Lithium acetylide
WebElectrochemical oxidation of lithium acetylide in aprotic media affords carbon films containing a high fraction of sp-type C bonds; the growth conditions and the photoelectrochemical behaviour of these films were investigated. Web15 mei 2024 · The lithium metal reference electrodes provide a reference potential of 0 V, so the measured voltage between anode and RE is identical with the anode potential. Therefore, Li/Cu RE has been widely utilized as an external observation method of internal reaction processes [ 33, 41, 42, 43 ].
