“…The strong peak at 1561 cm −1 and weak peaks at 1404 and 1349 cm −1 of the PPy@PHSi nanocomposite are assigned to C=C backbone stretching and ring stretching of PPy, respectively. The peak at 1045 cm −1 belongs to the C–H in‐plane bending of PPy, while those at 967 and 926 cm −1 are attributed to in‐plane deformation of the ring . Compared with those of pure PPy and PHSi, the bands of PPy@PHSi nanocomposite are shifted slightly.…”

Uniform porous silicon hollow nano-spheres are prepared without any sacrificial templates through a magnesio-thermic reduction of mesoporous silica hollow nanospheres and surface modified by the following in situ chemical polymerization of polypyrrole. The porous hollow structure and polypyrrole coating contribute significantly to the excellent structure stability and high electrochemical performance of the nanocomposite.

High‐lateral resolution X‐ray fluorescence microspectroscopy and dynamic mathematical modelling as tools for the study of electrodeposited electrocatalysts

In this paper, we report on the use of high-space resolution soft X-ray fluorescence microspectroscopy for the study of electrodeposited composites containing catalytic ternary metal nanostructures. X-ray fluorescence maps are interpreted in terms of a dynamic mathematical model of the electrode morphology and metal space distribution, allowing to reproduce the observed space patterns and electrochemical transients by assigning an appropriate set of electrokinetic parameters. The discussed materials-science case is the electrochemical growth of a Mn-Mg-Cu-polypyrrole nanocomposite electrocatalyst material -free of expensive Pt and environmentally unfriendly Co -with promising performance for fuel-cell oxygen electrodes. The synergy of high-resolution compositional mapping with electrokinetic modelling not only provides the general rationale for quantitative use of potentially large compositional distribution datasets but also yields unprecedented insight into the specific catalyst synthesis process. The expounded application is just a prototypical case study of a more general approach, which can be employed for the understanding of electrochemical material science processes, both in situ and ex situ, as well as for the characterisation of the corresponding products, with no other limitations in principle than X-ray transmission and beam damage.

“…Nam et al synthesized SnO 2 -polypyrrole hybrid nanowires by a simple electrochemical method. The different reaction speed of the electropolymerization and the chemical deposition reaction caused the incorporation of uniformly dispersed SnO 2 nanoparticles inside polypyrrole nanowires and the better electrochemical performance was achieved [17]. But in this paper, PPy nanowires playing as a protective role were located on the surface of SnO 2 slices.…”
