Embodiment 1

[0030](1) Preparation of rod-shaped cadmium sulfide CdS NRs

[0031] 20.25mmol CdCl 2 2.5H 2 O (4.62g) and 60.75mmol CH 4 N 2 S (4.62g) was added into a 100mL autoclave containing 60mL of ethylenediamine and sealed, and the autoclave was transferred to 160°C for a reaction time of 48h. .Wash the obtained yellow powder with water and ethanol to remove impurities, and centrifugally filter and dry to obtain the product;

[0032] (2) Preparation of NTP

[0033] a: Place triptene (1.25g, 5mmol) in a three-necked flask, add concentrated HNO 3 50 mL, the mixture was heated and stirred at 75° C. for 24 h, and condensed under reflux. The reaction solution was a brown solution, which was cooled to room temperature, then poured into H 2 O (1000 mL) was stirred for 30 min. The precipitate was collected, washed with distilled water, and dried in air. The crude product was purified with dichloromethane / petroleum ether (1:1) as the eluent to give the white solid products 2,6,14-tri...

Description

technical field [0001] The invention belongs to the technical field of nanomaterial preparation and application, relates to a preparation method of a rod-shaped cadmium sulfide CdS NRs / triplene polymer NTP novel composite photocatalyst, and also belongs to the field of organic chemical synthesis. Background technique [0002] The development and synthesis of microporous materials with regular pore structure with channel size below 2nm has been one of the hotspots in the field of materials science research. As emerging microporous materials, metal-organic frameworks (MOFs) and organic microporous polymers are widely used in gas adsorption and separation, catalysis and sensing due to their large specific surface area, synthetic diversity and easy introduction of functional groups. The field attracts attention. Triptycene has a unique three-dimensional rigid structure, which is composed of three benzene rings bridged by carbon atoms, and the angle between each benzene ring is ...
