1 de dic. de 2021 · Abstract. The electrosynthesis of valuable chemicals via carbon dioxide reduction reaction (CO 2 RR) has provided a promising way to address global energy and sustainability problems. However, the selectivity and activity of deep-reduction products (DRPs) still remain as big challenges.
Single-type active sites on the surface gives single-type deep-reduction product. •. Electron-rich Cu 0 -Cu 2 O heterogeneous interfaces promote the formation of ethylene. •. Porous coal matrix modified with PTFE optimizes ethylene current density. Abstract.
Herein, we propose the immobilization of an alkaline ionic liquid on copper for promoting the deep reduction of CO 2. By this strategy, a C 2+ FE of 81.4% can be achieved under a current density of 0.9 A·cm –2 with a half-cell energy conversion efficiency of 47.4% at −0.76 V vs reversible hydrogen electrode (RHE).
1 de mar. de 2024 · A novel machine learning-based approach called deep mechanism reduction (DeePMR) has been developed to address this issue. The current method transforms mechanism reduction into an optimization problem in the combinatorial space of chemical species while mitigating the curse of dimensionality inherent in the high-dimensional space.

A deep reduction and partial oxidation strategy to convert low-cost SiO 2 into mesoporous Si anode with the yield higher than 90% is provided. This strategy has advantage in efficient mesoporous silicon production and in situ formation of several nanometers SiO 2 layer on the surface of silicon particles.
