N-Graphene Sheet Stacks/Cu Electrocatalyst for CO2 Reduction to Ethylene

Autor: Peteris Lesnicenoks, Ainars Knoks, Sergei Piskunov, Laimonis Jekabsons, Janis Kleperis

Publikováno v: Electrochem, Vol 3, Iss 2, Pp 229-238 (2022)

Renewable energy resources (wind, solar) are unpredictable, so it is wise to store the electricity they generate in an energy carrier X. Various PtX (power to useful energy-intensive raw material such as hydrogen, synthetic natural gas, fuel) applica
