Catalytic transfer hydrogenation/hydrogenolysis of 5-hydroxymethylfurfural (HMF) to valuable chemicals, 2,5-dimethylfuran (DMF), is realized over a carbon supported nickel-cobalt catalyst with formic acid as hydrogen donor. The highest DMF yield, 90.0%, is achieved at 210°C under self-generated pressure. A reaction route involving 5-methylfurfural (5-MF) instead of 2,5-bis(hydromethyl)furan (BHMF)...
A series of water-tolerant porous niobium phosphate solid acid catalysts were hydrothermal synthesized using cetyltrimethyl ammonium bromide (CTAB) as the template. The tuning of surface acidity and the ratios of acid types (Brönsted and Lewis acid sites) was realized by adjusting the pH values in synthetic processes. It was found that the acidic properties and the balance between Brönsted/Lewis acid...
