Integrating nanostructured catalysts with semiconductors is a prevalent strategy for the design of photoelectrochemical (PEC) photocathodes toward CO2 reduction reaction (CO2RR). However, it still challenge to achieve high efficiency and selectivity due incompatible catalyst/semiconductor heterogeneous interface. Here, proposed that engineering oxygen vacancy in TiO2 interlayer plays multifunctional role boosting PEC activity CO2RR on Bi catalyst modified Si photocathode (denoted as Si/dT/Bi). It discovered accelerates carrier transport. These vacancies also promote growth Bi-based sponge-like nanostructures during photoelectro-deposition process. Numerous experimental results combined situ attenuated total reflection surface-enhanced infrared absorption spectroscopy reveal these nano-catalysts Si/dT/Bi provide density active sites adsorption kinetics HCOOH production by accelerating formation key intermediate *OCHO. This provides unique route future advancements technologies.

Abstract Selective photoreduction of carbon dioxide (CO 2 ) into high‐value C products remains a formidable challenge due to the elusive C−C coupling step. Herein, novel concept is first introduced that an amorphous‐crystalline hybrid structure can galvanize previously inert metal atoms, thereby establishing highly active dual sites. This ingenious configuration promotes coupling, paving way for CO products. Taking Bi MoO 6 nanosheets anchored by amorphous FeOOH species as example, X‐ray photoelectron spectroscopy (XPS) spectra and absorption near edge density functional theoretical (DFT) calculations confirm electron transfer from nanosheets. Thus, introduction activates nonoperative sites construction Bi−Mo sites, verified in situ XPS DFT calculations. Gibbs free energy revealed formation barrier hugely lowed 3.41 0.45 eV thanks presence species. Therefore, FeOOHBi are game changer, delivering sole liquid product, acetic acid, with impressive selectivity ≈86.9%. In contrast, lag behind, only capable producing monoxide photoreduction.
