Gold nanodendrities on graphene oxide nanosheets for oxygen reduction reaction

Bioreduction of Precious Metals by Microorganism: Efficient Gold@N‐Doped Carbon Electrocatalysts for the Hydrogen Evolution Reaction

“…The ORR performance of Au@NC was better than those of reported Au-based ORR catalysts, such as Au cluster/graphene (À0.08 V vs. Ag/AgCl, n % 3.6), [8a] and gold nanodendrites on graphene oxide nanosheets (half-wave potential of + 0.61 V vs. RHE, n = 3.7). [16] The aforementioned results reveal a simple and straightforward strategy for recovering precious metals using a microorganism to fabricate valuable electrocatalysts with HER and ORR functionality. The remarkable catalytic activity of Au@NC may be attributed to the following factors.…”

Chemical profiling and quantification of Gua-Lou-Gui-Zhi decoction by high performance liquid chromatography/quadrupole-time-of-flight mass spectrometry and ultra-performance liquid chromatography/triple quadrupole mass spectrometry

“…High performance liquid chromatography-ultraviolet detection (HPLC-UV) and gas chromatography-mass spectrometry have been reported for the quality control of GLGZD [16][17][18][19]. These methods made significant contributions to the quality control of GLGZD, however, they were inclined to determine the limited compounds, and had some shortcomings such as long analysis time and poor LOQs.…”

Biomolecule-assisted synthesis of porous PtPd alloyed nanoflowers supported on reduced graphene oxide with highly electrocatalytic performance for ethanol oxidation and oxygen reduction

“…Additionally, as demonstrated by the C 1s XPS spectrum (Fig. 4D), the intensity of C-C bond is much stronger than those of C-O, C¼O, and O-C¼O bonds, [18] substantially confirming the formation of RGO [35].…”

“…S3, ESI), indicating the essentialroleofRGOforthe synthesisofuniformandwell-distributed PtPd NFs (Fig.1). It is attributed to the fact that reactive oxygen atoms on GO surfaces form the steric inhibition and prevent PtPd NFs from further aggregation [35,40]. The dispersing effects of GO can not only decrease the usage of metals, but also improve the conductivity of the nanocomposites to enhance the catalytic property [13].…”
