Summary: Black phosphorus and graphite-like carbon nitride were combined to prepare a hybrid nanostructure with excellent flame-retardant properties for EP/BP-CNx nanocomposites. The addition of 2% BP-CNx significantly reduced peak heat release rate and total heat release of the composites, while increasing LOI value. Adjusting the proportion of BP and CN showed different influences on the fire performance of the matrix.

Summary: Black phosphorus, a significant 2D material, tends to degrade under ambient conditions. This paper presents a more ambitious approach to improve the stability of black phosphorus by blocking oxidation and repairing it using the antioxidant molecule beta-carotene. The study suggests the potential of using natural antioxidant molecules to enhance the stability of other environmentally sensitive nanomaterials for technological and consumer applications.

Summary: The research reveals that the optical anisotropy of oxidized BP is less sensitive compared to its electrical conductivity, and the low coverage of the initial oxidized layer allows the optical properties to remain constant for days. As the oxidation layer grows and forms an effective layer, modulation of the total optical anisotropy through optical interference may result in increased or decreased optical anisotropy.

Summary: The protection mechanism of N,N-dimethylformamide (DMF) on few-layer black phosphorus (LBP) was investigated. It was found that DMF impedes the hydrolysis of phosphorus oxides, leading to a lower generation of soluble phosphorus compared to the absence of DMF. Insoluble phosphorus oxides were also observed in DMF-exfoliated LBP solution, providing further evidence for the hydrolysis impeding mechanism. This finding sheds light on the protection effects of DMF on LBP and contributes to the development of effective stabilization technologies.

Summary: In this study, P-doped CN photocatalyst with high efficiency for H2O2 production was successfully synthesized using a simple one-step calcination method. The mechanism of H2O2 production over P-CN was revealed through density functional theory calculations, showing that P-doping promotes the adsorption of O-2 on CN and enhances the formation of intermediate products. Experimental results confirmed that P-doping suppresses electron and hole recombination, leading to improved photocatalytic performance of P-doped CN.
