摘要：
The molybdenum-tungsten phosphate (W2-xMoxO3(PO4)(2)) was synthetised and characterised using several techniques. Its catalytic performances was studied in butan-2-ol conversion. The UV-visible investigations showed that the catalyst contains Mo(V) ions. This results was confirmed by the EPR spectra. Additional UN. visible in-situ experimentss, in dynamic conditions revealed that butan-2-ol reduces Mo(VI) into Mo(V) ions. The active sites in the catalytic reaction appearto be built up arround the Mo(VI) ions.
