Facile in situ synthesis of silver nanoparticles on boron nitride nanosheets with enhanced catalytic performance

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.

Geobacillus Thermocatenulatus

A novel heterogeneous enzyme-palladium (Pd) (0) nanoparticles (PdNPs) bionanohybrid has been synthesized by an efficient, green, and straightforward methodology. A designed Geobacillus thermocatenulatus lipase (GTL) variant genetically and then chemically modified by the introduction of a tailor-made cysteine-containing complementary peptide- was used as the stabilizing and reducing agent for the in situ formation of ultra-small PdNPs nanoparticles embedded on the protein structure. This bionanohybrid was an excellent catalyst in the synthesis of trans-ethyl cinnamate by Heck reaction at 65 °C. It showed the best catalytic performance in dimethylformamide (DMF) containing 10–25% of water as a solvent but was also able to catalyze the reaction in pure DMF or with a higher amount of water as co-solvent. The recyclability and stability were excellent, maintaining more than 90% of catalytic activity after five cycles of use.
