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.

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) and...

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 study, we designed and prepared petal-like CoMoO4 clusters combined with carbon cloth as an excellent self-standing and binder-free electrode for asymmetric supercapacitors. Due to the...

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.

2020年7月25日 · X-ray photoelectron spectroscopy (XPS) measurements were performed on a VG ESCALAB MKII XPS system, the C1 s peak at 284.8 eV was used as the reference standard. The thickness of CoMoO 4 nanosheets were determined by atomic force microscopy (AFM).

Here, we present a high-performance and durable heterostructure of NiMo/CoMoO 4 for the alkaline HER constructed via a two-pot in situ growth strategy on a nickel foam (NF). The density of active sites and the surface area of the hybrid catalyst augmented almost three-fold compared to those of pristine CoMoO 4.

2022年8月10日 · In this work, we propose to prepare CoMoO 4 precursors by a simple hydrothermal method, and then fabricate N, S co-doped CoMoO 4 nanosheet arrays with atmosphere treatment strategy.

Hydrogen evolution reaction (HER) is a promising clean and renewable energy strategy. Thus, efficient and inexpensive electrocatalysts for HER have attracted considerable attention. Here, we report...

2021年2月10日 · X-ray photoelectron spectroscopy (XPS) was used to examine surface analysis of prepared products. An XPS survey spectrum of Fig. 6a displays the various signal peaks related to Co2p, Mo3d, O1s, and C1s.
