Extra-Large-Pore Zeolites with Two-Dimensional Chann

转载Science, Vol 304, Issue 5673, 990-992 , 14 May 2004 Porosity measurements. The specific surface area was determined from nitrogen adsorption isotherms at 77 K on a Micromeretics ASAP 2010 porosimeter (Fig. S2) using the BET method (S4). The pore diameter of IM-12 (Fig. S3) was determined by the Horvath-Kawazoe method (S5) applied on the adsorption branch of the isotherm. 研究级超高性能全自动气体吸附仪系统
