Embodiment 1

[0076] 1mmol of Co(NO 3 ) 2 ·6H 2 O and 1 mmol phenylphosphonic acid were added to 60 mL of N,N-dimethylformamide (DMF), stirred magnetically for 30 min at room temperature, transferred to a 100 mL polytetrafluoroethylene-lined reactor, and placed at 110 °C In a special oven, keep warm for 24 hours, cool down naturally, vacuum filter, wash three times with deionized water and alcohol alternately, and dry at 60°C for 12 hours to obtain a purple-red powder that is cobalt phenylphosphonate (CoPPA).

Embodiment 2

[0078] 1mmol of Ni(NO 3 ) 2 ·6H 2 O and 1 mmol phenylphosphonic acid were added to 60 mL of N,N-dimethylformamide (DMF), stirred magnetically for 30 min at room temperature, transferred to a 100 mL polytetrafluoroethylene-lined reactor, and placed at 110 °C In an oven, keep warm for 24 hours, cool down naturally, vacuum filter, wash 3 times alternately with deionized water and alcohol, and dry at 60°C for 12 hours to obtain a yellow-green powder that is nickel phenylphosphonate (NiPPA).

Embodiment 3

[0080] Get the cobalt phenylphosphonate (CoPPA) sample that 50mg embodiment 1 prepares and the nickel phenylphosphonate (NiPPA) sample that embodiment 2 prepares and add respectively to two 99mL deionized water and 1mL triethanolamine (TEOA) are housed In the reactor, ultrasonic 10min, put the two reactors into the photocatalytic hydrogen production reaction system, pass the cooling circulating water, maintain the system temperature at 15 ℃, vacuumize, and then add 254nm ultraviolet lamp to irradiate, set the chromatographic sampling time to 1h .

Abstract

The invention provides phenyl phosphonate with photocatalytic activity as well as a preparation method and application thereof, and belongs to the technical field of photocatalytic materials. The preparation method for phenyl phosphonate comprises the following steps that metal salt and phenylphosphonic acid are dissolved in an organic solvent, and a solvothermal method is adopted to prepare phenyl phosphonate. According to phenyl phosphonate as well as the preparation method and application thereof, a phenyl phosphonate photocatalytic material is synthesized by adopting the solvothermal method for the first time and is applied to photocatalytic hydrogen production and carbon dioxide reduction; and meanwhile, the raw materials are low in price, easy to obtain, environmentally-friendly, safe and pollution-free, the preparation method is simple and easy to operate, and the values of industrial production and practical application are achieved.

Description

technical field [0001] The invention belongs to the technical field of photocatalytic materials, and in particular relates to a phenylphosphonate with photocatalytic activity and a preparation method and application thereof. Background technique [0002] With social development and technological progress, energy and environmental issues have become increasingly prominent and have drawn attention from all over the world. Photocatalytic technology uses clean and efficient solar energy to split water to generate renewable hydrogen energy, degrade organic pollutants, and reduce CO 2 etc., become an effective way to solve energy shortage and environmental pollution. Therefore, people are constantly looking for efficient, cheap, easy-to-obtain, and environmentally friendly photocatalytic materials. [0003] Due to the properties of both organic phosphonic acid and inorganic metal ions, organic phosphonates have received extensive attention in photocatalysis and other fields. Me...
