“…The applied solvents have no obvious influence on the types and relative contents of the elements C and O in the Ni@C catalysts (Figures S5 and S6). In the Ni 2p XPS spectra (Figure ), two typical peaks at 855.6 and 873.8 eV are attributed to Ni 2+ , while the peaks at the binding energies of 853.1 and 870.4 eV are attributed to Ni 0 . , Interestingly, the solvents significantly affect the Ni 0 /Ni 2+ ratios in the Ni@C catalysts. The differences in the Ni 0 /Ni 2+ ratios may be related to the Ni particle size and thickness of the carbon layer.…”

The structural characteristics of metal−organic framework (MOF)-derived materials are strongly influenced by synthesis solvents. Herein, Ni-BTC MOFs were solvothermally synthesized in different solvents, and their derived Ni@C catalysts were achieved through a one-step pyrolysis. The synthesis solvents significantly affect the microstructures and catalytic performance of the Ni@C catalysts during the hydrogenation of phenolic compounds. Remarkably, employing a ternary solvent system composed of deionised water (DI), N,N-dimethylformamide (DMF), and ethylene glycol (EG) in a specific volume ratio leads to the production of a Ni@C-5DI:10DMF:3EG catalyst with unique hollow sphere structures. The catalyst exhibits a larger specific surface area, smaller and uniformly dispersed Ni nanoparticles, higher Ni 0 /Ni 2+ ratio, higher degree of graphitization, and lower density of acidic sites.
