Journal ArticleDOI
Tunable (violet to green) emission by high-yield graphene quantum dots and exploiting its unique properties towards sun-light-driven photocatalysis and supercapacitor electrode materials
Sumeet Kumar,Animesh K. Ojha,Animesh K. Ojha,Bilal Ahmed,Ashok Kumar,Jayanta Das,Arnulf Materny +6 more
TL;DR: In this article, the feasibility of the production of mono-dispersed spherical GQDs (∼4nm) based on a treatment solely with ammonia solution as both, reducing and stabilizing agent was investigated.
Journal ArticleDOI
Shape induced (spherical, sheets and rods) optical and magnetic properties of CdS nanostructures with enhanced photocatalytic activity for photodegradation of methylene blue dye under ultra-violet irradiation
TL;DR: In this paper, the effect of shape on optical and magnetic properties of CdS nanostructures was studied by monitoring the photodegradation of methylene blue (MB) dye under the UV irradiation of wavelength 365nm.
Journal ArticleDOI
Cadmium oxide nanoparticles grown in situ on reduced graphene oxide for enhanced photocatalytic degradation of methylene blue dye under ultraviolet irradiation
TL;DR: The synthesized samples showed enhanced ferromagnetism (FM) at room temperature, which may be attributed to the short range magnetic interaction of magnetic moments of CdO NPs and spin units present on the rGO sheets.
Journal ArticleDOI
Facile and controlled synthesis of aligned WO3 nanorods and nanosheets as an efficient photocatalyst material.
TL;DR: The synthesized WO3 nanostructures showed improved photocatalytic activity for the photodegradation of MB dye, and the enhanced photocatallytic activity of WO1 nanosheets compared to WO2 nanorods for photodegrading of methylene blue (MB) dye could be due to the shape of the nanostructure of W O3.
Journal ArticleDOI
Enhanced photocatalytic activity of rGO-CeO2 nanocomposites driven by sunlight
Sumeet Kumar,Ashok Kumar +1 more
TL;DR: In this article, the structural, morphological and optical features of the synthesized rGO-CeO 2 nanocomposites were systematically investigated and correlated in order to authenticate the improved photocatalytic performance.
