1. An electrode for carbon dioxide reduction and ethylene production, the electrode comprising a basic electrocatalyst comprising:
catalyst particles including copper hydroxide (Cu(OH)2); and
basic particles including a basic compound, wherein the basic particles have a nanoparticle form of 10 nm or less, a secondary particle form in which the nanoparticles of 10 nm or less form an aggregate, or a mixed form thereof;
wherein the catalyst particles and the basic particles are supported on a microporous substrate,
wherein the catalyst particles include little or no elemental copper as observed in an X-ray diffraction pattern of the catalyst particles, and
wherein the basic compound includes at least one of KOH, NaOH, LiOH, RbOH, CsOH, FrOH, Be(OH)2, Ca(OH)2, Mg(OH)2, Sr(OH)2, Ba(OH)2, or Ra(OH)2.
