Preparation of WO3/MoO3-x composites from W–Mo alloy scrap and it's adsorption-photocatalytic properties
A straightforward hydrothermal method was employed to fabricate WO3/MoO3 composites, with the addition of ascorbic acid (Vc) for modification, resulting in WO3/MoO3 composites with oxygen defects (WO3/MoO3-x). WO3/MoO3-x exhibits exceptional adsorption-photocatalytic properties, demonstrating strong adsorption capability for dyes achieved through hydrogen bonding and electrostatic interactions. For all products, adsorption rates for methylene blue (MB) exceeded 95 % when reaching adsorption equilibrium. Moreover, an increase in molybdenum (Mo) content endows the samples with enhanced adsorption capacity for methyl orange (MO) and improved photocatalytic performance. Dynamic fitting of the samples revealed that when the W/Mo molar ratios is 2:8, the product W2Mo8-Vc, exhibits the highest photocatalytic activity. After 3 h of illumination, W2Mo8-Vc achieves a remarkable photocatalytic efficiency of 98 % for dyes. This research not only successfully recycles W–Mo alloy scrap but also yields WO3/MoO3-x composites with adsorption-photocatalytic properties, offering a novel approach for the recycling of W–Mo secondary resource.
