- Abstract
To more efficiently develop the single-atom catalysis, it is essential to deeply characterize the single-atom catalysis structure and study their catalytic mechanisms at the molecular and atomic scale. Herein, this paper reviews the advanced techniques for charactering the structure of single-atom combustion catalysis, including synchrotron-radiation based X-ray absorption spectroscopy (XAS) and spherical aberration-collected transmission electron microscopy. Meanwhile, synchrotron-tradiation based operando and in-situ techniques are introduced, including XAS, Fourier transform infrared (EQIR) and synchrotron vacuum ultraviolet radiation photoionization mass spectrometry (SVUV-PIMS), which could play vital roles in unravelling the reaction mechanisms. These advanced structural characterizations to investigate the existence of single-atom catalysis and their catalytic mechanisms would significantly provide a new vision for the design and synthesis of single-atom combustion catalysis. Furthermore, current challenges and future research directions of these characterization techniques in single-atom combustion catalysis are presented. 38 References are included.
