Abstract High carrier recombination causes a huge waste of photogenic charge, which severely restrains the photocatalytic efficiency. Creating polarization electric field by polar materials proves effective to promote charge separation, while developing efficient strategy is challenging and related micromechanism remains obscure. Here, overall achieved in Bi 2 MoO 6 single crystal photocatalyst lateral growth nanoplate along {010} facets. Gradual elongation equatorial Mo─O bonds octahedral layer occurs, length apical basically unchanged, thus allowing large asymmetric distortion octahedron for producing microscopic polarization. Meanwhile, nanoplates enables accumulation distorted units, further increasing intensities. The inside‐out significantly promotes separation migration photogenerated carriers. finely polarized exhibit an exceptional selective oxidation rate benzyl alcohol (BA) benzaldehyde (BAD) under visible light irradiation (Conversion (Con.) ≈100% within 30 min, Selectivity (Sel.) ≥95%), over 70.7 times that original nanosheets, on condition comparable O adsorption capability.
