Fabrication of flower-like platinum clusters onto graphene sheets by pulse electrochemical deposition

The Liquid Phase Deposition of ZnPtBNs: Study on Structural, Morphology, and Their Sheet-Resistant

“…The finding is in a good agreement with FESEM analysis, where a concentration of 0.467 mM, the ZnPtBNs microstructure resulting from the fibrous flower form, leading the formation of larger an active surface area (Chen et al, 2011) and good electrical conductivity or lower sheet resistance (Yoon et al, 2008). These results are in line with an average diameter of ZnPtBNs, where it gradually increased with Zn(NO3)2,6H2O concentration, promoting the formation of ZnPtBNs which had a larger surface area at (111) crystal plane (Hsieh, Wei, Hsiao, & Chen, 2012).…”

Template‐free Electrosynthesis of Platinum Nano‐Cauliflowers for Catalysing Electron Transfer Reaction of Plutonium

“…However, the heterogeneous reduction of H 2 [Pt (IV) Cl 6 ] to Pt is different and especially in the presence of acids because HCl is produced as the reaction product after the deposition process [11][12][13]. Thus, the cyclic voltammogram (CV) of 10 mM H 2 PtCl 6 in 1 M HCl on ITO was studied carefully for a few initial cycles at the scan rate (υ) of 50 mV s À 1 to get an insight into the electrochemical phase-formation of Pt on ITO (Figure 1).…”

“…Although this process can produce metal nanoparticles of best possible chemical purity, the control of size and shape of nanoparticles is very challenging task as it depends on several parameters such as strategy of electrochemical synthesis [5,6], potential pulse parameters [7], nature of the substrate materials [8], and presence of any additional chemical reagents [9]. Different strategies had been adapted to date to prepare platinum nanoparticles of different sizes and shapes by employing cyclic voltammetry at constant scan rate [10] and potentiostatic pulses [11][12][13]. Further, it has been observed that the interfacial strain on the platinum nanoparticles supported on an oxide matrix can enhance its catalytic activity [14,15].…”

Efficient gas sensitivity in mixed bismuth ferrite micro (cubes) and nano (plates) structures

“…4(a) and (b)). In Bode plot, peak from higher frequency indicates interfacial layer of BFO/substrate and electrolyte/BFO, respectively [43,44]. Peaks of Pd-treated BFO film were at higher frequencies than pristine BFO film case indicating that the Pd-treatment shortened the electron lifetimes within BFO.…”
