Researchers from Harvard University Report Findings in Physical Chemistry (Spectroscopic Studies of Nanoparticulate Thin Films of a Cobalt-Based Oxygen Evolution Catalyst)

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Physical Chemistry have been published. According to news reporting originating in Cambridge, Massachusetts, by NewsRx journalists, research stated, "Nanoparticle (NP) cobalt-phosphate (Co-P-i) water oxidation catalysts are prepared as thin films by anodic electrodeposition from solutions of Co2+ dissolved in proton-accepting electrolytes. Compositional and structural insight into the nature of the catalyst film is provided from advanced spectroscopy."

The news reporters obtained a quote from the research from Harvard University, "Infrared spectra demonstrate that counteranions incorporate into the Co-P-i thin films and that the phosphate ion, among various anion electrolytes, exhibits the highest binding affinity to the cobalt centers. Atomic force microscopy images show a highly porous morphology of the thin film that is composed of Co-P-i NPs. Whereas conventional X-ray powder diffraction technique shows catalyst films to be amorphous, synchrotron-based X-ray grazing incidence diffraction reveals well-defined diffraction patterns that are indicative of long-range ordering within the film."

According to the news reporters, the research concluded: "Azimuthal scans imply that as-prepared films possess a highly preferred orientation and texture on the electrode surface."
