Abstract: The Cd atom is doped into the Au 19 Cd 3 (3,5‐DMBT) 18 − (referred to Au 19 Cd 3 , 3,5‐DMBT = 3,5‐Dimethylbenzenethiol) nanocluster, obtaining obtained a new cluster Au 18 Cd 4 (3,5‐DMBT)18 (referred to Au 18 Cd 4 )Au 18 Cd 4 . Significantly, the kinetic processes of Au 19 Cd 3 through Au 18 Cd 4 are studied using traditional time‐dependent UV–vis spectra and ESI‐MS. However, the kinetic studies are limited to qualitative analysis due to the inability to harmonize their mass spectral patterns. In this case, time‐dependent thin‐layer chromatography plates (TD‐TLC) are introduced into this kinetic study. Benefiting from the inclusion of TD‐TLC, the conversion behavior of Au 19 Cd 3 to Au 18 Cd 4 is confirmed to be gradual and equiproportional. In combination with the crystal structure of Au 18 Cd 4 , the doping behavior of the fourth Cd atom is traced. Finally, the significance of the conversion of Au 19 Cd 3 to Au 18 Cd 4 clusters is illustrated with the help of photocatalysis, in which the further doping of cadmium atoms leads to a continuous increase in the catalytic activity.
