Gallium Modulated Tin Oxide for Continuous Production of Formic Acid via Durable Acidic CO2 Electroreduction

Prof. Biaobiao Zhang’s group at the Center of Artificial Photosynthesis for Solar Fuels at Westlake University has published a research paper in the Science Advances. The paper is titled “Gallium Modulated Tin Oxide for Continuous Production of Formic Acid via Durable Acidic CO₂ Electroreduction.”

The research reported a facile method to prepare a Ga-doped SnO_x catalyst for acidic CO₂ electroreduction and reveal the lattice oxygen anchoring effect of Ga establishes a stable framework, protecting the Sn^δ+ from the heavy self-reduction process and achieving the durable acidic CO₂ electroreduction to pure HCOOH solution for more than 4000 h.

Assistant researcher Bingquan Jia and Ph.D. student Zhe Chen from Westlake University are first authors. Prof. Biaobiao Zhang and Pro. Tao Wang from the Center of Artificial Photosynthesis for Solar Fuel at Westlake University are the corresponding authors.
