Web)O systems, the pore size distributions of the HTlcs were narrower and the pore diameters were smaller. The BJH pore diameters and pore volumes confirmed that O was an Cu(Fe) non-porous material, which explained its low surface area. The BJH pore diameters and pore volumes also illustrated that most of the prepared MO were non-porous materials. WebWhen considering pore size, a set of standards approved by IUPAC has defined pore size ranges based on different size widths. Pores with an internal width of less than 2 nm are referred to as micropores, those with an internal width between 2 nm and 50 nm as mesopores, and those larger than 50 nm are called macropores (See Figures 2 and 3).
