The experimental results show that ammonia molecule is adsorbed preferentially on the B acid sites.实验结果还表明氨分子在B酸中心上优先被吸附。
The results showed that both L and B acid sites exist on SO- 2- 4/TiO 2 photocatalys t while only L acid sites on TiO 2 photocatalyst.结果表明 ,TiO2 光催化剂的表面只有L酸中心 ,而SO2 -4 /TiO2 光催化剂表面既有L酸中心也有B酸中心。
As demonstrated in the 1H MAS NMR experiment, the number of B acid sites per unit cell was 1 12 on the Mo/HZSM-5 catalyst prepared using unmodified zeolite as support, but it was only 0 88 on the Mo catalyst supported on modified HZSM-5 zeolite.未经改性的Mo/HZSM 5催化剂表面 ;平均每个晶胞中有 1 12个B酸位 ;而改性的Mo/HZSM 5催化剂表面 ;平均每个晶胞中仅有 0 88个B酸位 .
The IR spectrum rcsearch shows, there were no hydroxyl groups and no B acid sites on the AIPO4-5. But there were two hydroxyl groups at 3666cm-1 and 3620 cm-1on the SnAPO_5, B acid sites were present.从TPR谱所得结果表明;Sn已进入骨架且不易被还原成零价的Sn.;AlPO_的IR谱上无羟基峰出现;其表明没有B酸位存在;而SnAPO_出现了3666cm~和3620cm~二个羟基峰;表明有B酸位存在
