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.
Austria’s Museum of Applied Arts in Vienna opening in December will showcase a diorama of Prof. Ozin’s vision of a closed carbon cycle.

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.
The article can be read on the Advanced Sustainable Systems website.
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.

In order to minimize the effects of climate change, net greenhouse gas (GHG) emissions must be reduced to zero. In this op-ed, Geoff details how GHG-emitting technologies are being displaced by more environmentally friendly technologies, but also touches on some GHG-emitting technologies that will be more difficult to replace.

In the inaugural issue of Joule, Geoff provided a commentary on Prof. Steinfeld’s work on CO2 reduction. Their current photo-thermal reactor design implementing a CeO2 catalyst is described with insight into the chemistry of how the originally multistep process has been reduced into a single step process.

In this op-ed, Geoff makes a case for CO2 sourced synthetic fuels despite the growing electrification trend in transportation. Key points in the production-use-end life cycle of each path is highlighted for considering whether the production and use of CO2 sourced fuels can be more efficient than renewable energy driven electrification.

In celebration of Geoff’s 74th birthday, a vignette of his past 50 years of scientific contributions is featured. Geoff’s work on nanochemistry began with with the controlled nucleation and growth of ‘naked’ metal atoms in cryogenic conditions and has since expanded towards self-assembly of materials over all length scales including: bio-inspired nanomaterials, mesoporous silicas and organosilicas, photonic crystals, silicon nanocrystals, and many more.
