| 제목 | Synthesis of mesoporous silica SBA-15 in a micro-flow reactor |
| 초록 | In general, mesoporous silica materials have been synthesized in batch reactors by hydrothermal reaction. In the batch system, the reaction time is too long and it is hard to get homogeneous products. On the other hand, the reaction occurs in micrometer-size channels of a micro-flow reactor. For that reason, it can reduce the reaction time by 1/100 due to easy heat/mass transfer. Also, it can produce good products with high quality and the mount of mesoporous silica materials can be prepared in large scale using by multiple parallel flow reactors. In this work, SBA-15 has been made in a flow reactor to overcome disadvantages in the batch reactor. There are many conditions to be monitored such as temperature, flow rate and reaction time. The optimum condition was found in making SBA-15 in a droplet through the flow reactor. The synthesized silica materials were characterized by XRD, BET and TEM. Furthermore, they were compared with the SBA-15 which was prepared in the batch reactor. |
