Nanocomposites of Conducting Polymers and 2D Materials for Flexible Supercapacitors.

Flexible supercapacitors (FSCs) with high electrochemical and mechanical performance are inevitably necessary for the fabrication of integrated wearable systems. Conducting polymers with intrinsic conductivity and flexibility are ideal active materials for FSCs. However, they suffer from poor cycling stability due to huge volume variations during operation cycles.

High-performance photocatalytic reduction of Cr(VI) using a retrievable Fe-doped WO/SiO heterostructure.

The enhancement of the photocatalytic performance of pristine WO was systematically adjusted due to its fast recombination rate and low reduction potential. A designed heterostructure photocatalyst was necessarily synthesised by Fe metal ions doping into WO structure with and composition modification. In this study, we synthesised a retrievable Fe-doped WO/SiO heterostructure using a surfactant-assisted hydrothermal method.

Enhanced visible-light photocatalytic activity of g-C3N4/TiO2 films.

Enhanced photocatalytic degradation of methylene blue (MB) using graphitic carbon nitride/titanium dioxide (g-C3N4/TiO2) catalyst films has been demonstrated in this present work. The g-C3N4/TiO2 composites were prepared by directly heating the mixture of melamine and pre-synthesized TiO2 nanoparticles in Ar gas flow. The g-C3N4 contents in the g-C3N4/TiO2 composites were varied as 0, 20, 50 and 70 wt%.
