摘要:A method for synthesis of iron-based nanoparticles is disclosed. The method includes mixing, an ascorbic acid solution with a citric acid solution to form a mixture. The mixture includes 20 mL of 0.1 M ascorbic acid solution and 20 mL of 1 M citric acid solution. The method also includes adding, a plurality of iron salts nitrate nonahydrate solution to ascorbic acid and citric acid mixture then stirring, the mixture using a magnetic stirrer and adding 8 ml of 0.005 M of Sodium Hexachloroplatinate Hexahydrate solution to the mixture. Further, the method includes adding a Sodium tetra hydrido borate to the mixture resulting in a black coloured solution along with effervescence and holding, the mixture undisturbed after the effervescence stops to obtain a green coloured solution. Furthermore, the method includes decanting, the green coloured solution, stirring at room temperature and obtaining, a plurality of iron nanoparticles.

摘要:Aspects of the present disclosure are directed to electrochemical approaches for synthesis of platinum-iridium alloys with selected platinum-iridium ratio content and subsequently predetermined mechanical properties and electrochemical impedance properties. Such can provide a simple and cost-effective process for preparing these electrodes, as compared to conventional thin film processing techniques. A three-electrode electrochemical electrodeposition system is described including an electrochemical cell with a working electrode on which the electrodeposited film is deposited, a counter electrode to complete the electrochemical circuit and a reference electrode to measure and control surface potential. Mixed layers of platinum atoms and iridium atoms can be deposited from electrolyte solution onto the working electrode surface to create an electrically conductive surface with material properties related to the composition of the as-deposited film. The mechanical properties and electrochemical properties of the film can be tuned by adjusting the electrodeposition parameters.
