1. 1. Modelling Local pH Values and Ion Distributions near Gold Nanoparticles

   University essay from Umeå universitet/Kemiska institutionen

   Author : Lisa Tete; [2021]
   Keywords : ;

   Abstract : Corrosion is the sum of processes by which an element, commonly a metal, wears away, deteriorates [1]–[3]. One of these processes uses the principle of electrochemistry as a basis, being the transfer of electrons between one chemical reaction and the element that undergoes corrosion [4], [5]. READ MORE

   Abstract : Abstract The work attempts to find out the effects of current parameters on particle codeposition and microhardness of composite coatings. Also, it uses pulse reverse current in increasing nanoparticle content and microhardness. READ MORE

4. 3. Synthesis of Ruthenium-based Water Oxidation Catalysts and Mechanistic Study

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : YOSHIDA MOTOKI; [2015]
   Keywords : Ruthenium Complex; Water Oxidation Catalyst; Electrochemistry; Oxygen Evolution; Pourbaix Diagram;

   Abstract : Two series of new mononuclear ruthenium complexes with hydrophobic or hydrophilic ligands [Ru(bda)L2] and [Ru(pdc)L3] (H2bda = 2,2'-bipyridine-6,6'-dicarboxylic acid; H2pdc = 2,6-pyridinedicarboxylic acid; L = pyridyl ligands) were synthesized and their electrochemical properties and catalytic activity toward water oxidation were examined. It was revealed that the hydrophobic ligands introduced to [Ru(bda)L2 ] improved the catalytic performance, ahnost twofold TON and TOF values were achieved compared to the [Ru(bda)] catalyst with hydrophilic ligands.
