Abstract Single-atom catalysts show excellent catalytic performance because of their coordination environments and electronic configurations. However, controllable regulation of single-atom permutations still faces challenges. Herein, we demonstrate that a polarization electric field regulates single atom permutations and forms periodic one-dimensional Au single-atom arrays on ferroelectric Bi 4 Ti 3 O 12 nanosheets. The Au single-atom arrays greatly lower the Gibbs free energy ... compared to that for Au-O=C=O single-site adsorption on Au isolated single atoms. Additionally, ...
