Electrochemical Methods and Materials for Transition Metal-Based Electrocatalysts in Alkaline and Acidic Media

OpenAlex · İngilizce

The increasing population and economic growth of developed and developing countries have increased global energy demand, and so increasing pursuits have been carried out to search for renewable energy sources. Hydrogen plays a key role as a green energy carrier for the future owing to its low volumetric and high gravimetric energy content, zero carbon emission, and earth-abundance. However, the high costs are a significant obstacle to the commercialization of these systems. Generally, high-cost noble metals are used as catalysts in hydrogen production. Therefore, inexpensive catalyst research is one of the main pathways for reducing system costs of hydrogen production. Transition metal-based are among the more accessible materials because of their abundance worldwide. This chapter highlights the use of transition metal-based catalysts like Ni, Cu, Co, Fe, and other transition metals as an alternative to precious metal catalysts for acidic and alkaline media. It discusses the performance of elemental and composite forms of transition metal-based alkaline and acidic electrochemical systems.
