Doping is an effective way to improve the activity of photocatalysts. The effect of doping on the magnetic properties of some photocatalysts that are easily recycled was studied using the local spin density approximation (LSDA)+U method on typical divalent metal oxide semiconductors CuO, NiO, Ni-doped CuO, and Cu-doped NiO. It is found that the influence of Ni doping on the spatial structure of CuO and that of Cu doping on the spatial structure of NiO are negligible because of the similar radii of Ni2+ and Cu2+. The valence band and conduction ...

光催化分解水制H_2和光催化还原CO_2是解决能源危机和全球变暖的有效途径.但是,由于粉末光催化剂存在回收效率低的问题,因而光催化成本很高.而磁性光催化剂便于回收和重复利用,因此人们把目光转向具有磁性的非光催化剂材料,试图通过改性使得磁性材料具有合适的水分解或者还原CO_2的氧化还原电位.同时,对具有光催化活性但是没有磁性的材料进行磁化改性可以得到新型的磁性光催化剂.本文通过对本身具有磁性的NiO材料进行Cu掺杂能带调整,使调整后的NiO具有合适的氧化还原电位;对本身具有良好光催化氧化还原电位的CuO材料进行Ni掺杂磁化调整,使磁化后的CuO既有良好的氧化还原电位又有磁性.最终两种材...
