“…This suggests that under hydrophobic contact conditions, the rougher the surface, the more favorable it may be for nucleation if it possesses a variety of different types of roughness. In this case, the theoretical results can explain the experimental phenomenon that hydrophobic nanoparticles promote hydrate formation 53–56 …”

As a new form of energy with substantial potential, natural gas hydrate will play a crucial strategic role in the future due to its vast reserves and broad industrial application prospects. To better comprehend the nucleation and growth mechanism of clathrate hydrate, an enhanced thermodynamic model was proposed based on the wall roughness model and nucleation theory. In general, we discovered that the nucleation of hydrate on a smooth wall surface conforms to the conclusion of classical nucleation theory. However, curvature and surface roughness are frequently characterized by hydrophilicity's inhibition of hydrate and hydrophobicity's enhancement.The specific situation is more complex and requires specific analysis and discussion.Nonetheless, this also explains the uneven distribution of hydrate nucleation induction time. Our research reveals a fundamental method for designing or manipulating the heterogeneous nucleation of hydrates. We foresee promising applications in hydrate-related technologies based on the fractal structure of the substrate's surface.

“…In this case, the theoretical results can explain the experimental phenomenon that hydrophobic nanoparticles promote hydrate formation. [53][54][55][56] Figure 7D illustrates the case of x = 10, meaning that the radius of the nucleus is 10 times the radius of curvature of the rough surface.…”
