Auric oxide is primarily used in specialized catalytic applications, particularly in oxidation reactions where high selectivity is required. It serves as a catalyst in the conversion of carbon monoxide to carbon dioxide at low temperatures, making it valuable in gas purification systems and sensors. Due to its stability under oxidative conditions, it is also employed in the manufacturing of certain electronic components and conductive coatings. Additionally, auric oxide finds use in research settings for developing gold-based nanomaterials with potential applications in sensors and medical diagnostics. Its unique electronic properties make it suitable for experimental studies in semiconductor devices and electrochromic systems.
