Principles and mechanisms of photocatalysis
When photocatalyst (such as CdS, ZnS, TiO 2, ZnO, SnO 2, CeO 2, etc.) absorbs suitable light, it produces electron hole pairs (e-/h +) in the CB and VB respectively.The electrons in the VB of semiconductors become excited when irradiated by light. The excess energy of this excited electron promoted the electron to the CB of …

Photothermal catalysis: From principles to applications
However, there are still several problems which limit the large-scale application of photocatalysis (e.g., low utilization of solar energy [6, 7]). It is noteworthy that most photocatalysts utilize more energy from the UV band and do not respond well to the visible band, which has a much higher energy share [ 8 ].
Principles and applications of photothermal catalysis
The difference between various photothermal catalysts is the specific destination (or final forms of energy) of all the absorbed solar energy, originating from …
