Journal ArticleDOI
Facile Route to an Efficient NiO Supercapacitor with a Three-Dimensional Nanonetwork Morphology
TL;DR: This study indicates that forming a 3D nanonetwork is a straightforward means of improving the electrochemical properties of a supercapacitor.
Journal ArticleDOI
Three-dimensional nano-foam of few-layer graphene grown by CVD for DSSC
TL;DR: The use of 3D-NFG, with the advantage of large surface area and high conductivity, as an alternative to the Pt counter electrode material in dye sensitized solar cells is investigated and suggests a great potential for interconnected graphene networks in electronic devices and photocatalytic sensors as well as in energy-related materials.
Journal ArticleDOI
Realization of high performance flexible wire supercapacitors based on 3-dimensional NiCo2O4/Ni fibers
TL;DR: In this article, the authors have successfully fabricated highly porous, binder free three-dimensional flower-like NiCo2O4/Ni nanostructures on Ni-wire as a fiber electrode for high-performance flexible fiber supercapacitors.
Journal ArticleDOI
A Titanium-Doped SiOx Passivation Layer for Greatly Enhanced Performance of a Hematite-Based Photoelectrochemical System
TL;DR: Great potential is shown of the use of the Ti-doped SiOx layer with a synergistic effect of decreased charge recombination, the increased number of active sites, and the reduced hole-diffusion pathway from the hematite to the electrolyte.
Journal ArticleDOI
Nanoporous hematite structures to overcome short diffusion lengths in water splitting
TL;DR: In this paper, a nanoporous haematite (α-Fe2O3) structure using boric acid (H3BO3) treatment was proposed to solve the issue of the short diffusion length of carriers in α-Fe 2O3 for photoelectrochemical (PEC) applications.
