Nanowire-structured FeP-CoP arrays as highly active and stable bifunctional electrocatalyst synergistically promoting high-current overall water splitting

Hollow CoP Encapsulated in an N-Doped Carbon Nanocage as an Efficient Bifunctional Electrocatalyst for Overall Water Splitting

“…Regarding the XPS spectrum of P 2p, the doublet situated at 129.5 and 130.2 eV is attributed to P 2p 3/2 and P 2p 1/2 in Co–P, respectively. And the other peak at 133.8 eV can be indexed to spontaneous oxidized P–O species in air. , As depicted in Figure c, the spectrum of C 1s can be fitted to a series of peaks at 284.5, 285.6, 286.6, 288.1, and 290.0 eV, which can be identified as CC, C–C, C–O/C–N, CO/CN, and C satellite peak. − In the high-resolution N 1s XPS spectrum (Figure d), four deconvoluted peaks of pyridinic N (398.1 eV), pyrrolic N (399.1 eV), graphitic N (400.9 eV), and oxidized N (403.8 eV) are observed, signifying the successful doping of N into a carbon matrix. The heteroatom site is also regarded as efficient anchors to bind a CoP nanoparticle with strong interaction for efficient electrocatalysis …”

Hypercrosslinked polymer-mediated fabrication of binary metal phosphide decorated spherical carbon as an efficient and durable bifunctional electrocatalyst for rechargeable Zn–air batteries

“…For the FeCoP/NPC composites, four diffraction peaks at 37.1°, 48.3°, 56.1° and 59.6° can be attributed to the (111), (211), (031) and (002) crystal planes of FeP (JCPDS No. 39-0809), 33 and the diffraction peaks at 31.6°, 46.2°, 48.1° and 56.8° can be attributed to the (011), (112), (211) and (301) crystal planes of CoP (JCPDS No. 29-0497), 33 indicating the existence of both FeP and CoP nanoparticles (Fig.…”

Self-supported porous heterostructure WC/WO3−x ceramic electrode for hydrogen evolution reaction in acidic and alkaline media

“…Hydrogen is a clean, sustainable, and zero-carbon emission energy source, which is widely considered to replace traditional fossil fuels [5][6][7]. Large scale production of high-purity hydrogen can be obtained by the electrolysis of water [8,9]. Platinum (Pt)-based noble metals are the most effective hydrogen evolution reaction (HER) electrocatalysts, but their high cost and insufficient natural resources severely limit their wide application [10].…”
