Organic Solvent Based Synthesis of Gold Nanoparticle - Semiconducting 2H-MoS2 Hybrid Nanosheets
Abhijit Ganguly, Olga Trovato, Shanmughasundaram Duraisamy +4
The development of simple, versatile strategies for the synthesis of gold nanoparticles (AuNPs) on semiconducting transition metal dichalcogenides (TMDC) layers is of increasing sc…
Sensitive Chronocoulometric Detection of miRNA at Screen-printed Electrodes modified by Gold decorated MoS2 Nanosheets
Abhijt Ganguly, John Benson, Pagona Papakonstantinou
Here a new chronocoulometric sensor, based on semiconducting 2H MoS2 nanosheets decorated with a controlled density of monodispersed small gold nanoparticles, was fabricated via el…
The Effects of Exfoliation, Organic Solvents and Anodic Activation on Catalytic Hydrogen Evolution Reaction of Tungsten Disulfide
Wanglian Liu, John Benson, Craig Dawson +5
The rational design of transition metal dichalcogenide electrocatalysts for efficiently catalyzing hydrogen evolution reaction (HER) is believed to lead to the generation of a rene…
Electrocatalytic Hydrogen Evolution Reaction on Edges of a Few Layer Molybdenum Disulfide Nanodots
John Benson, Meixian Li, Shuangbao Wang +2
The design and development of inexpensive highly efficient electrocatalysts for hydrogen production, underpins several emerging clean-energy technologies. In this work, for the fir…
Tuning the catalytic activity of graphene nanosheets for oxygen reduction reaction via size and thickness reduction
John Benson, Qian Xu, Peng Wang +5
Currently, the fundamental factors that control the oxygen reduction reaction (ORR) activity of graphene itself, in particular the dependence of the ORR activity on the number of e…
Nitrogen-Functionalized Graphene Nanoflakes (GNFs:N): Tunable Photoluminescence and Electronic Structures
J. W. Chiou, Sekhar C. Ray, S. I. Peng +22
This study investigates the strong photoluminescence (PL) and X-ray excited optical luminescence observed in nitrogen-functionalized 2D graphene nanoflakes (GNFs:N), which arise fr…
