“…In contrast, in the presence of the catalyst, the reduction was completed in 105 s with the optimum parameters of 250 mM NaBH 4 and 10.0 mg AgNPs. As comparison, the reduction of 4‐nitrophenol can also be achieved by employing gum acacia‐Pt nanoparticles, resin‐Au nanoparticles, Ni‐polyvinylamine/SBA‐15 composite, AgNP‐seashell, and silver/TiO 2 nanocomposite with complete reduction taking 8 h, 20 min, 85 min, 4.5 m, and 2 min, respectively . In terms of time, AgNPs‐peach kernel shell is the best among the aforementioned proposed catalysts.…”

“…In terms of time, AgNPs‐peach kernel shell is the best among the aforementioned proposed catalysts. In addition, their nanoparticles have been found to reduce methyl orange faster than Cu nanoparticle‐mesoporous silica SBA‐15, AgNP‐seashell, and silver/TiO 2 nanocomposite . Similar finding was found when the nanoparticles were applied to reduce methylene blue more efficiently compared to AgNP‐seashell, porous Cu microspheres, and silver/TiO 2 nanocomposite …”

Silver nanoparticles (AgNPs) are intensively investigated for their superior physical, chemical, and biological properties. A proper knowledge of these properties is essential to maximizing the potential applications of AgNPs in several areas while minimizing their risks to humans and the environment. This paper aims to critically review AgNPs from the perspectives of research trends, global consumption, synthesis, properties, and future challenges. Generally, AgNPs can be synthesized using three methods, namely physical, chemical, and biological, and the related works as well as their numerous advantages and disadvantages are presented in this review. In addition, AgNPs can be potentially explored for various applications. Future challenges on (AgNP) synthesis, their release into the environment, and scaling up production, as presented in the review, suggest that several potential topics for future works are available to promote a safer and more efficient use of these nanoparticles. Studies on AgNPs in Malaysia have increased since the Malaysian government officially established a directorate for nanotechnology development. This calls for a proper set of policies on AgNPs starting from their production to utilization as well as their effects on various related industries and the environment.

“…Our strategy entailed the generation of palladium nanoparticles (Pd NPs) using Cucurbita pepo leaf extract. In view of the high propensity of metal NPs to agglomerate, solid supports have been usually applied [44,45,46,47,48] which in this study was replaced by coral reef to anchor Pd NPs. Thus, biogenically synthesized Pd/coral reef nanocomposite, assembled by a facile and eco-friendly method, has been introduced in this unprecedented cyanation reaction using a plant extract.…”

A simple procedure for the palladium-catalyzed cyanation of aryl halides is described via a nucleophilic non-toxic cyanide source, K4[Fe(CN)6] in the presence of Pd/coral reef nanocomposite as a heterogeneous catalyst; the protocol provides a useful and easy method for the synthesis of aryl nitriles that are generated from the corresponding variant aryl halides, with sodium carbonate as a base. The nanocatalyst was prepared by a biological process using aqueous extract of leaves of Cucurbita pepo as a stabilizing and reducing agent and coral reef as a natural support, without deploying any hazardous chemicals. The catalyst, that is easily separable from the reaction mixture and reused multiple times, was characterized by FT-IR (Fourier-Transform Infrared Spectroscopy), ICP-AES (Inductively Coupled Plasma Atomic Emission Spectroscopy), XRD (X-ray Diffraction), TEM (Transmission Electron Microscopy), FE-SEM (Field Emission Scanning Electron Microscopy), EDS (Energy Dispersive X-ray Spectroscopy) and elemental mapping.

“…Metal/support NPs are generally synthesised by solvothermal process, chemical reduction method and sol-gel technique [16][17][18][19][20]. However, these methods are extremely costly and also involve application of hazardous chemicals such as hydrazine and N,Ndimethylformamide, all of which are highly reactive and have potential environmental and biological risks [16][17][18][19][20].…”

A facile and green synthesis of the Ag/ZnO nanocomposite by extract of Valeriana officinalis L. root in the absence of any stabiliser or surfactant has been reported in this work. The green synthesised Ag/ZnO nanocomposite was characterised by Field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), elemental mapping, Fourier-Transform infrared (FT-IR), X-ray diffraction analysis (XRD) and UV-Vis spectroscopy. According to SEM and TEM images, the Ag and ZnO particles are spherical with diameters of less than 20 and 40-50 nm, respectively. The Ag NPs/ZnO nanocomposite proved to be an effective catalyst in the reduction of various dyes including methyl orange (MO), Congo red (CR) and methylene blue (MB) in the presence of NaBH 4 in aqueous media at ambient temperature. A maximum degradation (100%) of dyes was performed using Ag/ZnO nanocomposite. The extraordinary performance of the prepared Ag/ZnO nanocomposite is attributed to the synergetic effect induced by both ZnO and Ag NPs in the catalytic degradation of organic dyes. The catalyst could be reused and recovered several times with no significant loss of catalytic activity.
