In this paper, a non‐noble catalyst was prepared by a simple homogeneous precipitation method and could be applied for 5‐hydroxymethylfurfural (HMF) hydrodeoxygenation (HDO) to 2, 5‐dimethylfuran (DMF). The catalyst was characterized by SEM, TEM, XRD, FT‐IR, BET, XPS, ICP and H2‐TPR. The cobalt species in the catalysts dispersed on the surface of boron nitride (BN) evenly. There is a strong interaction between BN and cobalt species in the Co/BN catalysts with vast B−O defects. Under the optimal conditions, HMF can be completely converted and the selectivity of Co/BN catalyst for DMF can reach as high as 91.67 %. It is crucial that the stability of the catalyst was maintained after five cycles by simple centrifugation. Due to its simple preparation process, low cost and high selectivity, the catalyst will be applied widely in the area of industrial catalysis.

“…Therefore, the diameter of the Nyquist curve can be used to roughly judge the charge barriers, and the lower charge barrier exhibits a smaller diameter. [45,46] For CNÀ OH/CeO 2 À NP, it has a smaller semicircle than those of CNÀ OH and CN/CeO 2 À NP, revealing that its photoinduced carriers can migrate excellently.…”

Photocatalysis is an efficient and eco-friendly method of solving the environmental problems, but the low charge separation efficiency of photocatalysts limits their application. Herein, we report the fabrication of CeO 2 /gÀ C 3 N 4 composites via an in-situ growth of CeO 2 on the dispersed gÀ C 3 N 4 sheets (CNÀ OH) in an strong KOH condition, and the resultant CeO 2 /CNÀ OH composites set up a new interface structure, which demonstrate a dramatically boosted the photocatalytic activity compared with CeO 2 /gÀ C 3 N 4 composites by conventional two-step combination method. The decomposition efficiency of CeO 2 /CNÀ OH for 2,4-dichlorophenol (2,4-DCP) degradation comes up to 6 times of bare CeO 2 or gÀ C 3 N 4 . Compared to conventional CeO 2 / gÀ C 3 N 4 , the CeO 2 /CNÀ OH showed 65.9 % and 23.2 % improvement for 2,4-DCP and Cr(VI) removal, respectively. The significantly enhanced photodegradation ascribe to the alkaline modified CNÀ OH and the fabrication of CeO 2 /CNÀ OH n-n type heterojunction, both can improve the charge separation efficiency and increase the reaction active sites. Furthermore, the probable pathway and concreted photocatalytic mechanism for 2,4-DCP degradation are proposed based on the detected intermediate products.

“…However, unlike graphene or GO that has been exfoliated into a single layer, the BN nanosheets are a multilayer structure. 215 Hence, exfoliation to fewer-layered state BN nanosheets is required to increase their effective diameter/thickness ratio. In general, the noncovalent modification corresponds to the exfoliating process of BN nanosheets, and the covalent modification corresponds to the subsequent surface modification process.…”

To solve the coating’s defects and achieve the goal of lightweight heavy-duty anticorrosive coatings, various two-dimensional (2D) nanomaterials are introduced to polymeric coatings to prepare long-term high-performance anticorrosive coatings. In this review, we concluded overall design ideas of the composite corrosion-resistant polymer coatings for a wide range of 2D nanomaterials and typically reviewed the development of graphene, boron nitride (BN), molybdenum disulfide (MoS2), zirconium phosphate (ZrP), MXene (Ti3C2T x ), and binary hybrid nanosheets (0D/2D, 1D/2D, 2D/2D, 3D/2D) in polymeric anticorrosive coatings. Finally, based on the above discussion, the challenges and outlooks in this promising field are featured from the perspective of chemical engineering.
