研究方向

目前研究領域為低維材料及其相關體系的電子、聲子、吸附、摻雜等物理化學特性的多尺度模擬,探討其在納米電子學、鋰電池、儲氫、熱電等領域的應用; 金屬及氧化物光催化分解水、CO2光催化還原的機理與性能研究,設計并尋找高效的氧化物光催化材料。

1. 低維材料物理化學性質的多尺度模擬

二維單層結構(石墨烯、磷烯、過渡金屬硫化物等)、過渡金屬氧化物以及復合材料的結構設計及性能研究,探索其在鋰離子電池電極、儲氫材料等領域的應用。目前我們的研究體系包括雜化碳納米結構、石墨烯、磷烯、MoS2、Ti2S3單層二維材料,以及Ti、V、Fe基金屬氧化物的電子結構、離子輸運等性能研究。

2. 光解水及光催化機理與性能研究

金屬氧化物納米結構、異質界面的光催化機理與性能研究,為設計高效的光催化材料提供理論基礎。理論計算研究Bi、Fe基氧化物的本征電子、光學及光電化學性質,通過理性設計調控其光催化分解水性能;過渡金屬硫化物的CO2催化還原機理研究; 液相方法結合原子層沉積方法可控制備高性能光電催化電極。
