Nanocrystalline rutile TiO2 powders were modified with small amounts of CuOx and FeOx clusters by impregnation and drying. The modified rutile samples exhibited drastically enhanced photocatalytic degradation of 4-chlorophenol under UV+vis (λ>320nm) irradiation. The reaction rates were increased by the factor of 7 and 4 for the optimized TiO2(R)-CuOx and TiO2(R)-FeOx samples containing 0.12wt.%...
The heterogeneous catalytic transformations of bi- and polyfunctional alcohols to the corresponding linear and branched (but not cyclic) amines are reviewed. The aminating components are mainly ammonia, but also primary and secondary amines. The typical catalysts can be divided into two main groups: supported metal and multimetallic hydrogenation catalysts (e.g., Ni, Co, Cu and Ru on alumina or...
