Abstract: In modern heterogeneous catalysis, it remains highly challenging to create stable, low‐cost, mesoporous 2D photo‐/electro‐catalysts that carry atomically dispersed active sites. In this work, a general shape‐preserving amorphous‐to‐crystalline transformation (ACT) strategy is developed to dope various transition metal (TM) heteroatoms in ZrO2, which enabled the scalable synthesis of TMs/oxide with a mesoporous 2D structure and rich defects. During the ACT process, the amorphous MZrO2 nanoparticles (M = Fe, Ni,… Show more
