Microfluidics‐Assisted Synthesis of Hierarchical Cu 2 O Nanocrystal as C 2 ‐Selective CO 2 Reduction Electrocatalyst (Small Methods 5/2022)

Back Cover In article number 2200074, Yun Jeong Hwang, Heejin Kim, Kwangyeol Lee, and co-workers use a microfluidic system to synthesize hierarchical Cu2O nanocrystals with multiple steps (h-Cu2O ONSs) by kinetics-manipulated crystal growth. Due to the surface reconstruction of h-Cu2O ONSs under electrochemical CO2 reduction, h-Cu2O ONS catalysts exhibit high selectivity for ethylene production.
