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　mu　mol　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.
