Photocatalytic degradation of methyl orange and Congo red using C,N,S-tridoped SnO2 nanoparticles
Authors
Abstract:
In this study, the photocatalytic degradation of methyl orange and Congo red dye was investigated inaqueous solution using C,N,S-tridoped SnO2 nanoparticles as a nano photocatalyst. The degradationwas carried out under different conditions including the photocatalyst amount, initial concentrationand pH of the solution. The results indicated that the degradation of methyl orange and Congo redwas strongly influenced by these parameters. The best conditions for the degradation of methylorange and Congo red were obtained. The optimum value of photocatalyst amount used was 0.4 g/L.It was found that the photodegradation efficiency increase with increasing the initial concentration ofmethyl orange and Congo red. The optimum pH of the system used is 6.5.

ZnO and 2% Fe doped ZnO photocatalytic nanomaterials were successfully synthesized by successive ionic layer adsorption and the reaction (SILAR) method. The characterizations of these nanomaterials were carried out using XRD, SEM and EDX techniques. XRD study shows that the samples have a hexagonal wurtzite crystal structure, size of which is in the range 21-23 nm. SEM shows nanoflakes or nano ...
full textPhotocatalytic degradation of methyl red dye
Introduction Most dyes used in the pigmentation of textiles, paper, leather, ceramics, cosmetics, inks and food-processing products are derived from azo dyes, which are characterised by the presence of one or more azo groups (-N=N-) in their structure. Approximately 15% of the dyes produced worldwide are lost within waste water during synthesis and processing. This waste represents a great haza...
