Earth Abundant Transition Metals-Based Materials in Chemical Sensors

Melkamu Biyana Regasa, Shibiru Yadeta Ejeta

Sensors are devices that detect and measure specific chemical substances in their environment and are useful in various fields. The recent advancement in materials, synthesis techniques, and signal processing yields highly sensitive and selective chemical sensors. Recently, using earth-abundant transition metals got attention in different research particularly, the first row of transition metals and their compounds, owning to their abundance, low cost, and tunable properties. Pure metals, their oxides as well as their mixture offer additional benefits in the development of chemical sensors, with better merits. Therefore, discussed in this chapter are the general idea and the progress made in utilizing transition metals-based materials for the development of sensors in the context environmental monitoring, biomedical diagnostics, and industrial processes.
