Fabrication of highly dispersed Pd nanoparticles supported on reduced graphene oxide for catalytic reduction of 4-nitrophenol

Size-Dependent Catalytic Activity of PVA-Stabilized Palladium Nanoparticles in p-Nitrophenol Reduction: Using a Thermoresponsive Nanoreactor

“…10−20 Therefore, Pd NPs stabilized by suitable templates with advanced catalytic activity have attracted growing attention owing to their unique properties and great potential in the field of catalysis. 21 Lu and co-workers reported thioether-containing covalent organic framework (PtNPs@ COF and PdNPs@COF) nanocomposites that showed excellent catalytic activities toward Suzuki−Miyaura coupling reactions and reduction of p-nitrophenol (p-NP) under an ambient condition. Moreover, these COF-template-supported ultrafine nanocomposites are highly stable and reusable without loss of catalytic activity.…”

Pd-Nanoparticles@layered double hydroxide/reduced graphene oxide (Pd NPs@LDH/rGO) nanocomposite catalysts for highly efficient green reduction of aromatic nitro compounds

“…42 However, it is noteworthy that like bare ZnAl-LDH, the synthesized rGO exhibits no catalytic activity towards the reduction of nitrophenol, as evidenced by the unaltered peak at 400 nm. 43 The high adsorption of 4-nitrophenol on the Pd NPs@LDH/rGO nanocomposite increases the catalytic activity towards the hydrogenation reaction. Furthermore, the catalytic activity significantly increases with an increase in the rGO content up to 10 wt% [Pd NPs@LDH/rGO(10%)].…”

Selenium and nitrogen co‐doped porous carbon immobilized Ag nanoparticles: A practical heterogeneous nanocatalyst for hydrogenation of nitroaromatics

“…[7] Among these techniques, catalytic hydrogenation of nitroaromatics into amines is an efficient, simple, and industrially important method, because the relevant products are versatile intermediates and building blocks for the synthesis of polymers, agrochemicals, pharmaceuticals, dyes, pigments, and analgesic and antipyretic drugs. [8][9][10][11][12] Noble metal nanoparticles (NPs) and their alloys are usually exploited as efficient catalysts for this reaction. [13][14][15] Among them, Ag-based nanocatalysts (Ag NPs) have received particular attention from the synthetic organic chemist's community owing to their antibacterial and antifungal properties, good conductivity, stability, biocompatibility, high catalytic efficiency, and especially lower cost in comparison with other noble metals (Au, Pd, Pt, and Ru).…”
