New insight into electrochemical-induced synthesis of NiAl2O4/Al2O3: Synergistic effect of surface hydroxyl groups and magnetism for enhanced adsorptivity of Pd(II)

“…The experimental procedures of synthesis of NiO were similar to those reported in the literature [16][17][18]. A DMF solution (10 mL) containing 0.1 M tetraethylammonium perchlorate was electrolyzed in the presence of a naphthalene mediator (6 mmol) in a normal one-compartment cell fitted with a Pt plate cathode (2 cm × 2 cm) and Ni plate anode (2 cm × 2 cm) at a constant current density of 120 mA/cm 2 under a nitrogen atmosphere at 273 K. After electrolysis, the mixture was impregnated, oven dried overnight at 378 K, and calcined at 823 K for 3 h to yield a black powder (NiO) for characterization and adsorption testing.…”

“…In fact, the presence of NiO in the Ni/Al 2 O 3 -E was also confirmed by TEM images. Besides isormorphously substituted in the Al 2 O 3 framework, abundance Ni 2+ ions in the electrolysis system were also underwent reduction to produce Ni 0 , which then being oxided to give the NiO by the calcination [17][18][19].…”

Effective Removal of Hexavalent Chromium from Aqueous Solutions Using Ionic Liquid Modified Graphene Oxide Sorbent

“…The techniques used for pollutant removal from wastewater include photodegradation [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] , adsorption 24,[26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45] , electrocoagulation 46,47 , membrane filtration 48,49 , and reverse osmosis 48 . Among these methods, sorption has proved to be an attractive process because of its low cost and ease of operation.…”

Direct in situ activation of Ag0 nanoparticles in synthesis of Ag/TiO2 and its photoactivity

“…Various semiconductors have been used such as TiO 2 , ZnO, SnO, ␣-Fe 2 O 3 , CdS, and ZnS [14][15][16]. Among them, TiO 2 shows better potential due to its strong oxidizing power, chemical-inertness and long-term stability against photo and chemical corrosion.…”
