Catalytic reduction of 4-nitrophenol using gold-silver alloy nanoparticles coated on alkali activated sand

Gamma Irradiation-Assisted Synthesis of Silver Nanoparticle and Their Antimicrobial Applications: A Review

“…The addition of supports is highly recommended to prevent agglomeration and as a stabilizer by providing a barrier and in controlling both the size and shape, and the final distribution of NPs [85][86][87]. The selection of the support material is critical as it may enhance or reduce the efficiency of Ag-NPs [88,89]. Many researches focused on the stabilization of Ag on adsorbent materials, including cellulose fiber [90], polyethersulfone microfiltration membranes [91], clay [92], and activated carbon [93].…”

Gold (Au), Silver (Ag) and Bimetallic Au/Ag Core-Shell Nanoparticles: Synthesis and Applications in 4-Nitrophenol Reduction Reactions

“…Gold (Au) and silver (Ag) plasmonic nanoparticles are nanomaterials with unique optical and electronic properties, which open up many opportunities in practical biomedical applications, such as therapeutic, diagnostic, and sensing applications (Feng et al, 2019;Das et al, 2011;Bijalwan et al, 2019). These nanoparticles have been studied very well and in detail, especially regarding the effect of size modification on plasmon absorption due to its catalytic activity (Link et al, 1999).…”

“…These nanoparticles have been studied very well and in detail, especially regarding the effect of size modification on plasmon absorption due to its catalytic activity (Link et al, 1999). Furthermore, metal nanoparticles can be deposited on various supports to establish a better overall efficiency of the catalytic process (Bijalwan et al, 2019) where the surface-tovolume ratio is high (Ahmad et al, 2019). In more detail, the application of gold nanoparticles (AuNP) is extended to various biomedical fields, such as biosensors, clinical chemistry, immunoassays, genomics, photo-thermolysis of cancer cells, detection and control of microorganisms, targeted drug delivery, optical imaging and monitoring of biological cells and tissues by utilizing resonance scattering or in vivo photoacoustic technique (Bijalwan et al, 2019;Jiang et al, 2020).…”

“…Nanoparticles derived from gold have medical and pharmaceutical applications (Shen et al, 2017). Because of their excellent ability to penetrate intercellular spaces, gold nanoparticles are used as carriers in cancer diagnosis (Bijalwan et al, 2019).…”
