Piezocatalysis has increasingly gained prominence due to its enormous potential for addressing energy shortages and environmental pollution issues. Nonetheless, the low piezocatalytic activity of state‐of‐the‐art materials seriously inhibits the practical applications of piezocatalysis. Here, it is proposed to greatly enhance the piezocatalytic activity for a perovskite ferroelectric, i.e., Sm‐doped...
Lead‐free dielectric ceramics with excellent energy‐storage performance are crucial to the development of the next‐generation advanced pulse power capacitors. However, low energy‐storage density limits the evolution of capacitors toward lightweight, miniaturization, and integration. Here, an effective strategy of constructing highly dynamic polarization heterogeneous nanoregions is proposed in lead‐free...
Encapsulating photogenerated charge‐hopping nodes and space transport bridges within metal–organic frameworks (MOFs) is a promising method of boosting the photocatalytic performance. Herein, this work embeds electron transfer media (9,10‐bis(4‐pyridyl)anthracene (BPAN)) in MOF cavities to build multi‐level electron transfer paths. The MOF cavities are accurately regulated to investigate the significance...
Overexpressed matrix metalloproteinases, hypoxia microenvironment, and metabolic abnormality are important pathological signs of rheumatoid arthritis (RA). Designing a delivery carrier according to the pathological characteristics of RA that can control drug release in response to disease severity may be a promising treatment strategy. Psoralen is the main active ingredient isolated from Psoralea corylifolia...
Hierarchically ordered porous materials with tailored and inter‐connected macro‐, meso‐, and micro‐pores would facilitate the heterogeneous adsorption and catalysis processes for a wide range of applications but remain a challenge for synthetic chemists. Here, a general and efficient strategy for the synthesis of inverse opal metal–organic frameworks (IO MOFs) with a tunable size of macro‐, meso‐,...
Ultraviolet detection is of great significance due to its wide applications in the missile tracking, flame detecting, pollution monitoring, and so on. The nonlayered semiconductor γ‐Bi2O3 is a promising candidate toward high‐performance UV detection due to the wide bandgap, excellent light sensitivity, environmental stability, nontoxic and elemental abundance properties. However, controllable preparation...
Co‐based bimetallic metal–organic frameworks (MOFs) have emerged as a kind of promising electrocatalyst for oxygen evolution reaction (OER). However, most of present works for Co‐based bimetallic MOFs are still in try‐and‐wrong stage, while the OER performance trend and the underlying structure‐function relationship remain unclear. To address this challenge, Co‐based MOFs on carbon cloth (CC) (CoM...
Transition metal oxides (TMOs) have been under the spotlight as promising precatalysts for electrochemical oxygen evolution reaction (OER) in alkaline media. However, the slow and incomplete self‐reconstruction from TMOs to (oxy)hydroxides as well as the formed (oxy)hydroxides with unmodified electronic structure gives rise to the inferior OER performance to the noble metal oxide ones. Herein, a unique...
Pickering emulsions, stabilized by various micro‐ or nanoparticles with different structures, morphologies or other characteristics, possess distinctive properties and versatile functions comparing with classical emulsions stabilized by surfactants. In recent years their applications, especially in the biomedical field, have been carried out extensively and widely such as templates to prepare colloidosomes,...
In recent years, emulsions stabilized by micro‐ or nanoparticles (known as Pickering emulsions) have attracted much attention. Micro‐ or nanoparticles, as the main components of the emulsion, play a key role in the preparation and application of Pickering emulsions. The existence of particles at the interface between the oil and aqueous phases affects not only the preparation, but also the properties...
