Nanocomposite of nickel benzene‐1,3,5‐tricarboxylic acid metal organic framework with multiwalled carbon nanotubes: A robust and effective electrocatalyst for oxygen evolution reaction in water splitting

“…This decrease in overpotential value of Ni-BTC-MWCNTs-a is due to decomposition of composite in the presence of high temperature and air that results in the oxidation of nickel metal into nickel oxide, CO into CO 2 , and NO into NO 2 and making the decomposed composite an excellent electrocatalyst with properties such as uniform particle size, vast surface area, complete association between the active sites and reactants, increased conductivity, making movement of atoms easy through crystal lattice, and having maximum exposed active sites. 38,44 To show the transfer of the electrons, the electrocatalytic mechanism is discussed in Equations ( 4)-( 7) Jabbar et al [46] 2 Ni-MOF@CNT 370 138.2 Sreekanth et al [47] 3 FeNiNH 2 BDC-5w% CNTs 220 68.50 Yaqoob et al [6] 4 FeNiS-MWCNT 260 50 Kumar and Maiyalagan [48] 5 NiO-CNT 301 --Roy et al [49] 6 Cobalt grown CNTs 380 91.5 Ali et al [50] 7 NiCo-MWCNTs 340 85.5 Ali et al [51] 8 O-CNTs 360 47.7 Li et al [52] 9 25w% AuNiNXZ and 25w% MWCNTs 210 48 Amiripour et al [53] 10 Ni@ graphene 370 66 Ai et al [39] 11 NFM-2 360 98 Wang et al [54] 12 NiCo/Fe 3 O 4 /MOF-74 238 29 Wang et al [55] 13 ZnCo 2 O 4 @C-MWCNTs 327 65 Liu et al [56] 14…”

Recent Advances in Graphene Oxide‐Based Membranes for Heavy Metal Ions Separation

“…Among these approaches, adsorption has got significant interest of the scientific community worldwide, and is widely investigated in industrial applications due to its simplicity, cost effectiveness, uniformity, insensitivity of contaminations, and a smaller number of contaminants [88]. Up to date, a variety of traditional materials including orange peel [89], bagasse fly ash, sawdust [90], neam leaf [91], rice husk [92], red mud [93], activated carbon [94], conducting polymers [95], carbon nanotubes (CNTs) [96][97][98][99], etc. have been investigated as absorbents for removal of heavy metal ions.…”
