agricultural activities, mismanagement of hazardous materials, etc. Nowadays, nanotechnology offers the possibility of an efficient removal of water pollutants including metals, organic dyes, bacteria, parasites, etc. Magnetic nanomaterials like iron oxide (Fe 3 O 4) are very promising materials used in water decontamination particularly for heavy metals and dyestuffs because of their ease of separation through external magnet, high surface area, unique morphology as well as their high stability. These materials can be used as adsorbent, photocatalyst, and coagulating agents for water remediation based on their composite materials or surface functionalities.
