Embodiment 1

[0097] Synthesis of copper silicate SCuS-10 (hollow)

[0098] Preparation contains Na 2 SiO 3 、CuSO 4 , NaOH, KCl, NaCl and DDW (deionized distilled water) gel, wherein, the SiO in the gel 2 :CuSO 4 :Na 2 O:KCl:NaCl:H 2 The molar ratio of O is 2.8:1:2.2:7.4:5:400. The gel can be prepared as described below. Preparation of Si source solution: During stirring, by adding 5 to 20 g Na 2 SiO 3 NaOH solution (0.2 to 4 g NaOH and 20 to 35 g DDW), KCl solution (5 to 10 g KCl and 20 to 35 g DDW), and NaCl solution (5 to 15 g NaCl and 20 to 30 g DDW) were added successively to . By adding CuSO 4 Or copper acetate (1 to 6 g) was dissolved in DDW (20 to 60 g) to prepare a Cu source solution. The two solutions were mixed with each other and aged at room temperature for 14 hours. 0.1 to 0.5 g of seeds of the desired AM-6 molecular sieve are added after maturation. The gel was transferred to a 50 ml polytetrafluoroethylene lined reaction kettle, which was heated under steady co...

[0101] The synthesis of copper silicate SCuS-10

[0102] Preparation contains Na 2 SiO 3 、CuSO 4 , NaOH, KCl, NaCl, glucose and DDW (deionized distilled water) gel, wherein the SiO in the gel 2 :CuSO 4 :Na 2 O:KCl:NaCl:Glucose:H 2 The molar ratio of O is 2.4:1:2:7.4:5.3:0.2:400. The gel can be prepared as described below. Preparation of Si source solution: During stirring, by adding 5 to 20gNa 2 SiO 3 NaOH solution (0.2 to 4g NaOH and 20 to 35g DDW), KCl solution (5 to 10g KCl and 20 to 35g DDW), NaCl solution (5 to 15g NaCl and 20 to 30g DDW) and glucose solution (0.2 to 4g dextrose and 5 to 20 g DDW). By adding CuSO 4 Or copper acetate (1 to 6 g) was dissolved in DDW (20 to 60 g) to prepare a Cu source solution. The two solutions were mixed with each other and aged at room temperature for 14 hours. The gel was transferred to a 50 ml polytetrafluoroethylene lined reaction kettle, which was heated under steady conditions at 200°C to 250°C for 1 to 5 days. Then, ...

Description

[0001] Cross References to Related Applications [0002] This application is a continuation of the International Application No. PCT / KR2012 / 003248 filed on April 26, 2012, the entire contents of which are incorporated herein by reference. technical field [0003] Embodiments described herein generally pertain to novel copper silicate molecular sieves and methods for preparing the molecular sieves that enable the synthesis of copper silicate molecular sieves in high yields. Background technique [0004] The synthesis and characterization of one-dimensional (1D) semiconducting quantum-confined materials is of great importance due to their potential for building blocks of nanoscale electronic devices and other novel applications. Among known 1D semiconductor materials, molecular wires or quantum wires are the thinnest 1D quantum confinement materials, but there are few examples of such quantum wires. Recently, the inventors of the present invention have studied titanate (=TiO ...
