摘要(Abstract)：

随着经济高速发展，光催化技术由于其不仅可以制备出清洁氢能源，同时还可以降解污染物，已成为清洁能源制备和环境污染处理领域内潜在的重要技术之一。作为光催化技术的核心材料TiO_2,由于其具有良好的耐光腐蚀性和催化活性已成为最具潜力的光催化剂，但传统的TiO_2光催化剂存在可见光利用率低以及光生电子空穴对复合速度快等缺点，使其在光催化领域的应用受到限制。为了解决上述问题，表面改性和掺杂的方式是提高TiO_2光催化活性最有效的途径。目前，二维(2D)材料由于其独特的结构和性能，已成为TiO_2光催化潜在的理想载体材料，同时还可以实现其表面改性，将二者进行复合发挥其协同作用，可以显著改善TiO_2的光催化性能。因此，本文以二维材料和TiO_2光催化材料为中心，重点介绍了二维材料/TiO_2复合材料的制备方法，并详细地介绍二维材料/TiO_2复合材料的光催化机理，旨在为新型TiO_2光催化剂的制备提供理论指导。
