Co nanoparticles encapsulated in nitrogen-doped carbon
2022年4月5日 · The XPS peak shift may be attributed to these reasons: the formation of cobalt nanoparticles which caused the microenvironment changes around the Co atom; a higher electron density of Co atoms in CoBDC-NF-NH 3 than in CoBDC-NF-air-450; or the movement of the electronic cloud caused by the electrostatic attraction between Co and N-doped carbon.
Terephthalate and trimesate metal–organic frameworks of Mn, Co, …
The XPS analysis predicted significant changes in the oxidation state of metal nodes for many MOFs with the presence of Ni 3+ as a dominant species in the Ni-based MOFs. Moreover, XPS spectroscopy could trace ligand decomposition and decarboxylation in trimesate and terephthalate-based MOFs, respectively.
Two‐Dimensional Metal–Organic Frameworks‐Based …
XPS confirmed that the hybridization with Ti 3 C 2 T x did not induce the change of the oxidation states of Co species in CoBDC. Notably, the conductive Ti 3 C 2 T x NSs play a key role by altering the OER to a reaction-limited process with significantly enhanced charge transfer kinetics.
XPS spectrum of CoBDC-NF-NH 3-650, we can notice a 1.3-eV shift to higher energy compared with those peaks in CoBDC-NF-air-450. The XPS peak shift may be attributed to these reasons: the formation of cobalt nanoparticles which caused the microenvironment changes around the Co atom; a higher electron density of Co atoms in CoBDC-NF-NH 3 3 CoBDC ...
