催化剂制备:对于 Bi:x%In/C(x = 0、5、10、15、20)(此处的 x % 代表初始进料中In和Bi的摩尔比),将 1.1764 g(4 mmol)C6H5Na3O7∙2H2O 加入装有 100 mL 去离子水的锥形瓶中,使其充分溶解和混合,然后加入指定摩尔比的 BiCl3 和 InCl3-4H2O。搅拌 0.5 小时后,向混合物中加入 0.05 克 XC-72...
SM3–SM7), H2O2and Cl2are used by adding a certain concentration for the elimination of ARBs and ARGs. They achieve elimination efficiencies between 70 and 100% in 10 to 30 min of treatment, with different efficiencies depending on the disinfectant...
Following this procedure, 2.5 g of zeolite 13X are dissolved in a 0.2 M copper-ammonia solution, which is formed by adding 15 mL of 28 vol% ammonium hydroxide (NH4OH) solution to 110 mL of 0.2 M Cu(NO3)2 ∙ 3H2O aqueous solution. The suspension is continuously stirred at room ...
Iron(III) nitrate nonahydrate (Fe(NO3)3∙9H2O, 200 mg), glucose (C6H12O6, 200 mg) and ammonium sulfate ((NH4)2SO4, 600 mg) were used as the precursors of iron, carbon and nitrogen, respectively. The precursors were mixed with 3 ml of Milli-Q water and ultrasonicated for 10 min....
以SrCO3、SrF2、Sc2O3和Mn(NO3)2∙6H2O为原料, 充分研磨后于1200 ℃下煅烧制得。如图7(a)所示, 在Sr2ScO3F中, Sc3+与5个O2-+1个F-形成ScO5F八面体[27];如图7(b)所示, Mn4+在Sr2ScO3F中表现出低光子能量发光且热猝灭现象严重。当Mn4+取代Sc3+时可能的电荷补偿机制是O2-取代F-而形成MnO6八面...

(1). All samples were prepared in D2O, whereas DNO3 and NaOD were used to adjust the pH. All solutions were prepared as 0.1 M NaGluc and let equilibrate for 3 days. Provided the very slow kinetics of the lactonization/hydrolysis reactions, the lactone 13C NMR peaks (both for γ-H...
Generally, the chemical formula of LDHs can be written as [M2+1−xM3+x(OH)2]x+(Xn−)x/n·mH2O (Xn− = Cl−, NO3−, Br−…) (short form M2+M3+-X-mH2O). The water molecules and the anions (Xn−) were intercalated between the [M2+1−xM3+x(OH)2]x+ layers [...
