Facile hydrothermal synthesis of TiO2 nanospindles-reduced graphene oxide composite with a enhanced photocatalytic activity

Purification of organic pollutant by the novel ternary complex

“…Compared to GO, both complete vanish of (001) and the appearance at 24.5°(002) peak in rGO-TNT composites suggests successful conversion from GO to rGO. Narrow and sharp peaks confirm that all the samples are crystalline [11][12][13][14]. A remarkable shift from 48.1°to 48.4°is probably caused by the connection between TNT and rGO.…”

“…5, we can find that rGO can widen light absorption to visible light. This phenomenon hints that rGO could expand light absorption from UV to visible light because of the surface modification of rGO [13][14][15]18]. Furthermore, rGO improves the baseline of 1 % rGO-TNT sample, which can be explained by the fact that the light across the sample was prevented by graphene sheets.…”

“…No characteristic peaks of impurities could been detected means its major crystal planes are well-structured (Fig. 4) [10][11][12][13]. We can also see a (Fig.…”

Photocatalytic, sonocatalytic, and photosonocatalytic of Fe3O4/CuO/ZnO nanocomposites with addition of 2 different types of carbon

“…6 and 7, we could also see with the incorporation of NGP or graphene an increase in catalytic activity was obtained, as shown the incorporation of graphene has the highest catalytic activity than FCZ/NGP and FCZ. The increase in decolorization activity with the incorporation of NGP or graphene may be due to the interesting supportive properties of graphene, one of which graphene could act as an electron trap that could hinder recombination of electron and hole pairs [21]. However, the difference in increment of decolorization activity between NGP and graphene addition may be due to different types of the layer and specific surface area.…”

Synthesis and catalytic performance of hierarchical TiO 2 hollow sphere/reduced graphene oxide hybrid nanostructures

“…The combinations of TiO 2 and RGO have recently gained increased research interest, since the composites present improved photocatalytic behaviors [19e29]. For example, Fan et al prepared TiO 2 nanospindle/RGO composites via a hydrothermal method, and the products give an impressive photocatalytic enhancement over pure TiO 2 [25]. Anderson et al reported that TiO 2 /thermally RGO composites showed superior photocatalytic activity for phenol degradation [27].…”
