“…In this conceit, photo‐degradation of organic pollutants has recently attracted much interest as one of the finest techniques for decontamination of the wastewater. Some inorganic metal oxide semiconductors have been widely used as photo‐catalysts . Also, up to know SCP are considered as a promising photo‐catalysts for degradation of organic dyes .…”

New host‐guest supramolecular coordination polymer catalyst 3∞[Co(μ2CN)5(CN)(μ2‐Me3Sn)2(Me3Sn)(H2O)(qox)], SCP1 (qox = quinoxaline) has been synthesized and characterized by single crystal X‐ray diffraction, FT‐IR, UV/Visible and fluorescence spectra, thermal and elemental analyses. The tin atoms act as bridges connecting the Co (CN)6 building blocks. The structure of SCP1 exhibits an unusual self‐coordinated host‐guest 3D network with qox as guest molecule. Also, the nanosized1\ was prepared under ultrasonic irradiation while the morphological features of both were examined by TEM and SEM. SCP1 and nanosized1\ are used as heterogeneous catalysts for removal of toxic dyes under UV and ultrasonic irradiation. The results show high effectively decolorized of indigo carmine dye (IC) without generation of any hazardous wastes or byproducts. The reaction is first order with respect to IC, while the factors affecting the rate constant of the degradation reaction are investigated. Mineralization of IC was investigated by IR and UV spectra. The trapping experiments were carried out to determine the role of active species used for degradation of the dye. The activation parameters of the reaction have been estimated and a possible mechanism of degradation was proposed and discussed in detail.

“…Nanostructured material and nanoparticles (NPs) have become fundamental components of nanotechnology and/or nanoscience in recent years due to their unique physicochemical properties that mostly include plasmonic, magnetic, electronic, size‐dependent optical, catalytic properties and potential applications . In fact, nanostructures possess high stability, tunable compositions, a high surface area, particular biological behaviors, and a wide range of physical multifunctionality . Nanostructured materials (NMs) that are used in agriculture, biosciences and the food industry comprise various types, such as carbons (e.g.…”

“…Nanostructured materials (NMs) that are used in agriculture, biosciences and the food industry comprise various types, such as carbons (e.g. graphene, nanodiamonds, fullerenes, carbon nanotubes, and carbon nitrides), composites, metal oxides, metals, organic and inorganic materials, among others . These NMs have a variety of dimensions, sizes, origins, compositions, and shapes based on the needed properties/features for the desired application and can be flat, hollow core, spherical, cylindrical, conical, spiral, tubular and/or irregular, ranging from 1 to 100 nm …”

Nanotechnology is currently being widely employed in agriculture and horticulture. The most widely investigated and developed factor related to fruit trees is nanofertilizers (NFs), which play very important roles in increasing vegetative growth, improving reproductive growth and flowering, thereby increasing productivity, product quality and ultimately increasing shelf-life and decreasing fruit waste. These nanomaterials, which are generally sprayed at low concentrations on trees at different time intervals and in frequent sessions, are also considered as growth stimulants. Macro-and micro-scale NFs such as zinc, boron, chitosan, and fertilizer nanocomposites such as ZnFeMnB (zinc, iron, manganese, boron), NPKMg (nitrogen, phosphorus, potassium, magnesium), and calcite have been shown to significantly improve the vegetative and reproductive traits of fruit trees such as pomegranate, strawberry, mango, date, coffee and grape. Knowledge on the effects of NFs on fruit trees and biological reasons for their effects on different traits is incomplete and there is an urgent need for extensive research on these topics.

“…The supports prevent agglomeration of NPs and increase their stability and efficiency. The resulting heterogeneous catalysts have many advantages over homogeneous metal catalysts, such as ease of handling, simple work‐up and recyclability . Therefore, many researchers are trying to develop a simple and green method to produce heterogeneous nanocatalysts.…”

A green palladium‐based catalyst supported on Artemisia abrotanum extract‐modified graphene oxide (Pd NPs/RGO‐A. abrotanum) hybrid material has been used as a recoverable and heterogeneous nanocatalyst for the catalytic reduction of various dyes, including methylene blue, methyl orange and rhodamine B, in the presence of NaBH4 as reducing agent in aqueous medium at room temperature. With the help of UV–visible spectroscopy, the catalytic reactions were investigated. According to the results, these reactions followed the pseudo‐first‐order rate equation.
