Perovskite NbxSrTi1-xO3 광 촉매를 이용한 메탄올/물 분해로부터 수소제조
Hydrogen Production from Splitting of Methanol/Water Solution Using Perovskite Structured NbxSrTi1-xO3 Photocatalyts
본 연구는 광 촉매로써 널리 사용되어 온 perovskite 결정인 SrTiO3 골격에 형광능력이 우수한 Nb을 일부 삽입한 NbxSrTi1-xO3를 합성하였고, Nb와 Ti의 몰 비율에 따른 물 분해로부터 수소제조 성능을 비교하고자 하였다. 제조한 SrTiO3 및 NbxSrTi1-xO3 분말에 대한 물성평가는 X-선 회절분석법(XRD), 에너지 분산형 X-선 분광계(EDS), 자외선/가시선 분광계(UV/Vis-spectrometer)를 통해 분석하였다. 메탄올:물(1:1) 광분해 수소제조 실험 결과, SrTiO3 광 촉매보다 Nb이 0.05 mol% 첨가된 Nb0.05SrTi0.95O3 광 촉매에서 촉매활성이 가장 뛰어났으며, 특히 염기성 용액에서 더 많은 양의 수소가 발생하였으며 8시간 반응 후 수소의 발생 누적 량은 4.9 mL였다.
This study focused on the synthesis of NbxSrTi1-xO3 photocatalysts which partially inserted Nb ions with excellent ability of fluorescence into the perovskite structured SrTiO3 frameworks and their photocatalytic hydrogen productions from methanol/water splitting corresponding to the molar ratios of Ti and Nb. The characteristics of the synthesized SrTiO3 and NbxSrTi1-xO3 powders were analyzed by X-ray diffraction (XRD), energy dispersive X-ray spectrometer (EDS), and UV-Visible spectrometer. The hydrogen evolution from methanol/water photo-splitting was
enhanced over Nb0.05SrTi0.95O3 compared to those over SrTiO3 and another NbxSrTi1-xO3; 4.9 mL of hydrogen gases was collected after 8 h when 0.5g of Nb0.05SrTi0.95O3 catalyst was used in pH 10.
