Abstract Wide‐bandgap spinel oxides, such as ZnAl 2 O 4 (ZAO) and ZnCr (ZCO), are traditionally limited by poor electron activation under light irradiation, resulting in suboptimal photocatalytic performance. This study investigates a novel approach to overcoming these limitations leveraging the flexoelectric effect centrosymmetric porous nanoparticles with wrinkled surfaces. The inhomogeneous strain gradients generated mechanical force induce polarization, offering promising pathway enhance activity. ZAO outperforms ZCO due smaller atomic radius of aluminum, allowing greater displacement higher which prolongs electron‐hole recombination. Oxygen vacancies (O V ) further performance, ZAO‐200 (annealed at 200 °C) achieving longest carrier lifetime (4.65 ns) an exceptional hydrogen evolution rate 3737 µmol g −1 h —206% than pristine ZAO—without stimulation. Density functional theory (DFT) calculations confirm lower reaction (HER) energy barrier for (ΔG H = −0.13 eV) compared (1.34 reveal spontaneous water splitting sites without input. A unique butterfly curve validates potential generation from gradients. These findings establish framework eco‐friendly production, demonstrating that polarization engineering can surpass traditional methods sustainability efficiency.
