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 … Continue reading →

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 … Continue reading →

With the development of an all electric autonomous cargo ship by Kongsberg and Yara International, is the need for synthetic CO2-based fuels diminishing? In this op-ed, Geoff discusses the state of electrification and the continued need for CO2-based fuels. The … Continue reading →

Congratulations to Jia on her two recently published papers! Her review published in ChemSocRev covers the broad field of how defects in metal oxides play a role in the heterogeneous catalytic hydrogenation of CO2. Her paper published in Avanced Science … Continue reading →

In this op-ed, Geoff outlines the roadmap to achieving CO2 utilization on a gigaton scale, detailing four missions: to utilize atmospheric CO2, recycle CO2 from combustion sources, prevent CO2 being released into the atmosphere, and boost CO2 sinks on the … Continue reading →

Despite hydrogen having the largest known gravimetric energy storage capacity (33kWh/kg), its storage requires prohibitively low temperatures or high pressures. In this op-ed, Geoff describes the use of liquid organic hydrogen carriers to effectively access hydrogen hydrogen storage. The full … Continue reading →

Transportation is well known to generate a large fraction of the world’s anthropogenic CO2, which consequently produces negative consequences for future transportation, specifically aviation. In this op-ed, Geoff highlights the effect of climate change on aviation, including intensification of clear … Continue reading →

In this op-ed, Geoff describes the four performance indicators of CO2 reduction technologies: product selectivity, material stability, mass conversion, and solar-to-fuel energy efficiency. Alone, these indicators may be misleading, but Geoff highlights a report by Steinfeld’s group which reported all … Continue reading →

Geoff’s latest op-ed details the history of methanol synthesis from the pyrolysis of wood in ancient egypt to the current state of the art Cu/ZnO and Cu/ZrO2 catalysts. The full article can be read here or on the Advanced Science … Continue reading →

Thermally splitting of water typically requires temperatures around 1500°C. In this op-ed, Geoff discusses the case of Cu@TiO2 as a photothermally driven water splitting catalyst operating under 1 sun illumination and under 150°C. The key to this approach is a … Continue reading →
