We synthesized CoMoO4 nanofibers by electrospinning along with post-heat treatment at different temperatures. CoMoO4 nanofibers show a superior activity for hydrogen evolution reaction (HER)...

2020年1月1日 · In this work, we reported the design and synthesis of oxygen vacancies engineered CoMoO4 nanosheet arrays grown on three-dimension (3D) porous Ni foam (NF) support by hydrothermal synthesis followed by reducing gas heat treatment used H2 or NH 3, and explored their practical application as bifunctional electrocatalysts for water splitting.

2020年8月15日 · Being different from previous nanostructure engineering and hybridization strategy, herein, we reported an anion-cation co-substitution activation of CoMoO 4 for OER through a facile solvothermal treatment of FeCo-Prussian blue analogue (PBA) nanocube in the presence of thiourea and ammonium molybdate.

The full XPS spectra of CoMoO 4 and P-CoMoO 4-x demonstrated that the catalysts were comprised of Co, Mo, and O, corroborating the results of EDX analysis (Fig. S4). The addition P signals in P-CoMoO 4 -x samples revealed that P was doped successfully.

2022年8月11日 · Most V O are localized only within MoO 4 tetrahedrons that are identified by X-ray photoelectron spectra (XPS) and Raman spectroscopy, so that coherent surface reconstruction only occurs at CoO 6 octahedrons in favor of tuning intrinsic activity of pure CoOOH (Figure 1).

The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE. Peak-fits are guides for practical, real-world applications.

In this paper, CoMoO4@Co3O4 composite is prepared by hydrothermal treatment and sintering treatment using ZIF-67 as a self-supporting template. The CoMoO4@Co3O4 electrode shows an excellent...

The CoMoO4-N2 with higher oxygen vacancy concentration exhibits more superior electrochemical performance than CoMoO4-Air, which delivers an ultrahigh specific capacity (999 mA h g⁻¹ after 500...
