“…Many research papers in which AuNPs have shown promising antimicrobial activities have highlighted a majority spherical shape character of the NPs. Nevertheless, rod-shaped, triangular, hexagonal, and cubic NPs have also been found as part of the obtained mixture [ 133 ]. Thangamani et al synthesized AuNPs using Simarouba glauca leaf extract.…”

Currently, metal nanoparticles have varied uses for different medical, pharmaceutical, and agricultural applications. Nanobiotechnology, combined with green chemistry, has great potential for the development of novel and necessary products that benefit human health, environment, and industries. Green chemistry has an important role due to its contribution to unconventional synthesis methods of gold and silver nanoparticles from plant extracts, which have exhibited antimicrobial potential, among other outstanding properties. Biodiversity-rich countries need to collect and convert knowledge from biological resources into processes, compounds, methods, and tools, which need to be achieved along with sustainable use and exploitation of biological diversity. Therefore, this paper describes the relevant reported green synthesis of gold and silver nanoparticles from plant extracts and their capacity as antimicrobial agents within the agricultural field for fighting against bacterial and fungal pathogens that can cause plant, waterborne, and foodborne diseases. Moreover, this work makes a brief review of nanoparticles’ contribution to water treatment and the development of “environmentally-friendly” nanofertilizers, nanopesticides, and nanoherbicides, as well as presenting the harmful effects of nanoparticles accumulation in plants and soils.

Recently, Liquified petroleum gas (LPG) attracts wide applications due to its high heating value and clean combustibility. An innovative approach to synthesis of LPG from syngas was established based on Fisher-Tropsch (F-T) technology. However, the conversion and selectivity are generally low with the classical catalysts. The hybrid system of methanol and zeolitebased catalyst was established as a potential approach to promote such a process. To strongly overcome the large demand of LPG and grasp the research work in this subject, a comprehensive review became necessary. LPG is basically produced from syngas through the direct method, where most recent studies lay on, and the indirect or semi direct approach. There were several factors affecting the process performance, which mainly are the reaction temperature, reaction pressure, type of the hybrid catalyst, carbon monoxide to hydrogen ratio, mixture flow rate, and time-on-stream of the reaction. The most common reaction conditions reported in the literature are 260-400 °C, 10-50 bars and H 2 to CO ratio of 2. However, the most important parameter considered was the catalyst, which is a key factor of interest. The two main issues controlling the catalyst performance were the synergetic effect between the two hybridized catalysts and the used type of zeolite. It was perceived that the higher the zeolite membered rings the better the LPG selectivity (i. e., BEA, and USY provided the higher LPG production rate).

“…Development of sustainable and cost-effective catalysts is crucial for fundamental investigation and producing fine chemicals, fuel, polymers, and pharmaceutical ingredients. In this context, Co-, [1] Ni-, [2] Rh-, [3,4] Ir-, [5] Pd-, [6] Pt-, [7] Ru-, [8] and Au [9][10] -based homogeneous catalysts are used to hydrogenate alkenes, N-heteroarenes, ketones, and nitroaromatics with optimum efficiency. For example, Jia and co-workers reported a Rh-based chiral diphenylphosphine ligand for the asymmetric hydrogenation of functionalized olefins.…”

Rh‐Complex Supported on Magnetic Nanoparticles as Catalysts for Hydroformylations and Transfer Hydrogenation Reactions

Herein, we describe a facile protocol for the phosphine complex of Rh anchored on the ultrasmall magnetic nanoparticles for transfer hydrogenation and hydroformylation reactions. A diphenylphosphino‐ferrocenylethyl amine was conjugated with dopamine hydrochloride to form dop‐Fc, which was then anchored on the surface of magnetic nanoparticles to produce Fe3O4@dop‐Fc. The prepared materials were complexed with a Rh precursor as a catalytic center. XRD, FTIR, SEM, TEM, and XPS were used to investigate the structure and its reactivity. Rh‐complexes of Fe3O4@dop‐Fc were used to convert terminal olefin to aldehyde using syngas (CO : H2 1 : 1) under pressure, obtaining up to 99% selectivity for branched aldehyde. The wide applicability of the Fe3O4@dop‐Fc−Rh construct was tested for the selective transfer hydrogenations of nitroarene and N‐heteroarene. Particularly, quinoline was quantitatively hydrogenated to 1,2,3,4‐tetrahydroquinoline(py‐THQ) using tetrahydroxydiboron (THDB). Also, the functional group tolerance in the reduction of nitroarene and styrene was evaluated. The robustness of the catalyst was tested by reusing it for multiple cycles.
