Abstract : Carbon dioxide reduction by mechanical energy-induced is a promising strategy for reducing greenhouse gas emissions and harvesting simultaneously mechanical energy. Unfortunately, is still an open challenge the low efficiency energy conversion. Here, multiple-pulse, flow-type triboelectric plasma with dual functions of harvesting driving chemical reactions and mechanical energy is introduced to carbon dioxide efficiently reduce. CO selectivity of 92.4% is achieved under normal temperature and pressure, and the CO and O2 evolution rates reach 12.4 and 6.7 μmol h−1, respectively. The maximum energy conversion efficiencies of 2.3% from mechanical to chemical energy and 31.9% from electrical to chemical energy are reached. The low average electron energy in triboelectric plasma and vibrational excitation dissociation of carbon dioxide with low barrier is revealed by optical emission spectra and plasma simulations, which enable the high energy conversion efficiency. The triboelectric plasma approach reduction reported here provides a promising strategy for efficient utilization of dispersed and renewable mechanical energy.
