Stability study of transition metal oxide electrode materials

The mechanism of water oxidation using transition metal-based heterogeneous electrocatalysts

“…According The primary challenges in the water-splitting reaction for H 2 production lie in the limited activity and stability of electrode materials used for the OER. 160,161 Markovic et al conducted a study on conductive M 1 O x H y , Fe-M 1 O x H y , and Fe-M 1 M 2 O x H y hydr(oxy)oxide clusters (where M 1 = Ni, Co, and Fe; M 2 = Mn, Co, and Cu) to investigate trends in the activitystability relationship. 152 Their findings revealed that by achieving a balance between the rates of Fe dissolution and redeposition over an MO x H y host material, dynamically stable active sites consisting of Fe can be established.…”

“…By comparing the active Fe species in NiFe and pure Fe hydroxide catalysts with the in situ MS technique, it is found that Fe(IV) exists in the NiFe hydroxide catalyst under OER conditions, but not in the pure Fe hydroxide catalyst. 284 Based on the Mo ¨ssbauer sources of the synchrotron, in situ/operando research makes it possible to collect high-quality data with high local resolution using isotopes such as 61 Ni and 161 Dy that are difficult to obtain under different thermal, electrochemical and material manufacturing conditions.

Nanocrystalline Cellulose-Supported Iron Oxide Composite Materials for High-Performance Lithium-Ion Batteries

“…Transition metal oxides (TMOs) (e.g., MnO 2 , ZnO, Fe 2 O 3 , Fe 3 O 4 , and SnO 2 ) have become mainstream electrode materials in the field of lithium-ion batteries (LIBs) due to their high theoretical capacity [ 1 , 2 , 3 , 4 ]. Among them, iron oxide (Fe 2 O 3 ) has been attractive and extensively considered as an ideal alternative electrode material because of its high theoretical capacity (1007 mAh g −1 ), low conversion voltage, and good stability as well as environmental friendliness [ 5 , 6 ].…”

Ni–Co–Mn complexed 3,4,9,10-perylenetetracarboxylic acid complexes as novel organic electrode materials for lithium-ion batteries

“…[25][26][27] Among many organic structures, the coordination network formed by transition metal cations and organic functional groups is considered as a very promising electrode material (MOC). [28][29][30][31][32][33][34][35][36][37][38][39][40][52][53][54][55] For example, Tian et al 41 used a hydrothermal method to prepare two isomeric POM-based complexes and investigated the electrochemical behavior and dye adsorption properties of the complexes. In addition, an aqueous zinc ion battery was constructed in which one of the complexes was used as the cathode, and the experimental results indicated that this material has good storage performance and cycling stability.…”
