Transition metal doped Sb@SnO2 nanoparticles (TM-Sb@SnO2) were synthesized to enhance a catalytic effect of SnO2 which can be used for detecting Cys. As abnormal level of L-cysteine (Cys) can make some obstacles in metabolism, the detection of Cys is important in the field of diagnostics. We assess some information about size distributions, shapes of particles, and formation of single-phase by using surface analysis technique, such as transmission electron microscopy (TEM), X-ray diffraction (XRD), scanning transmission X-ray microscopy (STXM), and high-resolution photoemission spectroscopy (HRPES). Then TM-Sb@SnO2 were evaluated catalytic effects by measuring photocatalytic oxidation and electrochemical oxidation of Cys. Through the spectral analysis, we found that the Cr- and Mn-doped SnO2 nanoparticles exhibit enhanced catalytic activities, which according to the various surface analyses were due to the effect of the sizes of the particles and electronegativity differences between the dopant metal and SnO2.
