Abstract
Converting CO 2 into sustainable fuels or useful carbon-derived substances offers an effective strategy for tackling the energy crisis and combating global warming. Photo-/electrocatalytic CO 2 reduction provides a simple, energy-efficient, and environmentally friendly route compared to existing technologies. Ferroelectric materials, characterized by their unique spontaneous and switchable polarization, have emerged as promising candidate catalysts due to their controllable surface physical and chemical properties. This review commences by summarizing the mechanism underlying ferroelectric polarization-modulated photo-/electrocatalytic CO 2 reduction. We then highlight the recent key advancements in CO 2 reduction utilizing ferroelectric materials, along with their performance promotion strategies. Finally, we explore the obstacles and future perspectives in this field. This review will provide useful guidance for systematic design and advancement of effective photo-/electrocatalysts based on ferroelectric materials.
