To tackle this challenge, we utilized a high-temperature phosphorization technique to synthesize a composite material consisting of RuP₂ and CoP on the surface of hollow carbon spheres, resulting in a structure denoted as RuP₂/CoP@NPC. The integration of RuP₂ and CoP active components at the nanoscale level facilitated efficient charge transfer, which in turn optimized the electronic properties and catalytic performance of the catalyst. The experimental data indicated that the RuP₂/CoP@NPC catalyst displayed exceptional platinum-like activity and outstanding stability for hydrogen evolution reactions across a broad pH spectrum. Additionally, the mass activity of the catalyst was found to be roughly 6.3 times greater than that of the single-component RuP₂@NPC, highlighting the substantial improvement in the intrinsic HER activity.

The hydrogenation was achieved by thermal annealing of samples at temperatures of 200, 300, 400, and 550 °C in a pure hydrogen environment with a flow rate of 100 sccm for 30 min. RBS revealed that the multilayers are thermally stable, showing no sign of intermixing of layers up to 600 °C. It revealed the presence of oxygen in all the layers with a significant amount. ERDA revealed that a significant amount of H was near the surface and dropped towards the bulk of the samples, which is the middle layers (V and Ti layers) location. The probing towards the inner last layer (buried ZrC layer) of the multilayer stack showed an increase in the H amount detected. H amount decreased as the oxygen amount was increased in the layers indicating the negative impact of oxygen in the system, such that the total H amount in the samples with the TiO (1:1) and VO (1:1) was 99.122 at.% at 200 °C while that of Ti₂O₃ (2:3) and V₂O₃ (2:3) was 60.016 at.% at 300 °C indicating a significant change. The optimum temperature for the highest H amount observed was found to be between 200 °C and 300 °C. The as-deposited sample only showed the surface H, which is normally due to the atmosphere's hydrocarbons. The Raman spectroscopy results indicated that there was a significant decrease in the intensity of the D and G peaks due to annealing in a hydrogen environment. This suggests that the extent of hydrogen absorption, which occurs predominantly in the temperature range of 200–300 °C, is inversely related to the intensity of the D and G peaks. There was more formation of the sp3 at temperatures between 200 °C and 400 °C in the samples as seen by the decrease in the sp²/sp³ ratio from 0.13 to 0.003. XRD revealed the presence of diffraction phases, i.e., ZrC (111), ZrC (400), V₂O₅ (001), Ti (100), Ti (101), and Ti (103) in addition to the TiH₂ and the broadening of peaks for the system annealed at 200 °C and 300 °C due the high H amount, which is consistent with ERDA results.

However, due to the smaller volume of hydrogen molecule compared to that of methane molecule, hydrogen is more likely to permeate through polyethylene pipelines and leaks to the external environment, causing safety issues. To reveal the hydrogen permeation law of hydrogen-blended natural gas in urban gas polyethylene pipelines, the molecular dynamics simulation is used in this study to explore the influence of hydrogen blending ratio, temperature, and pressure on the hydrogen permeation process. In addition, permeation experiments of hydrogen-blended natural gas are conducted on polyethylene pipelines to validate the accuracy of molecular dynamic simulation. Results show that the higher the hydrogen blending ratio and temperature, the stronger the solution capability of hydrogen molecules in polyethylene pipelines. The diffusion ability of hydrogen molecules is positively correlated with the temperature and pressure, and negatively correlated with the hydrogen blending ratio. Overall, the hydrogen permeability coefficient of hydrogen-blended natural gas in polyethylene pipelines increases with the rise of temperature, pressure, and hydrogen blending ratio. The relationship between the hydrogen solubility coefficient, diffusion coefficient, permeability coefficient of hydrogen-blended natural gas and temperature can be described by the Arrhenius law. Besides, the diffusion path of hydrogen molecules reveals that the diffusion of hydrogen-blended natural gas in polyethylene pipelines conforms to the “skipping” principle.
