FeS₂ and WO₃ nanoparticles decorated on biochar as a high throughput electrode for supercapacitors

Abstract

The need for cutting-edge energy storage technologies, such as supercapacitors, has been enhanced tremendously to meet the demands of the growing population and depleting fossil fuel reserves.

Synergistic effect of heterointerface engineering and oxygen vacancy in electro-spun polymer fibres derived carbon-supported 1D hierarchical WO3/SnO2 nanostructures for high-performance supercapacitor devices

“…S7a†). 57 The highest specific surface area (SSA) of 23.1 m 2 g −1 was observed for WO 3 /SnO 2 @C, which might be due to the hierarchical morphology generated with the introduction of WO 3 and SnO 2 in the composite. 62,63 The BJH pore size distribution plots (Fig.…”

“…This shift in XPS peak positions establishes an interface between WO 3 and SnO 2 in WO 3 /SnO 2 @C as the contribution from the carbon support towards the peak shift is identical in all the samples. 57 The peak positions are listed in Table 1. Further, the nature of oxygen bonding in the samples was revealed by O 1s CL spectra, which are deconvoluted into three peaks within 529–534 eV (Fig.…”
