Carbon dioxide (CO2) concentrations in the atmosphere have been attributed to the acceleration of global warming. Electrochemical CO2 to liquid fuels potentially addresses future energy demands and is highly desirable for the establishment of a sustainable civilization. Various studies indicate that using electrochemistry to turn CO2 into hydrocarbon molecules. Additionally, it reduces the effectiveness of renewable energy utilization to fight climate change and use lead to a long-term and useful technology. The crystalline structure of the porous metal oxide has been functioning as a high-efficiency catalyst, proving that the low current density and absence of selectivity of the transition metal catalyst render it ineffectual. Strategies based on heterogeneous nanostructures material surfaces enable tunable adsorption aspects of various processes and intermediates to tremendous potential, significantly increasing catalytic performance while improving ethanol product selectivity. In order to consider structures for the various issues that can affect processes, chemistry, chemical, mechanical, and electrical engineering, environmental science, economics, and government policy must coordinate. Due to several advantages of structural rigidity for catalyst performance, load bearing capacity increases electrolysis. They are concerned about improving the current densities of high-selective products and the long-term structural stability of the catalyst with most of the essential ethanol products. Hydrogen evolution and reactions involving new pathways and an appropriate level of detail are more productive. Electrocatalysis requires extensive understanding of reaction mechanisms, including both theoretical and experimental features. Additional technological improvements under these prospective studies will require complementary solutions capable of mitigating cost requirements higher than the sum of the parts and a feedback loop between multiple system design initiatives. This symposium will highlight the role of nanomaterials and energy-environmental application research.
