Inductive effect between atomically dispersed iridium and transition-metal hydroxide nanosheets enables highly efficient oxygen evolution reaction

Amorphous/Crystalline Heterostructured Cobalt‐Vanadium‐Iron (Oxy)hydroxides for Highly Efficient Oxygen Evolution Reaction

“…[5] The design of high-performance catalysts is an important step for efficient OER. Previously, iridium (Ir)-and ruthenium (Ru)based materials [6,7] are often used for OER catalysts, but the scarcity and high cost of these noble metals limit their wide applications. [8,9] Therefore, the development of earth-abundant and inexpensive electrocatalysts, which can reduce the overpotential of OER process, has long been the challenges for practical applications.…”

Tuning the coordination number of Fe single atoms for the efficient reduction of CO2

“…Recently, single-atom catalysts (SACs) have been identified as promising candidates in the field of electrochemical conversion processes. [17][18][19][20][21] This is because the unique features of SACs such as tailorable electronic structure, maximized atomic utilization, and unsaturated coordination environment render them intriguing properties for catalysis dramatically different from their bulk counterparts. 22 To this end, various strategies (e.g.…”

Simple Construction of Amorphous Monometallic Cobalt‐Based Selenite Nanoparticles using Ball Milling for Highly Efficient Oxygen Evolution Reaction

“…As shown in FT‐IR spectra (Figure S4a) of as‐synthesized samples before and after mechanical ball milling, a typical absorption band of SeO 3 2− at 660 cm −1 could be observed, [29] the broad absorption band around 3200 cm −1 belongs to the coordinated H 2 O, and the absorption peak at 1600 cm −1 is indexed to O−H stretching vibration, [30,31] The absorption bands at 1000 cm −1 are assigned to Co−O coordination bonds [32] . As a comparison, for C 4 S‐6 h and C 4 S‐12 h, the intensity of peak at 1600 and 1000 cm −1 became weaker after ball milling than that of C 4 S. Besides, from Raman spectra, it can be seen that there is no obvious difference before and after mechanical ball milling.…”
