Electrical Aspects of Adsorbing Colloid Flotation. X. Pretreatments, Multiple Removals, Interferences, and Specific Adsorption

Formation of Graphene‐Wrapped Nanocrystals at Room Temperature through the Colloidal Coagulation Effect

“…The GO ( Figure b) that served as the ions in CCE is negatively surface charged through wet‐chemical oxidation method, the major challenge in achieving coagulation is to get MCNCs with positive surface charge. As we know, according to Fajans rule, when two or more types of ions are available for adsorption, and other factors are equal, the ions that form the compound will be adsorbed preferentially . Therefore, when the colloid particles of metal compound are dispersed into soluble salt solution containing the same metal cation M n + , the M n + will be absorbed on the surface of MCNCs (Figure a,b), which results in these nanoparticles being positively charged.…”

In Situ Coupling of Colloidal Silica and Li Salt Anion toward Stable Li Anode for Long-Cycle-Life Li-O2 Batteries

“…According to the Fajans rule, the silica colloid particles are prone to adsorbing the ions which have the same properties as SiO 2 . 28 Also, the weak solvation of anion can also assist CF 3 SO 3 À adsorption because the Li + ion, which is coordinated to four oxygen atoms within G4 molecules, is difficult to adsorb on the surface of colloid nucleus. 29 We conjectured that CF 3 SO 3 À is adsorbed on the SiO 2 surface as Fig- ;…”

A Brief Review of the Synthesis and Catalytic Applications of Graphene‐Coated Oxides

“…Fe 2 O 3 ) are dispersed into a solution which contains the same metal cations (i.e. Fe 3+ ), the metal cation will be absorbed on the surface of the metal oxide according to the Fajans rule to form positively‐charged metal oxide particles . When these positively‐charged particles are mixed with a negatively‐charged GO solution they will be covered by GO due to electrostatic interactions.…”
