Periodic trends in the hydrodenitrogenation activity of carbon-supported transition metal sulfide catalysts

Transition Metal Sulfide Catalysts for Petroleum Upgrading – Hydrodesulfurization Reactions

Supported Homogeneous Catalysts TRANSITION METAL COMPLEXES WITH POLYMERIC LIGANDS

Almost all industrial catalysts are heterogeneous, the reaction taking place on a solid surface. During the past decade homogeneous catalysts, soluble in the liquidphase reactant, have received a great deal of attention, although they have so far found only limited industrial use, chiefly because of the di$culty of their separation from the reaction products. More recently an intermediate type,...

Sintering of Supported Metal Catalysts

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Strong interactions in supported-metal catalysts.

Many commercially important catalysts consist of small metal particles dispersed on inorganic oxide surfaces. Although in most cases there is no significant interaction between the metal and the support, strong bonding can be demonstrated in a recently discovered class of supported-metal catalysts. These cases typically involve group VIII metals dispersed on transition metal oxides whose surfac...
