Study of molar properties of GO after doping with transition metals for photodegradation of fluorescent dyes

Abstract

We synthesize and characterise graphene oxide doped with transition metal ions, and calculate the Mark–Houwink constants, determining methylene blue degradation efficiency.

LSNR:GO template for BSA interaction, photo and sonocatalytic reductions of fluorescent dyes in aqueous solutions

“…To obtain pure GtO, ice-cold water was mixed with a reaction mixture on adding 3 mL H 2 O 2 (30%) and stirred for 10 min to cease a reaction. 5 The resultant product was centrifuged at 8000 rpm for 10 min and washed with Milli-Q water, HCl and absolute alcohol until the supernatant attained pH 7. AgNO 3 and BaCl 2 tests ensured complete removal of NaCl and Na 2 SO 4 after 5 washings, and a brownish sediment was coagulated with petroleum ether.…”

“…These were refluxed at 55℃ @ 650 rpm in oil bath for 12ℎ to attain 𝑅𝑇. To a pure 𝐺𝑡𝑂, an ice-cold water was mixed with a reaction mixture on adding 3mL 𝐻 2 𝑂 2 (30%) and stirred for 10min to cease a reaction 4 . The resultant product was centrifuged @8000 rpm for 10min and washed with Milli-Q water, 𝐻𝐶𝑙 and absolute alcohol till a supernatant attains 𝑝𝐻 7.…”

“…Therefore, synthesizing new photocatalyzing nanomaterials for reducing wastewater effluents in sunlight is a biological and natural need to recycle. The PCR split a wastewater to H2 and O2 gases, and also recycle its fluorescent effluents and transitional metals to collect the usable water 4 . Since decades, a focus has been made for developing photocatalyzing metallic organic framework, metallic biocomplexes, bimetallic complexes using transitional metals reported in previous study 4,5 .…”

“…And also, for solving a most tedious and hazardous chemical processes. The 𝐿𝑆𝑁𝑅 and 𝐿𝐺𝑇 acted as renewable energy storage systems and dopants with pharmaceuticals, digital inks, textiles, integrated circuits (𝐼𝐶𝑠), and heat sensors 4,5 . PCPs, 𝑃𝐶𝑅, and 𝑆𝐶𝑅 predict their structural abilities to photocatalyze and solubilize the biomolecules as BSA.…”
