Cobalt Supported on BN Catalyst with High B‐O Defects and Its Efficient Hydrodeoxygenation Performance of HMF to DMF**

Abstract

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.

Efficient and Selective Hydrogenolysis of 5‐Hydroxymethylfurfural to 2,5‐Dimethylfuran by a Bimetallic Copper‐Palladium Catalyst on a Carbon‐Doped Boron Nitride Support

“…When glucose was added, the bond strength of −NH 2 , −OH and B−N became weaker and less abundant. The bond strength of CuPd/BCN catalysts are relatively low or even disappears compared to the supports, which may be due to the interaction between the metal Cu, Pd, and BCN support [18] …”

“…The bond strength of CuPd/BCN catalysts are relatively low or even disappears compared to the supports, which may be due to the interaction between the metal Cu, Pd, and BCN support. [18] XPS analysis is used to study the elemental composition and chemical state of the catalyst surface. Figure 3a shows that 3d) are caused by NÀ B and NÀ C bonds and NÀ H. [26] Therefore, the XPS results indicate that carbon has been successfully doped into BN, which is consistent with the XRD results.…”

“…[17] Bi et al developed that Co/BN catalysts had a high DMF selectivity (91.67 %), and the catalyst contained many BÀ O defects. Also, there was a strong interaction between the support BN and Co. [18] It has been shown that the doping of heteroatoms in h-BN materials can achieve the tuning of its structure and properties. [19][20] Lu et al reported that carbon doped BN has excellent photocatalytic properties and high selectivity for CO 2 conversion.…”

“…[15][16][17] Particularly, 2D materials, such as graphene, reduced graphene oxide, MoS 2 , MoO 2 , Mo 2 C, WS 2 , and BN, have been used as supports or independently in HDO reactions to produce green chemicals owing to their good catalytic properties. [18][19][20][21][22] Out of the various 2D materials, MXenes have emerged as trending materials in the last decade due to their significant metallic conductivity, hydrophilicity, redox activity, good dispersibility, and photochemical stability, thus offering diverse applications in sensing, energy storage, electromagnetic interference shielding, photocatalysts, environmental remediation, and C-H activation. 23 MXenes are unique layered materials with a M n+1 X n T x formula, where M denotes an early transition metal (Ti, V, Nb, Ta, Cr, Mo, etc.…”
