Developing efficient and robust electrode materials for electrochemical sensors is critical for real-time analysis. In this paper, a hierarchical holmium vanadate/phosphorus-doped graphitic carbon nitride (HoVO 4 /P-CN) nanocomposite is synthesized and used as an electrode material for electrochemical detection of hydrogen peroxide (H 2 O 2 ). The HoVO 4 /P-CN nanocomposite exhibits superior electrocatalytic activity at a peak potential of −0.412 V toward H 2 O 2 reduction in alkaline electrolytes while compared with other reported electrocatalysts. The HoVO 4 /P-CN electrochemical platform operated under the optimized conditions shows excellent analytical performance for H 2 O 2 detection with a linear concentration range of 0.009−77.4 μM, a high sensitivity of 0.72 μA μM −1 cm −2 , and a low detection limit of 3.0 nΜ. Furthermore, the HoVO 4 /P-CN-modified electrode exhibits high selectivity, remarkable stability, good repeatability, and satisfactory reproducibility in detecting H 2 O 2 . Its superior performance can be attributed to a large specific surface area, high conductivity, more active surface sites, unique structure, and synergistic action of HoVO 4 and P-CN to benefit enhanced electrochemical activity. The proposed HoVO 4 /P-CN electrochemical platform is effectively applied to ascertain the quantity of H 2 O 2 in food and biological samples. This work outlines a promising and effectual strategy for the sensitive electrochemical detection of H 2 O 2 in real-world samples.

The present work demonstrated a facile exfoliation of g-C3N4 NSs (E-C3N4 NSs) by a sonochemical approach to electrochemical detection of furazolidone (FZD). The structural and morphological characterization of E-C3N4 NSs was systematically verified. The results showed that the as-fabricated E-C3N4 NSs modified electrode exhibited an exceptional electrocatalytic activity for FZD comparing the bare electrode due to the better catalytic activity, electrical conductivity, distinct structure, high specific surface area, and high carrier mobility. Under optimum experimental parameters, the linear detection range of the E-C3N4 NSs-based electrochemical sensor is in a range from 0.002 to 224 μM with a detection limit of 0.0005 μM, which is higher than most reported electrode materials. In addition, the proposed electrode demonstrated strong selectivity and better operational stability toward FZD detection. Interestingly, our proposed electrode was effectively applied to detect FZD in environmental and biological samples with satisfying recovery values. As a result, the E-C3N4 NSs are likely to be used in a variety of electrochemical applications for detecting environmental contaminants.
