The Aurivillius phase layered perovskite ferroelectric material Sr2Bi4Ti5O18 (SBTO) exhibits spontaneous polarization and piezoelectric properties, which confer significant potential for piezo-photocatalysis. Its ability to enhance electron–hole separation while providing excellent fatigue resistance positions it as a promising candidate in this field. Defects were introduced improve the structural photoelectrochemical properties of SBTO. SBTO nanocrystals, featuring mixed structure hierarchically ordered mesoporous microflowers nanosheets, successfully synthesized via hydrothermal method. sample at lower temperature displayed optimal oxygen vacancy concentration exhibited superior piezoelectric-photo synergistic degradation activity organic pollutants. Additionally, corona increases macroscopic photocatalyst, promoting photogenerated carriers. Finite element simulations confirmed that single flower-like generates higher compared sheet-like morphology. In conclusion, integrating self-assembled hierarchical design, polarization, defect engineering forms an effective strategy achieving high-performance SBTO-based piezo-photocatalysts.

Abstract The “shuttle effect” and sluggish conversion reaction kinetics of polysulfides seriously hinder the practical application Li−S batteries. In this study, nano‐sized LaMnO 3 (N‐LMO) with typical perovskite structure combined highly‐conductive carbon black (SP) was introduced on commercial separator to fabricate a functional surface modification. It is found that polar N‐LMO abundant active sites offers strong chemisorption towards soluble meanwhile accelerates their redox conversion, conductive SP contributes extra spots reactivate trapped sulfur species. Consequently, synergistic effect adsorption‐catalysis‐conduction built by cooperative N‐LMO/SP modification greatly enhances as well suppresses polysulfide shuttling not at expense weakening Li‐ion transport, which endows cell high initial discharge capacity 1143.6 mAh g −1 0.2 C decay rate only 0.072 % per cycle 1 over 500 cycles.

MXenes are promising cathodes for Li-CO2 batteries owing to their high electrical conductivity and efficient CO2 activation function. However, the effects of adsorption electronic structures MXene on full life cycle have been rarely investigated. Here, we employ a coregulation approach enhance adsorption-decomposition lithium carbonate (Li2CO3) by introducing Zn Cl surface groups onto Ti3C2 (Zn-Ti3C2Cl2) catalyst. The incorporation enhances Li2CO3 catalyst surface, resulting in formation small-sized uniform Li2CO3. Additionally, introduction shifts d-band centers titanium promotes evolution reaction (CO2ER) activity, thereby facilitating decomposition discharge products. As result, battery based Zn-Ti3C2Cl2 exhibits an ultralow overpotential (0.72 V) at 200 mA g-1 stable cycling up 1500 h. This work validates efficacy promoting reversibility adjusting process.

In this article, an effective redox regulation strategy of Li–S batteries is illustrated by introducing a unique petal‐like LaMnO 3 nanosheet (LMO‐NS) into the sulfur cathode. It found that LMO‐NS with abundant active sites offers strong chemical affinity toward species, which play key roles in immobilizing produced polysulfides during charge/discharge operation and then accelerating their conversion. Consequently, reaction kinetics remarkably boosted polysulfide shuttle greatly alleviated owing to adsorption‐catalysis effects LMO‐NS, endows composite cathode increased reversible capacity improved cycle rate capability.
