| 中文摘要: |
| 钛酸锶（SrTiO3）光催化剂是一种钙钛矿型三元氧化物，具有较强的氧化还原能力、良好的物理化学稳定性及环境友好等特点，在光催化各领域得到了广泛应用，如制氢/降解/光电催化等.SrTiO3对太阳光的利用率较低，且其本征光催化活性受光生载流子分离效率等因素限制，阻碍了实际应用.针对以上问题，围绕国内外SrTiO3改性研究的现状进行综述，主要从掺杂、负载、复合改性等方面进行陈述.最后，对高效稳定SrTiO3光催化剂的未来发展趋势进行展望. |
| 英文摘要: |
| Strontium titanate (SrTiO3) photocatalyst is a kind of perovskite ternary oxide, which has strong redox ability, excellent physical and chemical stability and environmental friendliness. SrTiO3 is broadly utilized in photocatalysis domain, such as water splitting, photodegradation, photoelectrochemical cell etc. The practical application of intrinsic SrTiO3 is limited by narrow light response range, low separation efficiency of photogenerated carriers. To the above issue, this review will canter on the modification studies of SrTiO3, including doping, loading, composite. Finally, the future development trend of highly efficient and stable SrTiO3 photocatalyst is prospected. |
