Ruthenium complexes, reactions adsorption

The effect of the polymer-coating of the electrode appears to be not only the immobilisation of the ruthenium complex but also adsorption of the oxalate ions on the polymer layer. Possible practical applications of such polymer-coated electrodes are in the electrochemical analysis of trace compounds by concentration in the film [24, 25] and electroanalysis of slow reactions, e.g. mediation of enzyme redox processes [22]. 

The inhibition effect of promoters on the methanation. R is commonly believed that for fused iron catalyst, AI2O3 increases iron surface area (structural effect), while K2O donates electrons to iron atom, and increases electron density and enhances the activity of ammonia synthesis reaction (electronic effect). For the supported ruthenium catalysts, the effect of promoters on performances becomes more complex due to the existence of support. ARhough there are a lot of studies on the role of promoter for ammonia synthesis reaction, the chemical state, the distribution and the mechanism are still unclear. The role of promoters include covering chemisorption s site, donating electron to active metal, direct interacting with the adsorption intermediate and electrostatic field and so For supported...
