Advanced Carbon‐Based Nanocatalysts and their Application in Catalytic Conversion of Renewable Platform Molecules

“…Metal‐P species [70,72] Regulate acid site [50] Improve metal dispersion and stability [57,61,72,75] Regulate the affinity between carbon matrix and metal precursors [61] Regulate electronic structure of metal [71] Regulate the adsorption/desorption strength of substrate/intermediate [60,76] …”

“…Owing to larger atom radius and lower electronegativity than N atom, the doping of P into the carbon skeleton was greatly hindered [70] . With unceasing attempts, phosphorus‐doped carbon‐supported metal catalysts have made some progress in catalysis [57,60,61,70–76] . The role of P can be divided into two aspects: forming new active species with metals (such as metal‐P species) [70–72] or playing an auxiliary role to adjust the physical and chemical properties of metals, such as increasing the dispersion and stability of metals, [57,61,72,75] adjusting the electronic state of metals, [71] or improving the acidity of carbon matrix [50] .…”

Atom Doping Engineering of Metal/Carbon Catalysts for Biomass Hydrodeoxygenation

“…DFT results show that N,P codoping plays a synergistic role in modulating the electronic properties of the carbon support. Xiong et al synthesized nickel-loaded nitrogen- and phosphorus-modified activated carbon supported catalysts (Ni/N,P-ACs) for the selective hydrogenation of 1,5-dinitronaphthalene. The Ni/N,P-ACs-900 shows good catalytic activity comparable to that of commercial Pd/C catalysts at a mild condition of 100 °C with 95.8% yield of 1,5-diaminonaphthalene.…”
