Abstract
Provided is a preparing method of linear carbonate compounds, including performing a coupling reaction of carbon dioxide in the presence of a titanium dioxide complex. The titanium dioxide complex includes an anatase phase and a rutile phase, a reduced titanium dioxide which is formed by selectively reducing any one of the anatase phase and the rutile phase, and a metallic oxide bound to the reduced titanium dioxide.

A preparing method of linear carbonate compounds, comprising:
- performing a coupling reaction of carbon dioxide in the presence of a titanium dioxide complex,
- wherein the titanium dioxide complex has an anatase phase and a rutile phase, a reduced titanium dioxide which is formed by selectively reducing any one of the anatase phase and the rutile phase, and a metallic oxide bound to the reduced titanium dioxide,
- wherein the titanium dioxide complex is doped with a metal,
- wherein the titanium dioxide complex serves as a photocatalyst so that carbon dioxide is reduced to carbon monoxide, and
- wherein the metallic oxide includes a member selected from the group consisting of W, Mo, Cr, Re, Ir, Ta, Hf, Fe, Ni, Cu, Zn, Mn, Y, V, Bi, Sr, Ca, Nb, K, Na, Li, and combinations thereof.
A photocatalyst for preparing linear carbonate compounds, comprising:
