Overview
Chromium copper oxide丨CAS 12018-10-9 is an inorganic compound composed of copper (Cu), chromium (Cr), and oxygen (O). It commonly adopts a delafossite-type crystal structure and is known for its p-type semiconducting properties. The material appears as a dark, often black or brown, fine powder and is valued for its electrical, catalytic, and optical properties.
Applications
Transparent Conductive Oxides (TCOs)
Used in thin-film photovoltaics and electronic displays as a p-type TCO due to its optical transparency in the visible range and good electrical conductivity.
Applied in solar cells, especially in tandem with n-type semiconductors, to form p-n junctions in transparent electronics.
Catalysis
Serves as a catalyst or catalyst support in hydrogenation, oxidation, and dehydrogenation reactions.
Active in heterogeneous catalysis, particularly for converting alcohols and other organic intermediates.
Gas Sensors
Incorporated in semiconductor gas sensors to detect volatile organic compounds (VOCs) and gases like CO or H₂ due to changes in conductivity upon gas adsorption.
Battery and Supercapacitor Materials
Investigated as a component in electrode materials for lithium-ion batteries and supercapacitors due to its redox-active metal centers and stability.
Thermoelectric and Magnetic Materials
Studied for use in thermoelectric devices and magnetoresistive components thanks to its unique electron transport properties.
Pigment Industry
Occasionally used in ceramics and glass for coloration due to its stable and intense hue.
Benefits
P-Type Conductivity
Unlike many TCOs, which are n-type, chromium copper oxide provides p-type conductivity, enabling new combinations in electronic and optoelectronic device design.
Environmental Stability
Exhibits excellent thermal and chemical stability, making it suitable for high-temperature or harsh environmental applications.
Low Toxicity and Heavy Metal-Free Alternative
Considered a less toxic alternative to some heavy-metal-based semiconductors, aligning with safer material standards in electronics and coatings.
High Catalytic Activity
Offers high surface area and stability under reaction conditions, increasing its utility in catalytic applications.
Versatile Functional Material
Useful across a wide range of advanced technologies, including clean energy, sensing, and environmental applications.
Conclusion
Chromium copper oxide丨CAS 12018-10-9 is a multifunctional inorganic material with promising applications in semiconductors, catalysis, and energy devices. Its p-type conductivity, thermal resilience, and catalytic activity make it an attractive choice for researchers and industries aiming to develop efficient and stable materials for next-generation technologies.
