Crowd oil not crude oil

Congratulations to authors Prof. Roland Dittmeyer, Michael Klumpp, Paul Kant, and Prof. Geoffrey Ozin on the release of their Nature Communications article, “Crowd oil not crude oil”. The delocalized nature of climate change poses a major challenge to mitigation efforts. The authors propose retrofitting air conditioning units to convert water and carbon dioxide into fuel. The users would collect the synthetically-made oil for their personal use, or to redistribute within their community, as to encourage decentralized CO2 conversion and energy democratization.

Advanced Science News: “Spamming Science”

The internet has had profound effects on virtually all aspects of society. It has revolutionized virtually every aspect of our lives, from the ways in which we engage and communicate, to our shopping and entertainment habits, and to our media and politics. But what of the effect of the internet age on academia? As one of the earliest adopters of email communication, academics have witnessed the many ways in which the internet has shifted the nature of scientific collaborations, publishing processes, and research patterns. Have we, however, reached a point where electronic communication has become more problematic than beneficial to academic research?

Energy & Environmental Science Cover Page!

Congratulations to authors Mireille Ghoussoub, Meikun Xia, Dr. Paul Duchesne, and Prof. Dvira Segal, as well as cover artist and alumnus, Dr. Chenxi Qian, for having their recently published review article featured on the cover of Energy and Environmental Science. Photothermal catalysis is an emerging sub-discipline of heterogeneous catalysis that exploits broad absorption of the solar spectrum to stimulate a combination of thermochemical and photochemical processes, which contribute synergistically to driving catalytic reactions. It is proving an effective and promising strategy for converting CO2 to synthetic fuels.

Putting a Spin on a Carbon Photocatalysis Spin-off

Chemicals and fuels derived from CO2 and enabled by solar power have taken the research world by storm over the past decade. However, CO2-derived fuel technologies, as promising as they may appear, are still subject to the harsh economic realities of chemical engineering. Is it possible to simultaneously achieve high photonic efficiencies all whilst adhering to the logic of economies of scale? Two new start-ups, The Solistra Corporation and Dimensional Energy, have taken on this challenge and are paving the way towards a future driven by solar fuel technology

Congratulations to Athan Tountas and Co-authors on your Solar Methanol Advanced Science Paper!

“Towards Solar Methanol: Past, Present, and Future” provides a comprehensive overview of how value-added products, notably methanol, can be produced affordably and sustainably from greenhouse gases. Harnessing light in the form of solar energy can assist is the production process in some capacity through various strategies, such as solar-thermochemical, photochemical, and photovoltaic-electrochemical. Commercially-ready technologies are compared via technoeconomic analysis, and the scalability of solar reactors is also discussed in the context of light-incorporating catalyst architectures and designs. Finally, the review offers perspective on the viability of the most promising solar methanol strategy to be applied at a global scale.

Catalytic CO2 Reduction by Palladium Decorated Silicon Hydride Nanosheets

Congratulations to Wei, Chenxi, Govind, and Co-Authors on their New Years Eve Nature Catalysis publication in which they report on their discovery of how to make Silicon, the second most abundant element on earth, behave catalytically in the gas-phase heterogeneous hydrogenation of CO2 to CO, known as the Reverse Water Gas Shift Reaction.

Congratulations Mireille, Paul, Meikun on your Energy and Environmental Chemistry publication “Principles of Photothermal Gas-Phase Heterogeneous CO2 Catalysis”

Photothermal catalysis is an emerging sub-discipline of heterogeneous catalysis that exploits broad absorption of the solar spectrum to stimulate a combination of thermochemical and photochemical processes, which contribute synergistically to driving catalytic reactions. In particular, it is proving an effective and promising strategy for converting CO2 to synthetic fuels. See full article at Energy & Environmental Science.

The Agnotology of Carbon Dioxide

In 1995, Robert Proctor of Stanford University coined the term, “Agnotology”, refering to the study of how and why we do not know things as a means of addressing the rapid dissemination of misleading, confusing, frightening and false information. Although early works in this field were focused on the understanding the ignorance around smoking and cancer risk, Agnotogy is highly relevant to the current rhetoric surrounding climate change. The reality is that CO2 emissions due to human activity are contributing to climate change and that to limit the warming from pre-industrial levels to 1.5 °C these emissions must be reduced to zero by 2050. Unfortunately, however, denial or acceptance of global warming often stems from selectivity in the search for evidence and political leaning. See full paper at Advanced Science News.

Congratulations to Dr. O’Brien et al. on their paper “Enhanced photothermal reduction of gaseous CO2 over silicon photonic crystal supported ruthenium at ambient temperature”

Solar-driven CO2 hydrogenation can provide a renewable source of fuels and reduce greenhouse gas emissions at industrial scale. The paper investigates the light-driven Sabatier reaction over Ru films sputtered onto silica opal (Ru/SiO2) and inverted silicon opal photonic crystal (Ru/i-Si-o) supports. Under ambient temperature conditions, photomethanation rates over both the Ru/SiO2 and Ru/i-Si-o catalysts were shown to increase significantly with increasing light intensity, and rates as large as 2.8 mmol g−1 h−1 are achieved over the Ru/i-Si-o catalyst. Furthermore, the quantum efficiency of the photomethanation reaction was found to be almost three times larger when measured over the Ru/i-Si-o catalyst as compared to the Ru/SiO2 catalyst. DFT analysis indicate that charged Ru surfaces can destabilize adsorbed CO2 molecules and adsorb and dissociate H such that it can readily react with CO2, thereby accelerating the Sabatier reaction.

CO2 Conversion and Corrosion: Mind the Gap

The community of scientists and engineers dedicated to the development of synthetic fuels made from CO2 is large and growing. From catalytic synthesis to reactor design, these researchers work on devising strategies to yield the most energy efficient and cost-effective CO2 conversion technologies. There exists, however, another community of experts also dedicated to working on CO2, albeit from a very different perspective: these are the scientists and engineers dedicated to the capture, purification, transportation and distribution of CO2 for either storage or enhanced oil recovery purposes. Their attention is largely focused on the important, and yet often forgotten corrosive nature of CO2 on processing equipment, containers, and pipelines made of carbon steel. Given the current trend, these seemingly disparate fields would greatly benefit by overcoming the CO2 communications gap, which appears to exist between scientists and engineers working on these problems.
