50 Years of Materials Research and Still Searching

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.

Never Say Never

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.

Congratulations two Jia!!

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 summarized her work on controlling the selectivity of CO and CH4 production from CO2 reduction by tuning the size of Pd nanoparticles supported on Nb2O5.

Gigaton CO2 Conversion

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 ocean and land.
A modular CO2 refinery developed by Ineratec is highlighted, enabling Lego like assembly of small to industrial scale CO2 refineries

H2 Storage in Liquid Organic Hydrogen Carriers

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.

In Flight and Fight

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 air turbulence, rising sea levels around coastal airports, and more frequent storm surges.

Drop-in Solar Fuels from CO2 and H2O: Performance Indicators

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 four values in a solar reactor utilizing ceria catalyst.

Turning Down the Heat

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 two step reduction and oxidation cycle in a low pO2 environment.

CO2 Desalination

Concerns over the world’s supply of fresh water has been steadily growing and if not addressed, is expected to cost 6% of the world’s GDP by 2050. In this op-ed, Geoff describes how brine saturated with CO2 will crystallize as CO2@H2O clathrate hydrates separately from the salt at high pressure and low temperature.

This approach tackles two problems simultaneously as a way to utilize CO2 and desalinate water.
