Summary: In this study, a stretchable, foldable, and flexible commercial sponge has been converted into a conducting material by incorporating polypyrrole (PPy). Bismuth oxide (Bi2O3) electrode material with a wool ball-like morphology is synthesized over PPy-coated sponge, creating a hybrid Bi2O3@PPy electrode. The unique morphology of Bi2O3 and the porous structure of PPy@sponge result in a high number of active sites and short diffusion pathways, enabling efficient electron-ion transportation. A pencil-type asymmetric supercapacitor using Bi2O3@PPy//graphite rod electrodes delivers high energy and power densities, as well as excellent cycling stability.

Summary: In this study, the photocatalytic activity of a Cu2SnS3 (CTS) and graphene oxide (GO) composite, CTS + GO, was studied for the degradation of Navy Blue (NB) ME2RL reactive azo dye. The synthesized composite was evaluated for its structural, morphological, and optical properties. Compared to pure CTS, the CTS + GO nanocomposite showed enhanced photocatalytic activity, attributed to reduced charge carrier recombination, improved visible light absorption, and modified dye absorption through GO amalgamation in CTS. The simple and well-organized chemical bath method used for catalyst preparation is more suitable for industrial production.

Summary: The successful deployment of sodium-ion batteries requires high-performance, sustainable, and cost-effective anode materials with a high current density. In this study, sodium disulphide (NiS2) was prepared as a composite with activated carbon (C) using a hydrothermal synthesis route. The NiS2/C composite exhibited well-defined diffraction peaks of NiS2 in the X-ray diffraction pattern, and had a surface area close to 148 m^2 g^-1 according to the Brunauer-Emmett-Teller (BET) study. With a current density of 50 mA g^-1, the NiS2/C composite showed a high capacity of 480 mA h g^-1 during the initial cycle, which decreased to 333 mA h g^-1 after 100 cycles. It also demonstrated exceptional rate capability, delivering a capacity of 270 mA h g^-1 at a high current density of 2000 mA g^-1. Ex situ X-ray absorption near edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) analyses provided insights into the chemical bonding and changes during electrochemical redox cycling, improving the understanding of the sodium storage mechanism and offering guidance for developing high-performance electrode materials for rechargeable sodium-ion batteries.
