In the present work, a novel method for the green synthesis of CeAlO₃ (CAO) polycrystalline powder through deep eutectic solvents (DES) was carried out by hydrothermal method. The carbon nitride (CN) was synthesized directly by fractional thermal polymerisation process. The combination of CeAlO₃ with CN provides an excellent sensing platform for developing highly sensitive and stable electrocatalyst for non-enzymatic glucose (GLU) oxidation. The structural, morphological and electrochemical analysis of CeAlO₃/CN (CAO/CN) shows the successful synthesis without any impurities. The synergistic effects of pyridinic-N, pyrrolic-N and graphitic-N are highly influencing and playing a prominent role in sensory performances of the prepared CAO/CN nano-electrocatalyst towards GLU sensing. The limit of detection (LOD) at CAO/CN modified glassy carbon electrode (CAO/CN/GCE) was calculated to be 0.86 nM in the linear concentration range of 0.01–1034.5 µM by amperometric method. The anti-interference, reproducibility, repeatability and stability analysis suggest the promising performance of the fabricated electrode towards GLU detection. The real time application of CAO/CN/GCE was evaluated towards GLU sensing in human blood, saliva and sweat, a satisfactory result was obtained. Therefore, the CAO/CN/GCE has a great application prospect as a highly efficient catalyst material for highly sensitive and efficient non-enzymatic glucose sensor.
