Electrochemical synthesis of monodispersed and highly alloyed PtCo nanoparticles with a remarkable durability towards oxygen reduction reaction

Confinement Effects in Carbonized ZIF-Confined Hollow PtCo Nanospheres Enable the Methanol Oxidation Reaction

“…It is worth noting that the binding energies of Pt 4f 7/2 and 4f 5/2 for PtCo@carbonized ZIF-8, PtCo@ZIF-8, and the PtCo NPs shift to lower positions compared to those of Pt@ZIF-8. These results indicate that the incorporation of Co can effectively adjust the electronic structure of Pt, thus leading to an electron-rich structure on the PtCo NPs . Importantly, the XPS results demonstrate that there is no effect on the electronic structure of the PtCo NPs when they exist within ZIF-8 or its carbonized structure.…”

Active-site stabilized Bi metal–organic framework-based catalyst for highly active and selective electroreduction of CO2 to formate over a wide potential window

“…44-1246). This phenomenon may be due to the reducing properties of DMF, 36 which can reduce a part of the Bi species in Bi-MOF at a higher temperature.…”

“…. This phenomenon may be due to the reducing properties of DMF, 36 which can reduce a part of the Bi species in Bi-MOF at a higher temperature. The morphologies of as-obtained Bi-BDC-T materials are observed by SEM in Fig.…”

Monodispersed PtCo alloy nanoparticles with a modulated d-band center exhibiting highly efficient hydrogen evolution

“…The binding energy of N 1s in PtCo-NC is slightly positively shied aer the formation of PtCo alloys compared to Pt-NC and Co-NC, suggesting that N interacts during the formation of PtCo alloys and provides electrons to PtCo alloys. 44 In addition, the remaining Pt 2+ may be derived from the oxidation of metallic Pt(0) by air. 45 2 .…”
