Nano violet tungsten oxide (usually referring to nano-sized violet tungsten oxide with the chemical formula of WO₂.₇₂ or W₁₈O₄₉) is an important tungsten oxide with a wide range of applications. Here are the main characteristics of nano violet tungsten oxide:

Researchers from Beijing University of Technology have developed an innovative process for efficiently recovering tungsten (W) and molybdenum (Mo) from waste fluid catalytic cracking (FCC) catalysts. The proposed method, termed "oxidative roasting-alkali roasting-wet ball milling leaching," offers a dual benefit: it significantly enhances the extraction efficiency of these valuable metals while minimizing waste liquid and gas emissions, achieving a balance between resource recovery and environmental sustainability.
