Summary: A Sn/g-C3N4 composite was synthesized via a facile chemical reduction method, with well-dispersed Sn nanoparticles on the porous g-C3N4 framework. The composite was used as an anode material for Lithium-ion batteries, exhibiting significantly improved cycling performance compared to pure Sn. This improvement can be attributed to the significant contribution of the g-C3N4 support in preventing volume change during the lithiation/delithiation process of Sn.

Summary: Tin has been considered as an ideal anode material for lithium ion batteries due to its high theoretical capacity, but its practical application is limited by poor cycling stability. Different structures, such as amorphous and crystalline, can significantly impact the electrochemical performance of Sn-based electrodes. In this study, it was found that the amorphous-Sn@C electrode exhibited higher capacity, better cycling stability, and rate capability compared to the crystalline-Sn@C electrode, attributing to enhanced strain regulation and defect sites. The results could serve as a reference for the development of high-capacity and long cycle life alloy-based anodes for lithium ion batteries.

Summary: Developing insertion-type anodes is crucial for the advancement of rocking chair zinc-ion batteries, but there are only a few reported examples of such anodes. This study focuses on Bi2O2CO3 as a high-potential anode with a unique layered structure. By doping Ni into Bi2O2CO3 nanosheets and designing a free-standing electrode with Ni-Bi2O2CO3 and CNTs, the researchers were able to improve charge transfer and enhance the electrochemical reversibility and structural stability of the material. The optimized electrode exhibited a high specific capacity, suitable average discharge voltage, and long-term cycling stability, making it a promising candidate for high-performance anodes in zinc-ion batteries.

Summary: In this study, a CO2 sensor capable of low-temperature operation was fabricated using an open-channel-type thin-film transistor structure with a polar surface of an oxide semiconductor. The sensor showed a sensitivity 2.9 times greater than that under an inert N2 atmosphere at an operating temperature of only 150 degrees C. The results suggest that TFTs fabricated with polar surfaces of oxide semiconductors are useful for gas-sensing applications.

Summary: In this study, a defective system of V-doped Fe2O3 with Pt as a cocatalyst was used for photoelectrochemical water oxidation. The defects in the VFPt-2.5 photoanode were characterized by XPS and EPR analyses. The SEM and TEM analyses revealed that the electrodeposited V-doped alpha-Fe2O3 had a nanosized morphology with an average diameter of 12 nm and a thickness of 300 nm. Under light irradiation, the VFPt-2.5 photoanode achieved a remarkable onset potential and photocurrent density. The stability test showed that Pt helped overcome the charge recombination caused by surface states.
