Abstract Spontaneous noble metal dopant segregation in an oxide lattice can lead to the formation of metallic clusters and extended acicular inclusions. In a thin-film process, shape orientation such inclusions are governed by crystal growth direction, giving rise composite material with lattice-matched nanopillars embedded vertically insulating or semiconducting matrix. An interesting applicat...

Composite electrodes of polyaniline/MnO2-Multi walled carbon nanotube (PANI/MnO2-MWCNT), MnO2-MWCNT nanocomposites and MWCNT was produced by the in situ direct coating approach. The supercapacitor performance of the nanocomposites was studied by Fourier transform infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM). The electrochemical properties of electrodes were also investig...

Nanostructuring boron-doped diamond (BDD) films increases their sensitivity and performance when used as electrodes in electrochemical environments. We have developed a method to produce such nanostructured, porous electrodes by depositing BDD thin film onto a densely packed "forest" of vertically aligned multiwalled carbon nanotubes (CNTs). The CNTs had previously been exposed to a suspension ...

TiO2 anatase nanowires have been prepared by a hydrothermal process followed by post-heat treatment in air. TiO2 nanoparticle/TiO2 nanowire composite electrodes were prepared for dye-sensitized solar cells (DSC) in order to improve light-to-electricity conversion efficiency. The TiO2 NP/TiO2 NW composite cells showed higher DSC performance than ordinary nanoparticle cells and fully nanowire cel...

Composite graphite/silicon (Si) electrodes with low Si weight percentages are considered as a promising anode for next generation Li-ion batteries. In this context, understanding the mesostructural changes due to volume expansion and complex electrochemical interplay between graphite becomes crucial unlock real-life applications of such composite electrodes. This work presents, first time, thre...
