수열 합성법과 마이크로파 가열법으로 제조한 TS-1의 촉매 성능 평가를 과산화수소수를 이용한 페놀 수산화 반응에서 수행하였는데 아세톤과 메탄올 및 물의 세 가지 용매를 사용하여 각 용매에서의 페놀 전환율과 생성물의 선택도 변화를 관찰하였다. 수열 합성법으로 제조한 TS-1과 마이크로파 가열법으로 합성한 TS-1의 XRD, EDS, SEM, BET 흡착/탈착 시험을 통해 촉매의 특성을 비교·분석하였고 마이크로파 가열법으로 합성한 TS-1이 수열 합성으로 제조한 TS-1과 상이한 페놀 전환율과 생성물의 선택도를 보이는 이유에 대해서 설명하였다.

Catalytic activity such as conversion and selectivity on the phenol hydroxylation over TS-1 prepared by hydrothermal method and microwave heating method, respectively, was compared and discussed for understanding the dependence of solvent such as water, methanol, acetone, respectively, during phenol hydroxylation, with hydrogen peroxide. Basic physical properties such as XRD, EDS, SEM and N2 adsorption/desorption were determined and compared. The relationship between catalytic activity and physical properties of TS-1 was explained.
