Origins of OER: The metal geometry in cobalt phosphates was modulated from octahedral to tetrahedral by the simple removal of crystal water in Co3 (PO4)2⋅8 H2O. The two materials form an ideal...

2019年11月10日 · Herein, we report in situ stimulated Raman spectroscopy (SRS) of an amorphous cobalt oxide deposited in phosphate electrolyte (CoPi), one of the most active OER catalysts in neutral pH.

2016年2月3日 · In this study, we present a comprehensive optical characterization of Co 3 O 4 and CoO with Raman scattering and Fourier transform infrared spectroscopy (FTIR).

2022年11月4日 · Here, we use well-defined crystalline cobalt oxyhydroxides CoOOH nanorods and nanosheets as model catalysts to investigate the geometric catalytic active sites. The morphology-dependent analysis...

2024年5月1日 · Cyclic voltammetric techniques in conjunction with XRD, XPS and Raman characterizations have demonstrated unambiguously the response of cobalt (II) hydroxide electrode involves a phosphate and hydrogen ion dependent charge transfer process.

Composition of cobalt phosphate and reduced graphene oxide was optimized. High specific capacity of 415.6 C/g was obtained via composition containing 85% Co3 (PO4)2 and 15% rGO.

2024年8月13日 · In this work, a straightforward hydrothermal method is employed to fabricate free-standing nickel molybdate (NMO) with a rod-like nanostructure, onto which 2D nanosheets of cobalt phosphate (CP) are coated using the successive ionic layer adsorption and reaction (SILAR) method.

To this end, we present a reagent-free, easy-use, cost-effective, accurate electrochemical phosphate sensor with a limit of detection of 10.4 nM and sensitivity of 1.18 A/nM to allow continuously...

2022年2月20日 · Herein, a high-efficient carbon-based trifunctional electrocatalyst FeCoP/C is synthesized through a simple one-step supramolecular-assisted method, in which a supramolecular gel structure is formed by phosphoric acid and melamine to allow the efficient and homogeneous incorporation of highly active species.

2019年9月1日 · Modifying TiO 2 nanotube arrays with CoPi, amend the photoelectrochemical efficiency. 10 min of CoPi deposition leading 24% more photocurrent. Relative Raman intensity of B 1g to E g shows a maximum for 10 min of CoPi deposition. By depositing the CoPi, nanotubes wall have been spread and holes have been covered.
