Developing efficient and robust electrode materials for electrochemical sensors is critical real-time analysis. In this paper, a hierarchical holmium vanadate/phosphorus-doped graphitic carbon nitride (HoVO4/P-CN) nanocomposite synthesized used as an material detection of hydrogen peroxide (H2O2). The HoVO4/P-CN exhibits superior electrocatalytic activity at peak potential −0.412 V toward H2O2 reduction in alkaline electrolytes while compared with other reported electrocatalysts. platform operated under the optimized conditions shows excellent analytical performance linear concentration range 0.009–77.4 μM, high sensitivity 0.72 μA μM–1 cm–2, low limit 3.0 nΜ. Furthermore, HoVO4/P-CN-modified selectivity, remarkable stability, good repeatability, satisfactory reproducibility detecting H2O2. Its can be attributed to large specific surface area, conductivity, more active sites, unique structure, synergistic action HoVO4 P-CN benefit enhanced activity. proposed effectively applied ascertain quantity food biological samples. This work outlines promising effectual strategy sensitive real-world
