The interactions of polyoxovanadates (POVs) with proteins have increasingly attracted interest in recent years due to their potential biomedical applications. This is especially the case because of their redox and catalytic properties, which make them interesting for developing artificial metalloenzymes. Organic-inorganic hybrid hexavanadates in pa...
A trial coagulation of the water of the Volchikhinsky reservoir with aluminum sulfate and aluminum polyoxychloride was carried out in order to compare the effectiveness of reducing the content of total organic carbon (TOC). It is noted that aluminum sulfate more effectively reduces the concentration of TOC without loss of quality in other indicator...
The widespread use of selective catalytic reduction (SCR) catalysts has resulted in a large accumulation of spent SCR catalysts. These spent catalysts present a significant risk of environmental hazards and potential for resource recovery. This paper presents a feasible process, which works using atmospheric pressure leaching, of tungsten and titan...

Iron seriously affects the quality of TiO2 support recovered from spent selective catalytic reduction (SCR) catalyst. In this paper, the iron removal and TiO2 support recovery from spent SCR catalyst were studied. The experiment results suggested that iron exists on the surface and bulk structure of a spent SCR catalyst. The iron deposited on the s...

Currently, deep eutectic solvents (DESs), as an exclusive class of ionic liquid analogs, are extensively employed in various fields. Herein, vanadium phosphorus oxide (VPO) catalysts assisted by copper-based deep eutectic solvent (Cu-DES) as an electronic promoter and structure directing agent were ingeniously synthesized and exploited in the selec...

A sustainable method for Ti, Al, and Mg recovery from titanium-bearing blast furnace slag (TBBFS) coupled with CO2 sequestration by leaching residue is proposed. The results show that the original mineral phase of the TBBFS could be destroyed by ammonium sulfate roasting, in which the valuable metals were converted to sulfates. Subsequently, Ti, Al...
