Novel strategy for high-performance supercapacitors through the polyvinylpyrrolidone (PVP)-assisted in situ growth of FeS₂

Abstract

Iron disulfide or pyrite (FeS2) has emerged as a promising transition metal sulfide-based supercapacitor owing to its abundance and superb electrochemical properties.

Two birds with one stone: facile fabrication of an iron–cobalt bimetallic sulfide nanosheet-assembled nanosphere for efficient energy storage and hydrogen evolution

“…Rapid economic and social development often leads to the excessive consumption of fossil fuels, resulting in severe environmental pollution and ecological crises. [1][2][3] Consequently, the use of clean energy to replace traditional fossil fuels has become an inevitable trend, necessitating the development of novel energy storage devices. 4,5 Supercapacitors, known for their high energy density, fast charging and discharging capabilities, and long-term cycling stability, have been identified as reliable energy storage devices.…”
