Sodium Cation Substitution in Sr₂KTa₅O₁₅ toward Enhancement of Photocatalytic Conversion of CO₂ Using H₂O as an Electron Donor.

ABSTRACT: The K and Sr cations (K⁺ and Sr²⁺) in a Sr₂KTa₅O₁₅ photocatalyst were found to be easily substituted by Na cations (Na⁺) to form Sr _x K _y Na _z Ta₅O₁₅ by a facile one-pot flux method using a mixture of potassium chloride (KCl) and sodium chloride (NaCl). Sr _x K _y Na _z Ta₅O₁₅ fabricated using a mixture of KCl and NaCl with a Ag cocatalyst showed enhanced photocatalytic activity without apparent change in selectivity toward CO for the photocatalytic conversion of CO₂ using H₂O. The present study demonstrates that the flux treatment significantly affected th
