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.

The coupling between the host (MIL-88B) and guest (cobalt porphyrin, CoPP) produces high-density bimetallic atomic active sites.

As the different types of ions could change the properties of vanadium oxides in various ways, the review starts with a comprehensive overview of pre-intercalated vanadium oxide cathode with different types of molecules and ions, such as metal ions, water molecules, and non-metallic cations, along with their functional principles and resulting performance. Furthermore, the pre-intercalated vanadium cathodes reported so far are summarized, comparing their interlayer space, capacity, cycling rate, and capacity retention after long cycling. A discussion of the relationship between the interspace and the performance is provided. The widest interspaces could result in the decay of the cycling stability. Based on the data, the optimal interspace is likely to be around 12 Å, indicating that precise control of the interspace is a useful method. However, more consideration is required regarding the other impacts of pre-intercalated ions on vanadium oxide.

Herein, a self-recognition separator based on a Bi-based metal–organic framework (GF@CAU-17) is developed for ion management to achieve highly reversible Zn anodes. The GF@CAU-17 has self-recognition behavior to customize selective Zn²⁺ channels, effectively repelling SO₄^2– and H₂O, but facilitating Zn²⁺ conduction. The inherent properties of CAU-17 result in the repulsion of SO₄^2– ions while disrupting the hydrogen bond network among free H₂O molecules, restraining side reactions and by-products. Simultaneously, the zincophilic characteristic of CAU-17 expedites the desolvation of [Zn(H₂O)₆]²⁺, leading to a self-expedited Zn²⁺ ion pumping effect that dynamically produces a steady and homogeneous Zn²⁺ ion flux, and thereby alleviates concentration polarization. Consequently, a symmetric cell based on the GF@CAU-17 separator can achieve a long lifespan of 4450 h.
