Structural features of electrodeposited copper electrodes for CO2 conversion
Machado, A. S. Reis; Fernandes, T. R. C.; Pardal, T.; Rangel, C. M.Direct electrochemical reduction of CO2 is a process that could contribute to the reduction of the emission of greenhouse gases by using CO2 as a raw material for fuel production. This paper focuses on voltammetric studies of functionalized electrodes for the electrochemical conversion of CO2 and reports on its use as a tool for electrode screening and optimization. Nickel substrates modified with copper and ru...
Conversion of carbon dioxide into fuel by electrochemical reduction in aqueous ...
Pardal, T.; Fernandes, T. R. C.; Machado, A. S. Reis; Rangel, C. M.he mission of Omnidea, a Portuguese SME is to perform leading edge R&D in innovative energy concepts. In collaboration with Research Institutes Omnidea is developing a technology based upon a regenerative energy storage cycle. In this cycle the recharge system converts CO2 into hydrocarbons using a renewable source of power. The discharge system produces electrical energy when hydrocarbons and oxygen from the r...
Modified electrodes for electrochemical reduction of carbon dioxide
Machado, A. S. Reis; Fernandes, T. R. C.; Pardal, T.; Rangel, C. M.The efforts to constrain greenhouse gas emissions and concerns over security of fossil fuels have led to increased attention for renewable energy for the past decade. Renewable energy is one of the key solutions to the actual energy challenges. Omnidea in collaboration with Research Institutes is developing a technology based upon a regenerative energy storage cycle that could be a contribution to a low-carbon ...
Scale-up of a system for hydrocarbon production by electrochemical reduction of...
Fernandes, T. R. C.; Machado, A. S. Reis; Condeço, J.; Rangel, C. M.; Pardal, T.This work addresses the scaling up of a system for electrochemical reduction of CO2 to produce hydrocarbons that can be used as fuel for a regenerative energy storage cycle. Challenges involved in such a task are mentioned. Scalingup results of a system based on electrodes of high surface area with modified copper deposits are described. Current densities around 100 mA/cm2 were obtained. This corresponds to the...
