Greetings,
I am doing some research on the synthesis of SBA-15. The XRD patterns for a SBA-15 are typical for a 2D hexagonal mesostructure (p6mm). Now what I don't fully understand is what the physical meaning ,when it is mentioned that the d100 spacing is 6 nm, is supposed to be . Is it the distance between two pore centers or the pore diameter?
Best regards
