In-depth understanding of the real-time behaviors of active sites during electrocatalysis is essential for the advancement of sustainable energy conversion. Recently, the concept of dynamic active sites has been recognized as a potent approach for creating self-adaptive electrocatalysts that can address a variety of electrocatalytic reactions, outperforming traditional electrocatalysts with static active sites.

1 Introduction Electrocatalytic water splitting driven by intermittent renewable electricity is an attractive approach to producing clean hydrogen fuel, which involves the anodic oxygen evolution reaction (OER) and the cathodic hydrogen evolution reaction (HER) of an electrolysis cell.[1, 2] While noble-metal-based catalysts (e.g., IrO2, RuO2, and Pt) hold the benchmark performance toward both OER and HER, their large-scale application is hindered by natural scarcity, high cost, and limited...

The introduction of functional ligands, which is beneficial for the assembly of perovskite nanocrystals (PNCs), has opened up new avenues in fabrication of highly efficient optoelectronic and photovoltaic devices. In this work, self-assembled organic-inorganic hybrid lead bromide perovskite cubic supercrystals have been synthesized via a wet chemistry approach using trifunctional L-cysteine as capping ligands.
