With rising CO2 emissions caused by the massive consumption of fossil fuels, it is highly desirable to develop strategies that adopt renewable energy to convert CO2 into value-added chemical feedstocks. Over the past decades, photocatalytic reduction of CO2 using light energy has attracted considerable attention. However, the advanced photocatalysis techniques cannot exert their action where light is unavailable. Here, a method for CO2 reduction on basis of vibration-driven piezoelectricity to yield a piezo-electrocatalysis effect which requires mechanical vibration rather than light, is proposed. Under mild vibration and sacrificial agent-free conditions, the piezoelectric BaTiO3 catalyst provides a suitable piezo-potential to overcome the redox potential of CO2 and convert it into CO with a maximum yield of 63.3 µmol g−1, achieving a reactivity comparable to those of photocatalysts. The piezo-electrocatalytic CO2 reduction reaction adds a new avenue in addition to the existing photocatalytic techniques by expanding the scope of energy utilization to promote carbon neutrality.

振动驱动的压电催化二氧化碳减排
随着化石燃料的大量消耗导致 CO 2排放量增加，非常需要制定采用可再生能源将 CO 2转化为增值化学原料的战略。在过去的几十年中，利用光能光催化还原CO 2引起了相当大的关注。然而，先进的光催化技术无法在没有光的情况下发挥作用。在这里，提出了一种基于振动驱动压电的 CO 2还原方法，以产生需要机械振动而不是光的压电电催化效应。在温和振动和无牺牲剂条件下，压电 BaTiO 3催化剂提供了合适的压电电位来克服CO 2的氧化还原电位并将其转化为CO，最大产率为63.3 µmol g -1，实现了与光催化剂相当的反应性。压电催化CO 2还原反应通过扩大能量利用范围促进碳中和，在现有光催化技术的基础上增加了一条新途径。
