Emerging environmental pollutants pose increasing risks to ecosystems and human health, creating a demand for analytical tools capable of sensitive and selective detection in complex environmental matrices. In this context, electrochemical sensors based on mixed‐oxide nanostructured materials have attracted growing interest due to their excellent electrocatalytic activity, tunable surface properties, acid‐basic Lewis and Bronsted properties, and suitability for on‐site monitoring. This review examines recent advances in mixed‐oxide‐based electrochemical sensors for the detection of environmental pollutants, including pharmaceuticals, dyes, Anti‐inflammatory and antipyretic drugs, pesticides, endocrine‐disrupting compounds, and heavy metals. The review also explores how material composition, synergistic interactions between metal centers, and nanostructure design affect the electroanalytical performance of modified electrodes. Current challenges related to reproducibility, stability, and selectivity are also discussed, along with perspectives for the rational design and practical application of these sensors in environmental monitoring.
