In this study, we developed a poly-fluorination strategy for surface treatment in perovskite solar cells, which enabled a high and durable interfacial phase purity after surface passivation. The locked surface dimensionality of perovskite was achieved through robust interaction between the poly-fluorinated ammoniums and the perovskite surface, along with the steric hindrance imparted by fluorine atoms, reducing its reactivity and penetration capabilities. The high hydrophobicity of the poly-fluorinated surface also aids in moisture resistance of the perovskite layer.

Herein, we for the first time delve into the mechanism of tailoring the solvation sheath and desolvation processes at the electrode/electrolyte interfaces to enhance the structural stabilities in the deep discharge states. In this work, the TiO₂ front interfaces are induced on electrochemically active but unstable TiSe₂ host materials to construct unique TiO₂/TiSe₂–C heterointerfaces. According to X-ray absorption near edge structure (XANES), differential electrochemical mass spectrometry (DEMS), and electrochemical quartz crystal microbalance (EQCM), the intercalated species are transformed from [Zn(H₂O)₆]²⁺ to [Zn(H₂O)₂]²⁺ due to the built-in electric fields (BEFs) effects, further accelerating the ion transfer kinetics. Furthermore, owing to the absence of high-energy desolvation solvents released from desolvation processes, hydrogen evolution reaction (HER) energy barriers, Ti–Se bond strength, and structural stabilities are significantly improved, and the initial CE and HER overpotentials of the TiO₂/TiSe₂–C heterointerfaces increased from 13.76% to 84.7%, and from 1.04 to 1.30 V, respectively, and the H₂ precipitation current density even at −1.3 V decreased by 73.2%.

However, the photocatalytic efficiency and selectivity are still unsatisfactory due to the limited availability of active sites on the current photocatalysts. To resolve this issue, the design of oxygen vacancies (OVs) in metal–oxide semiconductors is an effective option. Herein, in situ deposition of TiO₂ onto SiO₂ nanospheres to construct a SiO₂@TiO₂ core–shell structure was performed to modulate the oxygen vacancy concentrations. Meanwhile, charge redistribution led to the formation of abundant OV-regulated Ti–Ti (Ti–OV–Ti) dual sites. It is revealed that Ti–OV–Ti dual sites served as the key active site for capturing the photogenerated electrons during light-driven CO₂ reduction reaction (CO₂RR). Such electron-rich active sites enabled efficient CO₂ adsorption and activation, thus lowering the energy barrier associated with the rate-determining step. More importantly, the formation of a highly stable *CHO intermediate at Ti–OV–Ti dual sites energetically favored the reaction pathway towards the production of CH₄ rather than CO, thereby facilitating the selective product of CH₄. As a result, SiO₂@TiO₂-50 with an optimized oxygen vacancy concentration of 9.0% showed a remarkable selectivity (90.32%) for CH₄ production with a rate of 13.21 μmol g⁻¹ h⁻¹, which is 17.38-fold higher than that of pristine TiO₂.
