The search for sustainable energy solutions has led to extensive research on new electrocatalysts that can convert electrical energy into chemical energy and back. Tantalum nitrides stand out as an intriguing class of materials, showcasing exceptional properties such as high melting points, remarkable mechanical strength, and notable resistance to corrosion. These attributes position tantalum nitrides (Ta-N) and allied phases (Ta-N-X) as compelling candidates for diverse applications, notably in electrocatalysis. While traditionally studied for their photocatalytic and photoelectrocatalytic properties, this review ventures into largely uncharted territory, illuminating the untapped potential of tantalum nitrides as electrocatalysts. Electrocatalysis assumes a pivotal role in numerous renewable energy technologies, including fuel cells and water electrolysis, which demand materials adept at catalyzing reactions efficiently. The distinctive characteristics of Ta-N phases, particularly their electrical conductivity, chemical stability, and expansive surface area, mark them as promising contenders in this arena. This comprehensive review article aims to unveil the electrocatalytic prowess of Ta-N phases, examining their catalytic performance concerning the Hydrogen Evolution Reaction (HER), Oxygen Evolution Reaction (OER), and Oxygen Reduction Reaction (ORR). Delving into recent advancements over the past five years, the article scrutinizes strategies employed to counter surface ...
