Embodiment 1
[0029] (1) Disperse 1.5mmol melamine in 150mL acetonitrile, stir for 30min, immerse in cotton fabric (5cm*5cm), then gradually add 0.75mmol melamine and stir for 30min, then irradiate in a 150W high-pressure mercury lamp (ultraviolet lamp) After 12 hours, wash with acetonitrile several times and dry at 60°C for 8 hours to obtain cotton fabric / polynitrogen material;
[0030] (2) Dissolve 0.8mL of pyrrole monomer and 0.2g of bismuth tungstate in 120mL of hydrochloric acid (0.8mol / L), put into the above-mentioned cotton fabric / polynitrogen material to make it adsorb pyrrole monomer and bismuth tungstate for 1h, and then Keep the temperature of the mixed solution at about 0°C under ice bath, then slowly add 50mL ferric chloride / hydrochloric acid solution (100g / L) dropwise, the fabric can be observed to turn from white to black, and finally washed several times with deionized water and placed in Dry at 60°C for 4 hours to obtain a highly efficient and recyclable catalytic material ...
Embodiment 2
[0032] (1) Disperse 2.25mmol melamine in 175mL acetonitrile, stir for 30min, immerse in cotton fabric (5cm*5cm), then gradually add 0.75mmol melamine and stir for 45min, then irradiate in a 150W high-pressure mercury lamp (ultraviolet lamp) After 18 hours, wash with acetonitrile several times and dry at 70°C for 10 hours to obtain cotton fabric / polynitrogen material;
[0033] (2) Then, dissolve 1.2mL pyrrole monomer and 0.3g bismuth tungstate in 160mL hydrochloric acid (1mol / L), put the above cotton fabric / polynitrogen material to make it adsorb pyrrole monomer and bismuth tungstate for 1.5h, and then Keep the temperature of the mixture at about 2.5°C under an ice bath, then slowly add 50mL of ferric chloride / hydrochloric acid solution (150g / L) dropwise, the fabric can be observed to turn from white to black, and finally washed several times with deionized water and placed in Dry at 60°C for 4 hours to obtain a highly efficient and recyclable catalytic material of cotton fabri...
Embodiment 3
[0035] (1) Disperse 3mmol melamine in 200mL acetonitrile, stir for 30min, immerse in cotton fabric (5cm*5cm), then gradually add 0.75mmol melamine and stir for 60min, then irradiate with 150W high-pressure mercury lamp (ultraviolet lamp) for 24h After that, wash several times with acetonitrile and dry at 80°C for 12 hours to obtain cotton fabric / polynitrogen material;
[0036](2) Dissolve 1.6mL of pyrrole monomer and 0.4g of bismuth tungstate in 200mL of hydrochloric acid (1.2mol / L), put into the above-mentioned cotton fabric / polynitrogen material to make it adsorb pyrrole monomer and bismuth tungstate for 2 hours, and then Keep the temperature of the mixed solution at about 5°C under an ice bath, then slowly add 50mL of ferric chloride / hydrochloric acid solution (200g / L) dropwise, the fabric can be observed to turn from white to black, and finally washed several times with deionized water and placed in Dry at 60°C for 4 hours to obtain a highly efficient and recyclable cataly...
