Yucheng Ou, Bing Wang, Nana Xu, Quzhi Song, more

Advanced Materials > 36 > 30 > n/a - n/a

Prolonging energetic hot electrons lifetimes and surface activity in the reactive site can overcome the slow kinetics and unfavorable thermodynamics of photo‐activated gas sensors. However, bulk and surface recombination limit the simultaneous optimization of both kinetics and thermodynamics. Here tandem electric fields are deployed at (111)/(100)Au‐CeO₂ to ensure a sufficient driving force for carrier...
