Description
Fuping Pan and colleagues show how support curvature flips oxygen reaction paths in a 2026 catalysis study. Iron phthalocyanine usually drives full oxygen reduction, rarely the two-electron route to peroxide. Placing the molecule on curved carbon pores changed that choice.
Molecules in concave pores favored peroxide with selectivity above 80 percent in the reported tests. Molecules on convex supports favored the full four-electron route instead. Infrared readings during operation and theory traced the split to shifted orbital overlap at the iron site. Curvature thus acts as a dial for steering electrochemistry without changing the catalyst itself.
