Abstract
The development of efficient, cost–effective, and stable bifunctional electrocatalysts for overall water
splitting is of paramount importance in alkaline mediums. In this study, we report the synthesis of the
CdTiO3 nanoparticles using the simple low–temperature sol–gel approach. CdTiO3 as an electrodic
material exhibits enhanced catalytic performance, advantageous reaction kinetics, and remarkable
longevity for both the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). The
nanostructured CdTiO3 demonstrates the overpotentials of 270 and 320 mV to attain a current density
of 10 mA cm−2 for OER and HER in 1.0 M KOH electrolyte, respectively. It reveals the low Tafel slope
values of 63 and 79 mV dec−1 for OER and HER, respectively. This work proposes a sustainable strategy
for developing enhanced bifunctional electrocatalysts for hydrogen fuel production via overall water
splitting, which has the potential to replace noble metals in a wide range of renewable energy systems.
