1. IntroductionClick to copy section linkSection link copied!Separation processes are essential across a broad range of industrial applications but are often highly energy intensive. Distillation as the most dominant separation process takes up 10–15% of the world’s energy consumption by some estimates. (1) Gas separations using polymer-based membranes are a promising alternative that significantly reduces the required energy and capital costs.

As the demand for clean energy increases, environmentally friendlier methods for separation, capture, and use of hydrocarbons and alkane gases in particular have become important to the petrochemical industry. (1−6) These separations are traditionally carried out using energy-intensive distillation, and adsorption processes in porous materials such as zeolites are attractive as potential alternative methods for separation and purification.

Compared with the traditional heat-driven separation technologies like distillation, evaporation, and drying, diffusion-based separations have the potential to be more energy efficient and therefore lower emissions and pollution. (1−4) In this approach, mixtures of molecules are separated by porous materials based on their geometric or chemical properties in a diffusion process. Finding materials that have the “right” pores is critical for diffusion-based separation to succeed.

Next, the magnetic coupling characteristics of adjacent doped h-BN are studied. Figures 4(a)–4(c) show the spin charge density of Si–O3-doped h-BN under short range, medium range, and long range magnetic coupling, with corresponding central impurity distances of 7.79, 9.19, and 10.32 Å, respectively. First, among the three coupling forms, the medium range coupling configuration exhibits the lowest ground state energy.
