Polyvinylpyrrolidone assisted transformation of Cu-MOF into N/P-co-doped Octahedron carbon encapsulated Cu3P nanoparticles as high performance anode for lithium ion batteries

High Mass Loading of Edge-Exposed Cu3P Nanocrystal in 3D Freestanding Matrix Regulating Lithiophilic Sites for High-Performance Lithium Metal Anode

“…Two peaks with binding energies (BE) of 935.9 and 955.9 eV are assigned to the Cu 2p peaks in oxidized copper derived from surface oxidation in the air. The broad peaks observed at 942.3 and 962.6 eV are assigned as satellite peaks. ,, On the whole, as expected, the XPS results further verify the successful doping of P into the Cu of the Cu@CNF framework.…”

MOF-derived N,S Co-doped carbon matrix-encapsulated Cu2S nanoparticles as high-performance lithium-ion battery anodes: a joint theoretical and experimental study

“…The Cu 2 S@NSC compound was prepared via a MOF derivatization process. As illustrated in Scheme 1, an octahedral shaped N–Cu-BTC precursor was prefabricated by previously reported methods with modifications, 24 and melamine was chosen as the nitrogen source (BTC = benzene-1,3,5-tricarboxylate). Subsequently, a mixture of thioacetamide and N–Cu-BTC precursor was placed in a tube furnace under Ar–H 2 flowing conditions.…”

MOF-derived carbon-coated cuprous phosphide nanosheets for electrocatalytic glucose oxidation

“…In addition, the other two satellite peaks are indicative of the oscillating excitation of high-spin copper ions. 23 In Fig. 4c, the high-resolution C 1s spectrum shows the peaks of graphitic carbon (CC/C–C) as the main component and carbon bonded to phosphorus/nitrogen and oxygen (C–P/C–N and CO).…”
