“…At present, in addition to the process of achieving pure products, there is continuous research on the direct high-value utilization of V and W obtained after separation and purification for the preparation of photocatalytic materials like Zn 3 (VO 4 ) 2 / ZnWO 4 112 and for the synthetic assembly of VO 2 battery materials, 113 and others. This is conducive to reducing process losses and improving the efficiency of V and W utilization.…”

Selective catalytic reduction denitration technology, abbreviated as SCR, is essential for the removal of nitrogen oxide from the flue gas of coal-fired power stations and has been widely used. Due to the strong demand for energy and the requirements for environmental protection, a large amount of SCR catalyst waste is produced. The spent SCR catalyst contains high-grade valuable metals, and proper disposal or treatment of the SCR catalyst can protect the environment and realize resource recycling. This review focuses on the two main routes of regeneration and recycling of spent vanadium−titanium SCR catalysts that are currently most widely commercially used and summarizes in detail the technologies of recycling, high-efficiency recycling, and recycling of valuable components of spent vanadium−titanium SCR catalysts. This review also discusses in depth the future development direction of recycling spent vanadium−titanium SCR catalysts. It provides a reference for promoting recycling, which is crucial for resource recovery and green and lowcarbon development.
