A simple and facile method is described for the in situ synthesis of graphene oxide-Ag nanoplates (GO-AgNPs) hybrid structure and then served as sacrificial templates for producing graphene oxide-Au nanorings (GO-AuNRs) by galvanic replacement taken place on the GO surface. The catalytic activity of the resulting hybrid nanomaterial has been investigated for the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) with sodium borohydride (NaBH4). The results showed that the rate constant of GO-AuNRs nanomaterials was 0.205[Formula: see text]min[Formula: see text] and the samples showed significant enhancement in catalytic activity.

Fischer Tropsch Synthesis

AbstractOne key goal of heterogeneous catalysis study is to understand the correlation between the catalyst structure and its corresponding catalytic activity. In this review, we focus on recent strategies to synthesize well-defined Fischer-Tropsch synthesis (FTS) nanostructured catalysts and their catalytic performance in FTS. The development of those promising catalysts highlights the potentials of nanostructured materials to unravel the complex and dynamic reaction mechanism, particularly under the in situ reaction conditions. The crucial factors associated with the catalyst compositions and structures and their effects on the FTS activities are discussed with an emphasis on the role of theoretical modeling and experimental results.
