On July 26, 2024, Professor Rong Cao's team from the Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences, published an article in Angewandte Chemie International Edition. They synthesized a copper-porphyrin-based metal-organic framework catalyst, FICN-8, and explored its CO₂ reduction activity under different electrolyte compositions. 

The study found that FICN-8 primarily produced CO in the absence of a proton source, while the main product gradually shifted to formic acid (HCOOH) when a proton source was added to the electrolyte. This discovery provides new insights into altering CO₂RR product selectivity by tuning the electrolyte composition. 

ReadCrystal Biotechnology collected a total of 11 datasets, from which the four best-quality datasets were selected for combined processing, completing the structure resolution in 4 days.
