Rutile and anatase TiO 2 nano particles with Ni doping were synthesized by mechanical alloying, and were characterized by XRD, TEM, UV-DRS and photoluminescence (PL) spectra. The relationships between crystal type and photocatalytic activity as well as the mechanisms of transition metal doping on TiO 2 lattice were studied. The results showed that the rutile type TiO 2 with...
A series of CuO–CeO 2 catalysts with Cu content in the range of 5–50 at.% (the atomic percent of Cu/(Cu+Ce)) were prepared by co-precipitation method. The catalysts were tested for CO oxidation and selective CO oxidation with CO 2 , H 2 O and excess H 2 . The catalysts were highly active in the CO oxidation and also active and remarkably selective in the selective oxidation...
