Electrosynthesis of value-added chemicals, directly from CO2, could foster achievement of carbon neutral through an alternative electrical approach to the energy-intensive thermochemical industry for carbon utilization. Progress in this area, based on electrogeneration of multicarbon products through CO2 electroreduction, however, lags far behind that for C1 products. Reaction routes are complicated and kinetics are slow with scale up to the high levels required for commercialization, posing significant problems. In this review, we identify and summarize state-of-art progress in multicarbon synthesis with a multiscale perspective and discuss current hurdles to be resolved for multicarbon generation from CO2 reduction including atomistic mechanisms, nanoscale electrocatalysts, microscale electrodes, and macroscale electrolyzers with guidelines for future research. The review ends with a cross-scale perspective that links discrepancies between different approaches with extensions to performance and stability issues that arise from extensions to an industrial environment.

多尺度 CO2 电催化生成 C2+ 产品：反应机制、催化剂设计和设备制造
直接从CO 2电合成增值化学品可以通过能源密集型热化学工业的碳利用替代电力方法促进实现碳中和。然而，该领域的进展基于通过CO 2电还原产生多碳产品，远远落后于C 1产品。反应路线复杂，动力学缓慢，随着规模扩大到商业化所需的高水平，带来了重大问题。在这篇综述中，我们从多尺度角度识别和总结了多碳合成的最新进展，并讨论了当前通过 CO 2 还原生成多碳需要解决的障碍，包括原子机制、纳米级电催化剂、微米级电极和宏观电解槽，并提供了指导以供将来的研究。审查以跨尺度的视角结束，该视角将不同方法之间的差异与工业环境扩展所产生的性能和稳定性问题的扩展联系起来。
