Two basic bismuth nitrates: [Bi6O6(OH)2](NO3)4· 2H2O with superior photodegradation activity for rhodamine B and [Bi6O5(OH)3](NO3)5· 3H2O with ultrahigh adsorption capacity for methyl orange

Regular hexagonal CuBi nanosheets boost highly efficient CO2reduction to HCOOH in a solid-electrolyte cell

“…As for XPS spectra of N 1s (Fig. S2 †), the peaks of NO 3 − at 406.6 and 406.5 eV were assigned to Cu-BiOON 4 and BiOON 4 but not for BiO x , 30 which was consistent with the molecular composition of BiOON 4 . In the Cu 2p pattern (Fig.…”

“…2c) could be tted into three peaks, including 529.9, 531.2 and 532.4 eV, which were ascribed to Bi/Cu-O, -OH and N-O, respectively. 30,31 It was noticed that the binding energy of O 1s also had a blue shi compared with BiOON 4 and BiO x samples, which may be derived from the electron donor effect of copper toward the Bi-O bond. As for XPS spectra of N 1s (Fig.…”

A detailed investigation of MnO2 nanorods to be grown onto activated carbon. High efficiency towards aqueous methyl orange adsorption/degradation

“…Many technologies, such as chemical oxidation [15], photochemical/ ultrasonic degradation [16,17], reverse osmosis [18] and flotation [19] have been exploited. Among them, adsorption is one of the most effective methods, due to its easy operation, low cost, availability of a wide range of adsorbents and, above all, because it is a non-destructive technology [20][21][22][23][24]. The most common used adsorbent for wastewater treatment system is bare activated carbon, owing to its large specific surface area [21].…”

Low Carbonate Contaminative and Ultrasmall NiAl LDH Prepared by Acid Salt Treatment with High Adsorption Capacity of Methyl Orange

“…The maximum adsorption capacities of MO on other adsorbents are summarized in Table . As can be seen, the theoretical Langmuir maximum adsorption capacities ( q m,cal ) of Ni 4 Al 1 –Cl LDH prepared by acid salt treatment are much higher than those of other materials such as RGO-NiCr–CO 3 LDH, Ni/Al@PAB, SiO 2 @MgAl LDH, Fe 3 O 4 @polydopamine@MgAl LDH, ZnAl LDO, Cr-doped ZnO, NiFe–NO 3 LDH, Co 4 Al 1 –Cl LDH, amine modified PIM-1 fibers, GO@NiFe LDH, [Bi 6 O 5 (OH) 3 ]·(NO 3 ) 5 ·3H 2 O, modified bentonite, NiO . The adsorption density (Γ, mg m –2 ) can be calculated by the equation Γ = q m / S BET .…”
