由于宽带隙和大的激子结合能,氧化锌(ZnO)目前在各个领域备受关注,并且可以以各种形式制备,包括纳米棒,纳米线,纳米花,等等。单一掺杂剂产生的ZnO的可靠性不稳定,这反过来又促进了共掺杂技术的发展。共掺杂是一种非常有前途的技术,可以有效地调制光学,电气,磁性,和ZnO的光催化性能,以及形成各种结构的能力。在本文中,综述了共掺杂ZnO纳米材料的重要进展,以及采用不同方法制备共掺杂ZnO纳米材料,包括热液,溶剂热,溶胶-凝胶,和声学化学。此外,共掺杂ZnO纳米材料在光催化领域的广泛应用,太阳能电池,气体传感器,讨论了生物医学。最后,还阐明了共掺杂ZnO纳米材料领域的挑战和未来前景。
Due to a wide band gap and large exciton binding energy, zinc oxide (
ZnO) is currently receiving much attention in various areas, and can be prepared in various forms including nanorods, nanowires, nanoflowers, and so on. The reliability of
ZnO produced by a single dopant is unstable, which in turn promotes the development of co-doping techniques. Co-doping is a very promising technique to effectively modulate the optical, electrical, magnetic, and photocatalytic properties of
ZnO, as well as the ability to form various structures. In this paper, the important advances in co-doped ZnO nanomaterials are summarized, as well as the preparation of co-doped
ZnO nanomaterials by using different methods, including hydrothermal, solvothermal, sol-gel, and acoustic chemistry. In addition, the wide range of applications of co-doped
ZnO nanomaterials in photocatalysis, solar cells, gas sensors, and biomedicine are discussed. Finally, the challenges and future prospects in the field of co-doped ZnO nanomaterials are also elucidated.
