“…[18][19][20] Many of them, such as endocrine disrupting chemicals, pharmaceuticals, personal care products, and other persistent organic compounds show biological toxicity, environmental persistence, and bioaccumulation. [21] Tetracycline hydrochloride (TC) is one of the most common broad-spectrum antibiotics widely used in medicine, animal husbandry, aquaculture, and agricultural production due to its inactivation of various pathogenic bacteria and harmful microorganisms. [22][23][24][25][26] However, most antibiotics are difficult to be fully digested and absorbed by humans and animals, and >80% are excreted in the form of feces and urine, accumulating in the ecosystem.…”

It is highly desirable to develop facile methods to improve the processability of porous materials for industrial applications. Herein, the preparation of a novel near‐infrared emitting hybrid aerogel (PCS‐CA) is reported by physically blending a porous material with chitosan. The applied porous material (PCS‐CZ‐O‐DCM) is obtained from a near‐infrared emission semiconductor compound (CZ‐O‐DCM) and octavinylsilsesquioxane (OVS). PCS‐CZ‐O‐DCM can detect tetracycline hydrochloride selectively and rapidly in various solution with an extremely low detection limit of 0.29 µm for fluorescence quenching. It also exhibits an outstanding sunlight‐driven photodegradation activity for antibiotics even in the absence of additional oxidation agents or pH control. PCS‐CA also performs better than PCS‐CZ‐O‐DCM powder. A PCS‐CA‐based glass device is further fabricated, which enables a larger amount of water purification of antibiotics by a continuous flow‐through system by light‐driven degradation. By blending with a soft polymer matrix, improved processability can be applied to insoluble porous materials. As a result, a novel functional devices can be realized which provides a new way to apply insoluble porous materials.

The unique tribological characteristics of black phosphorus quantum dots (BPQDs) have recently attracted much attention. However, the long-term stable lubrication of BPQDs and prevention of degradation in ultrapure water remain huge challenges. Herein, BPQDs@silica (BPQDs@SiO2) core–shell materials were designed and synthesized. The BPQDs are uniformly distributed in the SiO2 shell. The as-prepared BPQDs@SiO2 as the water-based lubrication additive has remarkable lubricity, wettability, and stability. In particular, compared with the average coefficient of friction (COF) and wear rate of ultrapure water, those of BPQDs@SiO2, being a water-based lubrication additive, could be reduced by 45.7 and 83.0% at 10 N and 150 r/min, respectively. The lubrication mechanisms of BPQDs@SiO2 as a water-based lubrication additive were proposed based on the friction test and wear surface analysis. The excellent lubricity performances of BPQDs@SiO2 are owed to the polishing of the SiO2 shell, the extreme pressure property of the BPQD core, and the tribo-chemical reaction film. This investigation established a simple, convenient, and feasible method for using the BPQDs@SiO2 materials as a water-based lubrication additive. It is expected that BPQDs with a core-shell nanostructure will open up new ideas for the development of excellent lubricating nanomaterials.

“…BP offers advantages such as low toxicity, tunable band gap, and facile functionalization. , In 2018, we first proposed that BP possessed CL properties and developed analytical platforms for explosives and reactive radicals. − However, practical applications of BP in CL sensing were limited by relatively weak emission and an unknown intrinsic luminescence mechanism.

The development of chemiluminescence-based innovation sensing systems and the construction of a sensing mechanism to improve the analytical performance of compounds remain a great challenge. Herein, we fabricated an advanced oxidation processes pretreated chemiluminescence (AOP-CL) sensing system via the introduction of cobalt-modified black phosphorus nanosheets (Co@BPNs) to achieve higher efficient thiabendazole (TBZ) detection. Co@BPNs, enriched with lattice oxygen, exhibited a superior catalytic performance for accelerating the decomposition of ferrate (VI). This Co@BPNs-based ferrate (VI) AOP system demonstrated a unique ability to selectively decompose TBZ, resulting in a strong CL emission. On this basis, a highly selective and sensitive CL sensing platform for TBZ was established, which exhibited strong resistance to common ions and pesticides interference. This was successfully applied to detecting TBZ in environmental samples such as tea and kiwi fruits. Besides, the TBZ detection mechanism was explored, Co@BPNs-based ferrate (VI) AOP system produced a high yield of ROS (mainly 1 O 2 ), which oxidized the thiazole-based structure of TBZ, generating chemical energy that was transferred to Co@BPNs via a chemical electron exchange luminescence (CIEEL) mechanism, leading to intense CL emission. Notably, this study not only proposed an innovative approach to enhance the chemical activity and CL properties of nanomaterials but also offered a new pathway for designing efficient CL probes for pollutant monitoring in complex samples.
