“…Recently, nitrogen-doped carbon has been studied and developed for heterogeneous catalytic reactions [35]. Nitrogen doping can significantly increase the electron density of states (DOS) of inert carbon carriers [18], reduce the electronic spin density of metal nanoparticles, and improve the oxidation resistance of metal nanoparticles [36]. Furthermore, the electronic interaction between nitrogen-doped carbon and active metal is strengthened, effectively enhancing the stability and promoting the catalytic activity of the metal catalyst [37][38][39][40].…”

Metal-supported catalyst with high activity and relatively simple preparation method is given priority to industrial production. In this work, this study reported an easily accessible synthesis strategy to prepare Mott-Schottky-type N-doped carbon encapsulated metallic Co (Co@Np+gC) catalyst by high-temperature pyrolysis method in which carbon nitride (g-C3N4) and dopamine were used as support and nitrogen source. The prepared Co@Np+gC presented a Mott-Schottky effect; that is, a strong electronic interaction of metallic Co and N-doped carbon shell was constructed to lead to the generation of Mott-Schottky contact. The metallic Co, due to high work function as compared to that of N-doped carbon, transferred electrons to the N-doped outer shell, forming a new contact interface. In this interface area, the positive and negative charges were redistributed, and the catalytic hydrogenation mainly occurred in the area of active charges. The Co@Np+gC catalyst showed excellent catalytic activity in the hydrogenation of phenylacetylene to styrene, and the selectivity of styrene reached 82.4%, much higher than those of reference catalysts. The reason for the promoted semi-hydrogenation of phenylacetylene was attributed to the electron transfer of metallic Co, as it was caused by N doping on carbon.

“…In the direct hydrogenation reaction, the H 2 was dissociated on the Co metal active sites to form Co–H containing activated hydrogen species (H*). FF is activated by the electrophilic adsorption between the electrons from carbonyl group and the positively charged Co. 46 Especially due to the oxophilic properties of Co, the carbonyl O was adsorbed in the form of η 1(O)-aldehyde configuration onto Co(111). Then H* of Co–H attacks the C and O of carbonyl, 47,48 forming FA.…”

“…Nitrogen-doped carbon materials have attracted more and more interest because of their excellent features. [59][60][61] The doping of nitrogen can introduce basic sites and provide metal nanoparticle anchor points for metal single-atom catalysts and inhibit metal aggregation. Wang et al [62] synthesized the Mott-Schottky-type nitrogen-doped graphene shell-coated metal cobalt (Co@NGs) nanocatalyst by using glucose as the carbon source and melamine as the nitrogen source through a combination of hydrothermal and carbonization methods.…”

Catalytic Upgrading of Bio‐Based 5‐Hydroxymethylfurfural to 2,5‐Dimethylfuran with Non‐Noble Metals

et al. 2021

View full text Add to dashboard Cite

2,5-Dimethylfuran (DMF) is considered one of the most promising liquid transport fuels due to its high energy density, high boiling point, high octane number, and immiscibility with water. It can be obtained mainly by hydrogenolysis of biomass-derived 5-hydroxymethylfurfural (HMF) over metal catalysts. This review describes the latest research progress of developing various nonnoble metal catalytic materials for hydrogenolysis of HMF to produce DMF. The effects of different carriers (e.g., carbon materials, nitrogen-doped carbon materials, and metal oxides), the bimetallic synergistic effect, and catalyst type on the catalyst activity are systematically introduced. The reaction paths of producing DMF from HMF affected by reaction parameters such as non-noble metals, hydrogen donors, and temperature are discussed. In addition, potential directions for the large-scale industrial production and application of DMF are proposed.
