Controlling the Active Center of Gold Nanoreactors by Mediating the Metal-Polymer Interaction

Shah V., Malardier-Jugroot C., Jugroot M., Malardier-Jugroot C., Royal Military College of Canada, CA

Nanomaterials have gained large interest from the scientific community due to the fact that materials at nanoscale exhibit unique electronic, magnetic and optical properties when compared to the bulk. The main advantage associated with nanostructures [...]

Biomimetic Nanoreactors via in situ Synthesis of Atomically-Thin Gold Sheets and Platinum Nanoclusters

McTaggart M., Malardier-Jugroot C., Jugroot M., Malardier-Jugroot C., Royal Military College of Canada, CA

We present the synthesis and activity of broadly stable polymer-metal nanoreactors capable of confinement-enhanced catalysis. Poly(styrene-alt-maleic acid), SMA, is known to self-assemble in water into highly organized supramolecular nanostructures containing confined polar and non-polar reaction [...]

Synthesis and characterization of nanoreactors within polymeric nanotemplates

McTaggart M., Groves M., Malardier-Jugroot C., Jugroot M., Malardier-Jugroot C., Royal Military College of Canada, CA

The paper will present a novel method for the synthesis of metal nanoclusters with diameters < 3nm within an amphiphilic nanotube template without the use of a reducing agent. This environmentally friendly synthesis occurs at [...]

Comparing the Effect of 2nd Row Dopants on the Carbon Support to improve Pt Catalytic Activity and Durability

Groves M.N., Chan A.S.W., Malardier-Jugroot C., Jugroot M., Malardier-Jugroot C., Royal Military College of Canada, CA

This work outlines improvements to the Pt catalyst durability and activity by modifying the carbon catalyst support for use in the proton exchange membrane fuel cell. Computational methods have shown that nitrogen and boron dopants [...]

Characterizing the Oxygen Reduction Reaction for the Proton Exchange Fuel Cell with with Novel Nanotechnology-based Catalyst Supports

Groves M.N., Chan A.S.W., Malardier-Jugroot C., Jugroot M., Malardier-Jugroot C., Royal Military College of Canada, CA

The oxygen reduction reaction (ORR) on the cathode of the proton exchange membrane fuel cell is still inefficient. This work will focus on the activity of the catalyst when varying the catalyst support. In the [...]

Predicting PEMFC Pt Catalyst Durability using DFT

Groves M.N., Chan A., Malardier-Jugroot C., Jugroot M., Malardier-Jugroot C., Royal Military College of Canada, CA

DFT calculations using B3LYP/Lanl2DZ on nitrogen doped graphene and single walled carbon nanotube structures are evaluated using Gaussian03 to measure the binding energy between its surface and a Pt atom. This is to characterize the [...]
