Titanium-embedded layered double hydroxides as highly photocatalysts for water oxidation under visible light

摘要

The present invention relates to a method for preparing a layered double hydroxide photocatalyst in which titanium is oxidized in the visible region, and more specifically, adding a metal precursor and a titanium metal precursor to an aqueous solution of urea and dissolving the solution. Obtaining; Reacting the solution; And a method for preparing a layered double hydroxide photocatalyst having titanium intercalated in the visible light region, the method comprising: cooling and then reacting the reactant with a centrifuge, followed by washing and drying.
