摘要:
Similar ordered microporous carbons were synthesized by a dry chemical vapor deposition (CVD) method. Acetylene CVD over powdered zeolite Y at 600°C was performed for 4 h and then a portion of the zeolite/carbon composite powder was subjected to further CVD using acetylene or propylene at 700°C for 1h. The SEM image of zeolite Y exhibited crystal habits in each particle, indicating that each particle corresponded to a single crystal. The long-range regularity inherited from the original zeolite crystal and the uniformity of micropore size in the present carbons are higher than those in the carbon prepared using the (furfuryl alcohol) FA impregnation process.
