Click-Chemistry-Mediated Synthesis of Silver Nanoparticle-Supported Polymer-Wrapped Carbon Nanotubes: Glucose Sensor and Antibacterial Material

“…Metal nanoparticles (NPs) have received a great deal of attention owing to their great applications in various fields including solar cells, − optical devices, , and catalysis. − Among them, silver nanoparticles (AgNPs) have been gaining more consideration and becoming one of the potential candidates in not only catalysis (thermal-, electro-, and photo-) but also antimicrobial therapy. − However, one of the major drawbacks for wide applicability of AgNPs is their tendency to agglomerate and thus form larger particles owing high surface energy . To overcome this problem, various techniques have been proposed to control the size and stabilization of NPs during the formation process, such as inert gas condensation and cocondensation and use of surfactants, protecting agents, , polymeric ligands, , and biological templates. , Importantly, the activity of the resulting material depends on the size of the NPs as well as their preparation techniques. − Deposition of NPs onto a solid support is one of the important and mostly used strategies.…”

One-Step Electrochemically Prepared Bionic Hierarchical Nickel Black@Graphene Composite Membrane for Desalination by Solar–Thermal Energy Conversion

“…6−8 Currently, photothermal conversion materials mainly include plasmonic metal materials, 9 carbon-based materials (including graphene, 10 carbon nanotubes, 11 carbonized biomass materials 12 ), conductive polymers, 13 and narrow-bandgap semiconductors. 14 Among them, plasmonic noble metals (Au, 15,16 Ag 17 ) are the most extensively researched because the strong plasmonic responses coincide with the solar spectrum. The abundance of nickel in nature makes it an alternative choice for applications in plasmon-enhanced solar absorption.…”

“…Currently, photothermal conversion materials mainly include plasmonic metal materials, carbon-based materials (including graphene, carbon nanotubes, carbonized biomass materials), conductive polymers, and narrow-bandgap semiconductors . Among them, plasmonic noble metals (Au, , Ag) are the most extensively researched because the strong plasmonic responses coincide with the solar spectrum. The abundance of nickel in nature makes it an alternative choice for applications in plasmon-enhanced solar absorption. , Being a carbon-based material, graphene exhibits exceptional photothermal properties and broadband absorption capabilities, making it a highly promising candidate for photothermal conversion. , Under the irradiation of sunlight, the excited electrons of plasmonic metal nanoparticles are nonradiatively damped by a Landau damping mechanism and redistribute their energy to generate heat through electron–electron and electron–phonon scattering processes, whereas the solar absorption of carbon materials involves the excitation and relaxation of electrons and the thermalization of photoexcited electrons caused by electron–electron and electron–phonon scattering .…”
