Quantum Physisorption of Gas in Nanoporous Media: A New Perspective

Although numerous investigations have revealed the gas physisorption characteristics of porous media, essence behavior within nanoscale space is still indistinct. We speculated that a complex molecular system (e.g., CH4 and CO2) exhibits quantum effect due to confinement nanopores. Gas molecules occur in varied orbitals following certain probabilities and, therefore, separate energy levels inside space. Energy level transition from excited state ground triggers physisorption, while non-uniform spatial distribution energy-quantized nanopores dominates behavior. The can be adjusted by temperature, pressure potential field. Based on effect, we developed equation perspective mechanics re-understand basic principles
