| 分子篩硅鋁比與B酸和L酸的多少有關(guān)系嗎?硅鋁比不同,B,L酸怎么變化的 |

| From Figure 6.3 , it is also found that both Lewis and Br ø nsted acidic sites increase with Al contents and the B/L ratio = 0.5 is invariable [12] . This could be explained by aluminum stochastically dispersed in the amorphous silica frameworks. The certain B/L ratio could be obtained in the similar framework.這是趙東元老師Ordered Mesoporous Materials書里面的一句話,應(yīng)該是分子篩硅鋁比與B酸和L酸與比例沒(méi)有關(guān)系,但是分子篩硅鋁比增加B酸和L酸也會(huì)增加。 |
