利用团簇展开理论结合第一性原理计算,研究了金红石基半导体TiPt7O16的稳定性、电子结构和光吸收。综合计算,我们预测tipt7o16是Pt取代金红石型TiO2(Ti1-xPtxO2(R), x = 0-1)数百种构型中最稳定的结构。更重要的是,精确的HSE06计算表明,tipt7o16是一个潜在的可见光负责光催化剂,带隙为1.70 eV。此外,pt端部(010)和Ti & pt端部(011)表面适合催化整体水分解,因为它们的能带边缘跨越所需的氧化还原电位。
The cluster expansion formalism combined with the accurate first-principles calculations were performed to investigate the stabilities, the electronic structures and the optical absorption of the rutile based semiconductor TiPt7O16. Our comprehensive calculations have predicted that TiPt7O16is the most stable structure among the hundreds of the configurations of Pt substituted rutile TiO2(Ti1-xPtxO2(R), x = 0–1). More importantly, the accurate HSE06 calculations indicate that TiPt7O16is a potential visible-light responsible photocatalyst with the band gap of 1.70 eV. In addition, the Pt-terminated (010) and Ti & Pt-terminated (011) surfaces are suitable for catalyzing the overall water splitting, due to their band edges span over the required redox potential.
