Preparation of W0.4Mo0.6O3 from Secondary Resources by a Simple Heat-Treatment Process and Discussion of Its Superior Selective Adsorption Properties

Recovery of W–Mo Alloy Scrap and the Photochromic Properties of WO3/MoO3 Composite Products

“…27−29 However, direct extraction of the metal without separation and preparation into functional materials is common in waste battery materials. 30,31 Although we have successfully used a heat treatment method to obtain W 0.4 Mo 0.6 O 3 from W− Mo alloy scrap, 32 it does not have superb photochromic properties. Hence, the development of an efficient method for the rapid extraction of W and Mo, leading to the production of photochromic materials, holds significant practical value.…”

“…Another approach to separate W and Mo involves the introduction of certain elements , or substances to widen the gap between them . Nevertheless, regardless of the method employed, the process of separating and extracting W and Mo into isolated metals tends to be time-consuming and resource-intensive in terms of labor and materials. − However, direct extraction of the metal without separation and preparation into functional materials is common in waste battery materials. , Although we have successfully used a heat treatment method to obtain W 0.4 Mo 0.6 O 3 from W–Mo alloy scrap, it does not have superb photochromic properties.
