Synthesis and analysis of adaptive Pd-integrated perovskite catalysts for effective NO_x-reduction under lean conditions

, 2009
The literature reports a series of precious metal integrated perovskite based catalysts revealing intelligent properties [1]. Lanthanum based perovskites are among these catalysts that are able to stabilize precious metal ions such as Pd, Pt, Rh, Ru, etc.

Extremely Long Electron Lifetime in Spontaneously Passivated Polycrystalline Perovskite Layers via Illumination‐Assisted Trap Filling

Advanced Functional Materials, EarlyView.
ABSTRACT Perovskite solar cells (PSCs) are promising next‐generation photovoltaics. The high performance of PSCs is attributed to the long carrier lifetimes of perovskite photoabsorbers. However, the carrier lifetimes of polycrystalline perovskite layers, which serve as the photoabsorbers in practical PSCs, have remained limited to several tens of ...
