A.; Zimmerman, Steven C.; Gewirth, Andrew A. published an article in 2021. The article was titled 《Electrochemical CO2-to-ethylene conversion on polyamine-incorporated Cu electrodes》, and you may find the article in Nature Catalysis.Recommanded Product: 51857-17-1 The information in the text is summarized as follows:
Electrochem. conversion of CO2 into value-added chems. holds promise to enable the transition to carbon neutrality. Enhancing selectivity for a specific hydrocarbon product is challenging, however, due to numerous possible reaction pathways of CO2 electroreduction Here we present a Cu-polyamine hybrid catalyst, developed through co-electroplating, that significantly increases the selectivity for ethylene production The Faradaic efficiency for ethylene production is 87% ± 3% at -0.47 V vs. reversible hydrogen electrode, with full-cell energetic efficiency reaching 50% ± 2%. Raman measurements indicate that the polyamine entrained on the Cu electrode results in higher surface pH, higher CO content and higher stabilization of intermediates compared with entrainment of additives containing little or no amine functionality. More broadly, this work shows that polymer incorporation can alter surface reactivity and lead to enhanced product selectivity at high current densities. In the experiment, the researchers used many compounds, for example, N-Boc-1,6-Diaminohexane(cas: 51857-17-1Recommanded Product: 51857-17-1)
N-Boc-1,6-Diaminohexane(cas: 51857-17-1) is a compound useful in organic synthesis used in the preparation of mixed self-assembled monolayers (SAMs) that resist adsorption of proteins using the reaction of amines with a SAM that presents interchain carboxylic anhydride groupsRecommanded Product: 51857-17-1
