Electrocatalytic Hydrogen Evolution
In article number 2309830, Dekui Shen, Chongbo Cheng, Paul J. Dyson, and co‐workers used Ginkgo leaves as the source of functional carbon support materials, used to immobilize Fe/FeP nanocatalysts, which show outstanding performance in the hydrogen evolution reaction.
Iron/iron phosphide nanospheres supported on ginkgo leaf‐derived carbon (Fe&FeP@gl‐C) are prepared using a post‐phosphidation approach, with varying amounts of iron (Fe). The activity of the catalysts in the hydrogen evolution reaction (HER) outperforms iron/iron carbide nanospheres supported on ginkgo leaf‐derived carbon (Fe&FexC@gl‐C), due to enhanced work function, electron transfer, and...
To address the mechanism of C–C bond cleavage on the metal surface of the M/SiO2 (M represents metal) catalyst is desirable and vital during the catalytic depolymerization process of lignin in solvents. Density functional theory simulation is used to determine the energy of C–C bond dissociation, adsorption geometry, adsorption energy and electronic structures of three kinds of the β-1 bond contained...
Methanation of syngas (H2/CO) in a fixed-bed down-flow reactor under atmospheric atmosphere was investigated over a series of Ni-based catalysts with Fe and TiO2 as the support. The prepared catalysts (Ni/Al2O3, Ni-Fe/Al2O3, and Ni-Fe/TiO2-Al2O3) were characterized by N2 adsorption-desorption, X-ray diffraction (XRD), temperature-programmed reduction (TPR) and X-ray photoelectron spectroscopy (XPS)...
