Summary: Metal oxide semiconductors have attracted increasing attention due to their excellent electrical and optical properties, low-cost fabrication, and good stability. In this study, two-dimensional CuO nanosheets were synthesized by annealing Cu-based metal-organic frameworks (Cu-MOFs) and broadband photoelectrochemical photodetectors (PDs) based on these nanosheets were demonstrated for the first time. The 2D CuO PDs exhibited a wide photoresponse range from 365 to 850 nm, with a responsivity of 2.7 mA/W and a response time of 60/400 ms, surpassing most existing 2D material-based PDs. Moreover, the CuO PDs showed outstanding multicycle stability and long-term stability for 1-month storage, outperforming other 2D material-based PDs reported to date. These results suggest great potential for 2D CuO nanosheets in underwater photodetection.

The PEC PDs show negative and positive photocurrents in the UV-vis and NIR, respectively. The light-induced photocurrent polarity-switching originates from the competition of different redox reactions at the photoelectrode/electrolyte interface. Furthermore, t-Se/InSe bipolar PEC PDs have good potential for encrypted optical communications.

Summary: In this study, a new off-on fluorescence strategy for the determination of Ag+ and S2O32- was developed using nitrogen-doped carbon dots (N-CDs). The synthesized N-CDs exhibited bright blue fluorescence and could be selectively quenched by Ag+ ions. The quenching effect showed a linear relationship and had a low detection limit. Furthermore, the fluorescence of the N-CDs-Ag+ system could be restored by adding S2O32-, making it a promising method for the detection of S2O32- ions. The N-CDs were successfully applied to analyze Ag+ and S2O32- in real samples with satisfactory recoveries.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
