In this study, graphene oxide (GO) nanosheets have been used for the adsorption of methyl green, a cationic dye from aqueous solution. GO consist single layered graphite structure decorated with number oxygen containing functionalities such as carboxyl, epoxy, ketone, and hydroxyl groups which impart negative charge density to it in solution at wide range pH. Thus, can be predicted good adsorbent material species. The green onto has carried out different experimental conditions kinetics,...
Over the past decade, nanosized metal oxides, metals, and bimetallic particles have been actively researched as enzyme mimetic nanomaterials. However, common issues with individual nanoparticles (NPs) are stabilization, reproducibility, blocking of active sites by surfactants. These problems promote further studies composite materials, where NPs spread on supports, such graphene derivatives or dichalcogenide nanosheets. Another promising type support for is few-layered hexagonal boron...
The greater advantages and wide applications of zero-dimensional nanodots inspire researchers to develop new materials. Therefore, novel borophene quantum dots (QDs) were prepared by a hydrothermal liquid exfoliation technique using water medium. QDs proved be highly stable in medium for more than 120 days. synthesized revealed intrinsic peroxidase mimetic activity two chromogenic substrates, 3,3′,5,5′-tetramethylbenzidine (TMB) 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic...
The adsorption behavior of the methyl blue dye molecule, a mutagenic agent onto graphene oxide (GO) and reduced (rGO) nanosheets, has been investigated at different pH values, times, temperatures, also in presence ions like Na+, Ca2+, Mg2+, SO42–. A green solution chemistry approach adopted for synthesis rGO where ascorbic acid is used as reducing under ultrasonication. kinetic investigation revealed that GO/rGO nanosheets–water interface follows linear pseudo second-order kinetics....
