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