Effect of electrodeposition temperature on the electrochemical performance of a Ni(OH)2electrode

Photocatalytic degradation of phenol in water on as-prepared and surface modified TiO2 nanoparticles

“…Recently, many researchers have reported that maximizing light harness by the modification of TiO 2 and improving acidity of the semiconductor are feasible and cost-effective ways to improve the photocatalytic activity of TiO 2 [18][19][20][21][22]. Recently, Mao et al have produced high efficient disordered TiO 2 nanocrystals for the photocatalytic splitting of water via the combination of adding impurities and hydrogenation treatment [19].…”

Graphene based metal and metal oxide nanocomposites: synthesis, properties and their applications

“…346,347 Owing to their high theoretical capacity (2584 F g -1 within 0.5 V for NiO), their low price and excellent pseudocapacitive behavior, both NiO and Ni(OH) 2 have been considered as suitable replacement for the more expensive amorphous RuO 2 . 348,349 However, these materials largely suffer from poor electrical conductivity, low accessible surface areas and volume changes during the cycling process. To address these problems, various strategies were adopted, including the support of graphene to enhance the electrical conductivity and to improve the overall electrochemical performance of the material.…”

High-performance aqueous rechargeable batteries based on zinc anode and NiCo2O4 cathode

“…Both electrode materials are very cheap and have rich natural sources. 8,9 For all these characterizations, such as safe, low cost and environmentally friendly, this battery system can be a good candidate for being a power source for smart grids to store renewable energies such as solar, wind and tide. Moreover, it can also be a choice to level the valley and peak of power supply of the grids.…”
