We developed a single-step thermal method that enables successful inclusion of ZnO components in the porous boron-carbon-nitrogen (BCN) framework to form a new class of functional hybrid. ZnO-containing BCN hybrids were prepared by treating a mixture of B2O3, glycine, and zinc nitrate at 500 °C. Glycine-nitrate decomposition along with B2O3 acts as a source for ZnO-BCN formation. The incorporation of ZnO onto BCN has extended the photoresponse of ZnO in the visible region, which makes ZnO-BCN a preferable photocatalyst relative to ZnO upon sunlight exposure. It is interesting to note that as-prepared 2D ZnO-BCN sheets dispersed in PDMS form a stable coating over aluminum alloys. The surface exhibited a water contact angle (CA) of 157.6° with 66.6 wt % ZnO-BCN in polydimethylsiloxane (PDMS) and a water droplet (7 μL) roll-off angle of <6° and also demonstrates oil fouling resistant superhydrophobicity. In brief, the present study focuses on the gram scale synthesis of a new class of sunlight-driven photocatalyst and also its application toward the development of superhydrophobic and oleophobic coating.

With the rapid development of nuclear industry, nuclear energy, as a kind of low-carbon energy, has been widely used in the world. However, in the development and application of nuclear energy, a large amount of radionuclides, especially the radioactive uranium, have been inevitably discharged into the environment, causing serious environmental pollution and having great harm to human health. Layered double hydroxides (LDHs) have become the excellent adsorbents in environmental pollution treatments due to easy preparation, large specific surface area, the unique nanostructure and excellent ion exchange capacity. Hence, the preparation of layered double hydroxides and their composites for the efficient removal of radioactive uranium is one of the hot issues in the field of environmental science, which include coprecipitation, ion exchange, hydrothermal method, the urea hydrolysis method, aerogel, microwave-crystallization and separate nucleation/crystallization isolation method. Besides the aforementioned methods, other reported synthesis methods of LDHs include the secondary intercalation method (an intercalation method involving dissolution and the re-coprecipitation method), reconstruction method based on the "memory effect", N 2 protection synthesis, mechanochemical synthesis, surface synthesis, template synthesis, and others. The modification methods of layered double hydroxides can be divided into calcination, intercalation and compounding method, which significantly increase the active sites and further improve the adsorption performance of the materials to radioactive uranium. In addition, the adsorption mechanism has been thoroughly investigated with spectroscopic analysis techniques such as Fourier transformed infrared spectroscopy (FT-IR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Extended X-ray absorption fine structure (EXAFS). In conclusion, the review briefly discuss the application prospects of layered double hydroxides and their composites in the treatment of water pollution, which provide definitive reference values for the further research and practical application of environmental management in the future.

Hexagonal boron nitride (hBN), which is a 2D layered dielectric material, sometimes referred as “white graphene” due to its structural similarity with graphene, has attracted much attention due to its fascinating physical properties. Here, for the first time the use of chemical vapor deposition ‐grown hBN films to fabricate ultrathin (≈3 nm) flexible hBN‐based resistive switching memory device is reported, and the switching mechanism through conductive atomic force microscopy and ex situ transmission electron microscopy is studied. The hBN‐based resistive memory exhibits reproducible switching endurance, long retention time, and the capability to operate under extreme bending conditions. Contrary to the conventional electrochemical metallization theory, the conductive filament is found to commence its growth from the anode to cathode. This work provides an important step for broadening and deepening the understanding on the switching mechanism in filament‐based resistive memories and propels the 2D material application in the resistive memory in future computing systems.
