In this study, the
preparation of Sm
2
CuZrO
6
double perovskites
was carried out through the utilization of a
sol–gel technique. The Sm
2
CuZrO
6
displayed
notable conductivity, impressive electrocatalytic activity, and rapid
electron transfer. The monitoring of risperidone (RIS) in tablet samples
is greatly influenced by these properties. Various techniques for
structural and morphological characterization were employed to confirm
the formation of Sm
2
CuZrO
6
. The electrochemical
properties of Sm
2
CuZrO
6
were assessed through
utilization of cyclic voltammetry (CV), electrochemical impedance
spectroscopy (EIS), and linear sweep voltammetry (LSV). Interestingly,
the Sm
2
CuZrO
6
exhibited a remarkable wide linear
range of 50–500 nM, along with a detection limit of 10.62 nM.
Notably, it demonstrated a sensitivity of 0.4038 μA μM
–1
cm
–2
. The constructed sensor demonstrated
noteworthy selectivity, stability, and repeatability. To assess the
practicality of RIS, its performance was monitored in the tablet sample,
resulting in satisfactory recoveries.
