Nickel carbonate Hydroxide-based Core-Triple-Shelled nanofibers with ultrahigh specific capacity for flexible hybrid supercapacitors

Nickel carbonate (Ni2(CO3)3) as an electrocatalyst and photo-electrocatalyst for methanol electro-oxidation

“…Furthermore, nickel carbonate complexes have been widely employed for different applications namely: water oxidation reactions, 28 photocatalytic hydrogen generation, 29 nitrite oxidation, 30 and storage applications like batteries and supercapacitors. 31,32 This is related to the superior surface adsorption properties, 33 tendency to show high synergistic interaction with the nearby heteroatom, 34 cost effectiveness, relative abundance, benign environmental properties, 35 electrical conductivity, 36 and heat resistivity. 35 To the best of our knowledge, electrochemically deposited (Ni 2 (CO 3 ) 3 ) has not been reported for the electrochemical methanol oxidation reaction.…”

Construction of Double-Shell Basic Cobalt/Nickel Carbonate Microspheres via MOFs Etching Strategy for Boosting Aqueous Supercapacitor Performances

“…In addition, the energy density of the HSC is also higher than that of other hydroxycarbonate materials and AC-assembled supercapacitor devices, exhibiting an energy density of 41.8 Wh kg –1 at a power density of 0.8 kW kg –1 (Figure g; Table S2). ,,,,− In order to explore the cycling stability of HSC, the device was tested on the LAND battery test system. The results showed that after 5000 cycles, the HSC presents excellent cycling performance of 60% retained.…”

A green synthetic approach: crystalline–amorphous interface CoFe-LDH as a sustainable electrocatalyst for water oxidation with low cell voltage and evaluation of its sustainability standards

“…13 The resulting XRD for the x $yH 2 O), which contains carbonate ions and hydroxyl ions in the interlayer which is in agreement with the XRD, IR, and XPS results. [14][15][16][17] The (003) basal spacing (7.6 Å) plane indicated that CO 3 2− acted as the charge compensating anion in the CoFe-LDH because CO 3 2− has higher affinity for positively charged brucite-like layers. 18 The XRD peaks are noticeably weaker, indicating that the material has relatively poor crystallinity.…”
