New Materials Discovery: Machine-Enhanced Human Creativity

In this article, published in Chem, a sister journal to Cell, Geoffrey Ozin and Todd Siler, a long time practicing chemist and artist, ask whether machine learning will ever be creative enough to match the innate ingenuity of humans at discovering and synthesizing an entirely new class of materials.

Congratulations Young Li

Congratulations Young Li on your paper in ACS Applied Materials and Interfaces (DOI: 10.1021/acsami.8b04982) in which a novel palladium-tungsten oxide hetero-nanostructure Pd@HyWO3-x is shown to function as a high performance photocatalyst for enabling the gas-phase reduction of CO2 to CO at an impressive rate of 3.0 mmol gcat-1 h-1. A photochemical pathway operates via bandgap excitation of HyWO3-x along with photothermal contributions arising from non-radiative electron relaxation in Pd nanocrystals and the plasmon band of HyWO3-x. Kinetic analysis revealed a decrease in the activation energy for CO formation in the dark compared to the light with kinetics being more CO2 dependent in the dark to more H2 dependent in the light. Operando diffuse reflectance infrared Fourier transform spectroscopy measurements provided valuable insight into the surface chemistry responsible for the conversion of CO2 to CO formation. The Pd@HyWO3-x system provides a blueprint for rationally designing and optimizing catalysts that enable gas-phase photothermal reduction of CO2.

Congratulations Lu Wang, Meikun Xia, Hong Wang, Kefeng Huang, and Chenxi Qian on your Perspective “Greening Ammonia toward the Solar Ammonia Refinery”

The century-old Haber-Bosch process for the production of ammonia from N2 and H2 is an energy demanding and greenhouse gas intensive, high temperature and high pressure, fossil powered process. A contemporary challenge is to replace this unsustainable process by a sustainable one that produces ammonia from N2 and H2O, powered by solar electricity, solar heat or solar photons.

In this Perspective, we present an overview of current research activity and technology development in this area together with a high level energy analysis shown in the graphic of the different ways being explored to achieve the lofty goal of a ‘solar ammonia refinery’.

U of T Solar Fuels Group Awarded Major Funding for Greenhouse Gas Project

Professor Geoff Ozin and the Solar Fuels Team at the University of Toronto have been awarded close to $1 million from the Low Carbon Innovation Fund (LCIF) to translate their greenhouse gas research to scale.

Reza Moridi, Ontario’s Minister of Research, Innovation and Science made the announcement at the Ontario Centres of Excellence Discovery conference on May 1. The project proposes a technology capable of recycling CO2, either from the atmosphere or from concentrated industrial sources, into value-added chemicals and fuels. Ontario’s Low Carbon Innovation Fund will help researchers, entrepreneurs and companies create and bring to market innovative low-carbon technologies. Moridi says that LCIF initiatives such as this, “will help us fight climate change while preparing industries to thrive in a competitive, low-carbon economy.” Ozin is excited to begin work on the Greenhouse Gases to Fuels project, commenting “working with the Low Carbon Innovation Fund, we intend to demonstrate that our G2F technology is an effective approach to making Ontario both environmentally sustainable and economically successful.”

Congratulations of Michael Ertl and Co-workers!

Quite surprisingly, the synthetic version of a naturally occurring iron mineral named after a Nobel laureate (Mössbauerite), which has been previously studied by geologists and soil scientists, was found to be a promising ‘iron only’ electrocatalyst for the oxygen evolution reaction (OER). In a four-way collaboration between the Universities of Bayreuth, Bochum, Munich, and Toronto, the electrocatalytic performance of synthetic mössbauerite is demonstrated to be competitive with the best-known ‘iron only’ electrocatalysts. Significantly, the structure of Mössbauerite offers plenty of opportunities for compositional modifications in the quest for a champion earth-abundant, low-cost, non-toxic electrocatalyst

Congratulations, Lu, Mireille, and Co-Authors, on your Solar Methanol Paper in Joule!

The current fashion for synthesizing methanol continues to be the high pressure and high temperature heterogeneous catalytic conversion of synthesis gas (CO-H2) using alumina supported nanostructured copper-zinc oxide as the catalyst and fossil fuel to power the process. It is an energy intensive process with a large CO2 greenhouse gas footprint and a deleterious effect on the climate. Thus, it would be highly desirable to produce methanol in a sustainable way and use CO2 as feedstock and solar energy to drive the synthesis. Solar technologies that facilitate the efficient conversion of CO2 and H2 into methanol offer a sustainable path to the production of renewable fuels. Furthermore, since about 30% of all known chemicals come from methanol, the production of solar methanol appears to be a “greener” strategy for the chemical and petrochemical industries. In this breakthrough report in Joule, we present a “solar methanol maker”, a rod-shaped In2O3-x(OH)y nanocrystal superstructure, that can efficiently hydrogenate CO2 to methanol at atmospheric pressure with a methanol selectivity for more than 50%. The remarkable production rate of 0.06 mmol gcat-1h-1 and excellent long-term stability of this catalyst in solar methanol synthesis makes it an interesting candidate for converting CO2 to methanol at an industrial scale in a CO2 refinery.
