· Mo5 As4

Mo5As4 is a molybdenum arsenide compound belonging to the transition metal pnictide family, a class of materials studied for their electronic and catalytic properties. This is primarily a research compound rather than an established commercial material, investigated for potential applications in electrocatalysis, thermoelectric devices, and high-temperature electronics where molybdenum-based intermetallics can offer improved performance over conventional semiconductors. Engineers exploring Mo5As4 are typically motivated by its potential for hydrogen evolution catalysis and energy conversion applications in emerging clean-energy systems.
