A research team has identified critical factors influencing the electrochemical reduction of carbon dioxide (CO2RR) using tin monoxide (SnO)-based electrocatalysts.
A research team has identified critical factors influencing the electrochemical reduction of carbon dioxide (CO2RR) using tin monoxide (SnO)-based electrocatalysts. Their study provides a deeper understanding of how structural changes in SnO affect the production of valuable chemicals such as formic acid (HCOOH) and carbon monoxide (CO), both of which play significant roles in fuel production and industrial applications.
The study was published in the journal ACS Catalysis on February 6, 2025.
While Sn-based materials are widely recognized for their cost-effectiveness and non-toxic nature in CO2RR, existing studies have primarily focused on tin dioxide (SnO2), which predominantly produces HCOOH. Through large-scale data mining of experimental CO₂RR literature, the research team identified a significant trend: SnO-based catalysts demonstrate the ability to generate both HCOOH and CO in comparable amounts. However, despite this potential, the structure-activity relationships of SnO in CO₂RR remain underexplored.
