Abstract

Here we report the synthesis and characterization of graphene oxide anchored Pd–Cu bimetallic nanoparticles by bio reduction method and its application in Sonogashira cross-coupling reaction.

Visible Light Response Photocatalytic Performance of Z-Scheme Ag3PO4/GO/UiO–66–NH2 Photocatalysts for the Levofloxacin Hydrochloride

“…For GO, the XRD pattern reveals a characteristic reflection peak at 2θ = 9.88°. 43 With regard to pure Ag 3 PO 4 , the diffraction peaks around 20.87, 29.69, 33.28, 36.56, 47.78, 52.68, 55.00, 57.27, 61.64, and 73.86°correspond to (110), ( 200), ( 210), ( 211), (310), ( 222), (320), ( 321), (400), and (332) planes of the cubic crystal phase Ag 3 PO 4 (JCPDS card no. 06-0505).…”

Organometallic interactions between metal nanoparticles and carbon-based molecules: A surface reactivity rationale

“…Similar catalytic behavior was also observed for Pd-Cu nanoalloys anchored on graphene oxide. 93 Regarding gold-based catalysts, Lambert and co-workers demonstrated that supported zero-valent gold nanoparticles catalyzed the cross-coupling between iodobenzene and phenylacetylene, 94 in contrast to the lack of activity shown by Au(I) and Au(III) supported materials. 95 It was proven that some leaching of ionic gold species into the liquid phase during the coupling happened, but this phase did not exhibit any catalytic activity, indicating that the Sonogashira reaction shows a surface-like reactivity.…”

Studies on the Antioxidant and Antibacterial Activities of In Situ Green Synthesized Graphene‐Gold Nanocomposite

“…[4] Accordingly, graphene incorporated with several metals (Ag, Cu, Pd, Zn, Mn, Fe, Ni, Pt, Cd, Co etc.) to produce variety of green synthesized NCs [5][6][7][8][9][10][11][12] that found large scope for research in catalytic reduction, [13] photocatalytic dye degradations, [14][15] electrochemical capacitors, [16] electrocatalyst, [17] supercapacitors, [18] and biological applications like antibacterial, [5][6][7][19][20][21] antioxidant, [21] antimicrobial activities [8-9,22,] with enhanced performances.…”
