The materials chemistry research group encourages top-rank post doctoral fellows, both national and international, to apply for the elite Banting and Vanier Canada Graduate Scholarships to support their work in our group.
The applications can be found on the Banting and Vanier websites.
We also encourage Marie-Curie and Alexander von Humbolt fellows as well as other top rank international graduate and post-graduate scholars holding research fellowships to apply for positions in our group.
Well done Ab on your solar fuels paper published in Advanced Energy Materials, January 2018, where you demonstrate a highly efficient ambient temperature Solar Sabatier process whereby CO2 photomethanation is catalyzed by nanostructured RuO2 on a silicon photonic crystal support at the remarkable rate of 4.4 mmol gcat-1h-1. This exceptional photomethanation rate is due to the large surface area coupled with the unique light-trapping and broadband optical absorption properties of the photonic crystal support.

Zheng-Min Wang, Wendong Wang and Geoffrey Ozin have discovered a synthetic pathway to a sandwich-type nanocomposite of reduced graphene oxide and periodic mesoporous silica in which mesochannels of silica vertically align with respect to the graphene layers with tunable mesochannel depth and size. Deep insight into the formation mode of this novel class of materials obtains from a high photon flux small angle X-ray scattering technique and zeta potential-based solution chemistry, Advanced Functional Materials 2017, DOI: 10.1002/adfm.201704066

Congratulations Annabelle, Wei and Chenxi as well as Ab, Yuchan and Ziqi on your Advanced Sustainable Systems paper entitled Tailoring CO2 Reduction with Doped Silicon Nanocrystals!!
In this work, silicon nanocrystals doped with varying combinations of phosphorous and boron were investigated for the heterogeneous photoreduction of CO2. The observed trends in stability and activity open new pathways towards the development of sustainable CO2 conversion catalysts.

With the push towards renewable power generation and electrification, energy storage will likely require improvements to facilitate the increased electricity generation. In this op-ed, Prof. Ozin describes the potential for CO2 derived hydrocarbons as one of several energy storage techniques of the future.

Different CO2 utilization technologies are currently of interest as it is unlikely for just one technology to be the solution for climate change, but rather the combination of many sustainable technologies. In this op-ed, Geoff introduces the concept of Li-CO2 batteries as a utilization of CO2. The battery is proposed to reversibly cycle between Li + CO2 and Li2CO3 + C for charging and discharging.
