· JVASP-19675· MoAs2

MoAs₂ is a molybdenum arsenide intermetallic compound belonging to the transition metal pnictide family. While primarily of academic and research interest rather than established commercial production, molybdenum arsenides are investigated for their potential as catalysts, thermoelectric materials, and semiconductors due to their layered crystal structure and mixed-valence electronic properties. The material represents an emerging class of materials in catalysis research, particularly for hydrogen evolution reactions and other electrochemical applications, though industrial-scale adoption remains limited.
