Abstract

The integration of advanced electrocatalysts has revolutionized modern sensing
technologies, enabling unique capabilities in environmental monitoring, health�care diagnostics, and industrial process control. This review examines the current
state and future directions of electrocatalyst materials and their applications in
sensing platforms. It covers the remarkable progress in developing novel nano�material architectures, from metal-free catalysts to sophisticated hybrid systems,
highlighting how strategic materials selection and design enhance key perfor�mance metrics including sensitivity, selectivity, and long-term stability. The
review also covers a comprehensive discussion of metal-based, metal-free, and
hybrid electrocatalysts with a focused analysis of their roles in enhancing sensor
performance. Our discussion includes innovative approaches in materials engi�neering, particularly the emergence of two-dimensional materials like MXenes,
and metal–organic frameworks, which have demonstrated exceptional potential
for simultaneous multi-analyte detection. The review also provides insights into
advanced voltammetric methods used in research for precise electrochemical
sensing. Also, the review concludes by addressing challenges in scaling and sus�tainability, while exploring promising opportunities of combining artifcial intel�ligence and smart sensor development.
