Summary: In this work, a quasi-ternary Z-scheme heterojunction photocatalyst (CQD/CdS/g-C3N4) was successfully constructed, and its electron transfer path was elucidated. The built-in electric field at the interface between CdS and g-C3N4 induced the separation of excitons, while the energy barrier between CQD and CdS accelerated charge transfers and prevented exciton annihilation. As a result, CQD/CdS/g-C3N4 exhibited the best photocatalytic degradation performance.

Summary: Chemically bonded BiVO4/ZnO quantum dot heterostructures were fabricated using a simple solution dry-out method, forming chemically bonded interfaces (CBIs) that promote photoexcited electron transfer and serve as hole-blocking layers. The CBIs showed excellent performance in both UV and visible light regions, leading to significantly increased photocurrent density in BiVO4/ZnO QDs without a cocatalyst. Additionally, ethylene glycol was found to partially reduce Bi ions to elemental bismuth during the calcination process, contributing to improved water oxidation kinetics.

Summary: This study developed hard segment functionalized polyurethane ionomers as gel polyelectrolytes for quantum dot sensitized solar cells, achieving high photovoltaic conversion efficiency. The hole extracting capacity of the redox active group was controlled by adjusting the chemical and electronic environment. The effects of the structure of the hard segment on photovoltaic performance were thoroughly investigated, and it was found that the conductivity and thermal stability could be improved by functionalizing the polyurethane chain extenders and tuning the redox potentials. The experimental results demonstrate that high photovoltaic conversion efficiency can be achieved by selecting appropriate combinations of ionomers and hole conducting environments.

Summary: Rational design of heterostructures is an effective strategy for enhancing the photocatalytic activity of semiconductors. In this study, a dual Z-scheme CdS/ZWO/ZnS heterojunction photocatalyst was synthesized by assembling zero-dimensional CdS and ZnS quantum dots onto one-dimensional ZnWO4 nanorods. The photocatalytic experiments demonstrated that the dual Z-scheme heterojunction photocatalyst exhibited significantly higher photodegradation activity compared to individual CdS, ZnS, and binary CdS/ZWO and ZnS/ZWO heterojunctions. The characteristics and photocatalytic mechanism of the CdS/ZWO/ZnS photocatalysts were investigated using various measurement techniques and computational calculations.

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: 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.
