Simple preparation of Pd-NP/polythiophene nanospheres for heterogeneous catalysis

Ultrafine Pt Nanoclusters Confined in a Calixarene-Based {Ni24} Coordination Cage for High-Efficient Hydrogen Evolution Reaction

“…Then, Pt­(IV) species were gradually reduced to Pt(0) atoms through the electron transfer between metal and the surrounding organic groups of CIAC-121 . Note that, similar to the previous reports, the ligands of H 2 TDC and thiophene in the present study can serve as reducing agents for the formation of Pt clusters . The formed Pt(0) atoms spontaneously collapsed and grew into Pt NCs.…”

Fabrication of noble metal (Au, Ag, Pt)/polythiophene/reduced graphene oxide ternary nanocomposites for NH3gas sensing at room temperature

“…4(C)) ternary nanocomposite showed no obvious diffraction peak. This result was related to the small size of the synthesized Pt nanoparticles, 38 and an incomplete reduction of the PtCl 4 2− ion because rGO prevented the further growth of the PTh-surrounded Pt nanoparticles. 39,40…”

“…Then, the radical cations underwent a multiple polymerization reaction via a repeated cycle of oxidation, polymerization and deprotonation to form PTh. 38,39 According to the standard reduction potential, AuCl 4 − is reduced at a potential of 1.002 V, which is higher than that of Ag + (0.8 V) and PtCl 4 2− (0.73 V). Therefore, the reduction and nucleation of AuCl 4 − at the sites of PTh was faster and more efficient than that of Ag + and PtCl 4 2− .…”

Direct deposition of copper nanoparticles on poly(glycidyl methacrylate) beads

“…Copper nanoparticles (CuNPs) have gained considerable attention due to its useful properties such as catalytic, antibacterial activity, good thermal and electrical conductivity at a low cost compare to noble metal nanoparticles (Ag, Pd, Pt, Au). In the literature, the noble metal nanoparticles have been found to be used widely as a catalyst . Not only these, the CuNPs have also been used in catalysis , antimicrobial film , and so on.…”

“…Wang et al demonstrated a simple, one‐step route for assembling Au nanoparticles on N‐containing polymer nanospheres (resorcinol–melamine–formaldehyde resin nanospheres) through in situ reductive growth process . Bae et al developed a simple method of preparation for catalytically active Pd‐nanoparticles decorated on polythiophene conducting polymer nanospheres by the chemical reduction . Similarly, for the first time Ali et al introduced Au nanoparticles into the polyquinoline conjugated polymer .…”
