“…Arsenic-based compounds possess different binding abilities and biological activities. The arsenic-based compounds are often used for medical purposes, wood preservation, agricultural sectors, and so on. , The catalytic properties and binding ability of Cu compounds are quite interesting because of their variable oxidation states like Cu(0), Cu(I), Cu(II), and Cu(III). − Cu-based compounds show different geometrical aspects, Jahn–Teller distortion, and magnetic behavior. Till date, few Cu-based ternary oxide catalysts, such as CuBi 2 O 4 , CuSb 2 O 4 , CuAl 2 O 4 , and CuMn 2 O 4 , have been reported for effective dye degradation, organic transformation, water splitting, and other catalytic applications. − Cu-based spinel or ternary oxides are very popular.…”
