Niobium and tantalum were incorporated into the faujasite aluminosilicate structure in one-pot synthesis and also by post-synthesis method, i.e. solid-state ion exchange. One-pot synthesized zeolites exhibit Nb and Ta incorporated into the zeolite skeleton as evidenced by different methods. The efficiency of metal incorporation examined by XPS measurements was found to be higher for tantalum than for niobium.
