The thesis has found a new method to increase the pore size of mesoporous carbon by filling the liquid glass into the pore of the template (silica SBA-15) before impregnating the carbon presource to limit the penetration of carbon sealed the pore system of SBA-15. Stability of mesoporous carbon is increases due to silicon are partially retained in materials. This technique opens the way of synthesis of mesoporous carbon as an adsorbent with a desired pore size and stability. | Summary of chemistry doctoral thesis: Study on synthesis, characteristics, and adsorption properties of toxic organic substances in the water environment of mesoporous carbon materials MINISTRY OF EDUCATION VIETNAM ACADEMY OF AND TRAINING SCIENCE AND TECHNOLOGY GRADUATE UNIVERSITY OF SCIENCE AND TECHNOLOGY- ---------------------------- NGUYEN THI HONG HOA STUDY ON SYNTHESIS, CHARACTERISTICS AND ADSORPTION PROPERTIES OF TOXIC ORGANIC SUBSTANCES IN THE WATER ENVIRONMENT OF MESOPOROUS CARBON MATERIALS Major: Theoretical Chemistry and Physical Chemistry Code : SUMMARY OF CHEMISTRY DOCTORAL THESIS Ha Noi – 2019 The work was completed at: Graduate Universty of Science and Technology - Vietnam Academy of Science and Technology.

The necessity of the thesis Mesoporous carbon materials have an ordered structure, uniform pore size. They often were synthesized by two methods: soft-templating and hard-templating. With the soft-templating method, materials have been prepared via self-assembly by using soft-templating (surfactant). The obtained materials have less orderly structure. The pore size of the material is difficult to control and the template is difficult to remove. With the hard-templating method, MCM-48, SBA-15, etc. are used as the templates. The materials have highly order structure, uniform and easily controlled pore size. Therefore, hard-templating method is used more widely. However, the pore size .
