AI summary

Provided is an Anderson-type polyoxometalate including titanium (Ti) as a heteroatom in the center of the Anderson-type polyoxometalate. A method for preparing an Anderson-type polyoxometalate includes mixing a titanium precursor and a tungsten precursor to prepare a mixture, sealing the mixture in a container and heating to form a hydrothermal synthetic solution, and cooling the hydrothermal synthetic solution and then adding a solute to form an Anderson-type polyoxometalate.
