“…In addition, the catalytic performance of the magnetic M/CoFe 2 O 4 nanocatalyst was also compared with recent literature in the catalytic hydrolytic dehydrogenation of NaBH 4 . − Figure shows that the catalytic activities of as-obtained magnetic Ru/CoFeO 4 and Pd/CoFe 2 O 4 nanocatalysts are fairly acceptable, with TOFs of 93.5 and 74.8 L H 2 ·g cat –1 ·min –1 (421 and 348 mol H 2 ·mol cat –1 ·min –1 ), respectively.…”

Sodium borohydride (NaBH 4 ) has been widely regarded as the one of most promising further hydrogen (H 2 )generated materials for the safe storage, transportation, and utilization of H 2 . Therefore, the exploration of more efficient catalytic systems for on-demand H 2 evolution via NaBH 4 hydrolysis is critical. Herein, a series of magnetic recyclable cobalt ferrite (CoFe 2 O 4 )-modified transition-metal nanoparticles (including Ru, Pd, Rh, Pt, Ir, and Ag) for the catalytic hydrolytic dehydrogenation of NaBH 4 for H 2 evolution have been developed for the first time. The order of the catalytic activity is Ru > Pd > Rh > Pt > Ir > Ag, indicating that Ru/ CoFe 2 O 4 and Pd/CoFe 2 O 4 are the most active, with turnover frequencies of 421 and 348 mol H 2 •mol cat −1 •min −1 . By comparing with other carriers, we found the key factor to be CoFe 2 O 4 in facilitating H 2 production upon the hydrolytic dehydrogenation of NaBH 4 in this work.

“…In the XRD pattern (Figure S5), compared with Co@150PC, Co@150PC-15th also did not show the characteristic peak of Co-B around 46 • . This is probably because of the presence of heat in the reaction during the test and because the surface of Co nanoparticles is covered by a film consisting of strongly adsorbed (poly)borates [46]. To verify the above results, we conducted FT-IR and Raman tests.…”

As a promising hydrogen storage material, sodium borohydride (NaBH4) exhibits superior stability in alkaline solutions and delivers 10.8 wt.% theoretical hydrogen storage capacity. Nevertheless, its hydrolysis reaction at room temperature must be activated and accelerated by adding an effective catalyst. In this study, we synthesize Co nanoparticles supported on bagasse-derived porous carbon (Co@xPC) for catalytic hydrolytic dehydrogenation of NaBH4. According to the experimental results, Co nanoparticles with uniform particle size and high dispersion are successfully supported on porous carbon to achieve a Co@150PC catalyst. It exhibits particularly high activity of hydrogen generation with the optimal hydrogen production rate of 11086.4 mLH2∙min−1∙gCo−1 and low activation energy (Ea) of 31.25 kJ mol−1. The calculation results based on density functional theory (DFT) indicate that the Co@xPC structure is conducive to the dissociation of [BH4]−, which effectively enhances the hydrolysis efficiency of NaBH4. Moreover, Co@150PC presents an excellent durability, retaining 72.0% of the initial catalyst activity after 15 cycling tests. Moreover, we also explored the degradation mechanism of catalyst performance.

“…Carbon materials are often used as carriers to prepare some supported metal catalysts due to their large pore volume, high surface area, chemical inertness, and good mechanical and thermal stability. [48][49][50] For example, Gyngazova et al [51] used a wetness impregnation method to prepare a series of Ni/C catalysts with different nickel loadings. Among them, after reaction at 180 C for 2 h, the HMF conversion rate and DMF yield of 10 wt% Ni/C catalyst are 100% and 75%, respectively.…”

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

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.
