Oxygen vacancies in oxide materials, although demonstrated to be beneficial for many applications, are hard to be generated and manipulated as desired, particularly for bulk materials with a large size and limited surface area. Here, by simply coupling the thermal activation with a simultaneously applied electric field, we efficiently generate ordered oxygen vacancies within bulk crystals of ternary SrAlO, binary TiO and other common oxide materials, which give rise to superior functionalities. We expect that this approach offers a general and practical way for the vacancy engineering of oxide materials and holds great promise for their applications.

Carbenes are critical intermediates in organic chemistry, recognized for their exceptional reactivity and versatility. However, conventional methods for carbene generation are often associated with safety risks and hazardous procedures. This study presents a Ga-ZnO nanosheets photocatalyst with a (100) preferred orientation, featuring abundant refined frustrated Lewis pair (FLP) sites, excellent light absorption, and efficient charge transport properties.

Traditional biological detection methods rely on signal amplification strategies such as enzymatic catalysis or nucleic acid amplification. However, their efficiency decreases in low-temperature environments, compromising their detection sensitivity. To break the loss of enzyme catalytic activity at low temperatures, research on cold-adaptive nanozymes has attracted much attention.

Doping guest materials into host materials with a confined space to suppress nonradiative decay is an effective strategy for achieving room-temperature phosphorescence (RTP). However, constructing host-guest doped materials with ultralong RTP (URTP) is still challenging. Herein, by embedding three coumarin derivatives into boric acid via one-step heat treatment, the URTP material with an afterglow lasting up to 60 s, a phosphorescence lifetime of 1.

Catalyst deactivation poses a significant challenge in environmental remediation, especially for the photocatalytic oxidation of chlorinated volatile organic compounds (Cl-VOCs). In this study, a functional flower-like TiO@Mn/rGO (FTMG) catalyst coupled with a vacuum ultraviolet (VUV) lamp was used as a novel photocatalytic oxidation (VUV-PCO) system for chlorobenzene (CB) oxidation. In this system, more than 80% of CB was efficiently oxidized at a high w8 hly space velocity of 600,000 g h, which was a 6.

Developing ideal photocatalysts for energy regeneration and environmental remediation by combining the advantages of individual semiconductors remains a significant challenge. Herein, tungsten trioxide (WO)/CuSnS S-scheme heterojunction composite photocatalysts are developed. Initially, doped oxygen vacancy (OV) was prepared on two-dimensional WO nanosheets by direct calcination method.
