Electrostatic Assembly of Platinum Nanoparticles along

Aug 24, 2017 Therefore, the as-synthesized negative-charged platinum nanoparticles (PtNPs) could be conjugated onto the positive-charged PAN/APS nanofibers through the electrostatic interaction (Figure 1 B). To fabricate an electrochemical sensor, the created PAN–PtNPs hybrid nanofibrous membrane was further utilized to modify a glassy carbon electrode (GCE), as indicated in Figure 1 C

Oct 19, 2015 Platinum (IV) hexachloride (PHC) is one of the precursors commonly used to synthesize these catalysts [12–14]. A number of studies published over the years utilizing strong electrostatic adsorption (SEA) have demonstrated that the PHC precursor yields highly dispersed, ultra-small Pt particles on alumina and carbon [9, 15, 16]. The use of PHC, however, involves minor inconveniences
