Sluggish charge kinetics and low CO2 affinity seriously inhibit CO2 photoreduction. Herein, the synchronous promotion of charge separation and CO2 affinity of Bi4Ti3O12 is realized by coupling corona poling and surface I‐grafting. Corona poling enhances ferroelectric polarization of Bi4Ti3O12 by ali...
