Using Ce(NO3)3·6H2O, Pr(NO3)3·6H2O，and Fe(NO3)3·9H2O as metal sources, and Acid Red 14 (AR14) as carbon source, a Ce-Pr-Fe-O@C photocatalyst was synthesized via a codeposition method. An orthogonal matrix of experiments was used to investigate the effect of the main synthesis parameters on the photocatalytic activity of Ce-Pr-Fe-O@C for the degradation of AR14. The obtained materials were characterized by XRD, SEM, TEM, FT-IR, Raman, XPS techniques, and the results showed that a cubic fluorite structure was formed containing evenly distributed Fe, Pr and C in all samples. The AR14 degradation results showed that the photocatalytic activity of Ce-Pr-Fe-O@C doped with a small amount of Fe, Pr and C is more effective, due to the efficient visible light absorption and the effective separation of photoelectrons and holes resulting from the presence of oxygen vacancies and carbon bonds.

Abstract
Using Ce(NO3)3·6H2O, Pr(NO3)3·6H2O，and Fe(NO3)3·9H2O as metal sources, and Acid Red 14 (AR14) as carbon source, a Ce-Pr-Fe-O@C photocatalyst was synthesized via a codeposition method. An orthogonal matrix of experiments was used to investigate the effect of the main synthesis parameters on the photocatalytic activity of Ce-Pr-Fe-O@C for the degradation of AR14. The obtained materials were characterized by XRD, SEM, TEM, FT-IR, Raman, XPS techniques, and the results showed that a cubic fluorite structure was formed containing evenly distributed Fe, Pr and C in all samples. The AR14 degradation results showed that the photocatalytic activity of Ce-Pr-Fe-O@C doped with a small amount of Fe, Pr and C is more effective, due to the efficient visible light absorption and the effective separation of photoelectrons and holes resulting from the presence of oxygen vacancies and carbon bonds.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
