The aim of the present paper is to study the speciation and the role of different active site types (copper species and Brønsted acid sites) in the direct synthesis of furan from furfural catalyzed by copper-exchanged FAU31 zeolite. Four series of s

A novel design of combustion catalysts is proposed, in which clay/TiO2/MnAl-mixed oxide composites are formed by intermixing exfoliated organo-montmorillonite with oxide precursors (hydrotalcite-like in the case of Mn-Al oxide) obtained by an inverse

Hydrotalcite-like precursors containing Cu and Mn have been prepared by adding Al as an element promoting the layered structure formation. Materials with (Cu + Mn)/Al equal 3 or 8, and Cu/Mn equal 0.5 or 1, have been investigated and characterized wi
