The reaction of Ni(CH3COO)2’6H2O, 4-hydroxycinnamic acid (Hhca) and 4,4’-bipyri- dine (bipy) ligand in water-solution afforded a mononuclear complex [Ni(H2O)4
The mixed oxides La_ 1-x Ce_xFe_ 1-y-n Co_yRu_nO_3 were prepared by sol-gel method and used as catalysts for NO direct decomposition. The catalysts were charact
