a Schematic illustration of fibrous mat with hierarchical pore structures for CH4/H2O diffusion. b CFD simulation showing the diffusion velocities of CH4 gas and electrolyte liquid in reactor (left) and on micropores among interwoven nanofibers (right). The color bar in (b) represents the velocity (m/s). c CFD simulation showing the flow streamlines of CH4 gas and electrolyte liquid in reactor (left) and on micropores among interwoven nanofibers (right). The blue dashed boxes highlight the areas of amplification. d MD simulation results showing the distribution (top) and density (bottom) of CH4 gas/H2O liquid at interface of nanopores inside a single nanofiber. The black dashed boxes highlight the locally concentrated CH4 and H2O on the designed pore interfaces. The color bars in (d) represent the densities of molecules (g/cm3).
