Professor Ozin asks the question; do we want war or peace with CO2?

Solar Refinery: Can we have our carbon cake and eat it too?

Scheme Futuristic ‘solar refinery’ for making fuels and chemicals from CO2, H2O and sunlight, Reproduced from A general framework for the assessment of solar fuel technologies, Energy & Environmental Science, DOI:  (or Ref XX) with permission of The Royal Society of Chemistry.

Professor Ozin explores the feasability of a solar refinery for making fuels and chemicals from CO2, H2O and sunlight.

What can we do if the IPCC’s response to climate change – assessment of risk, vulnerability, mitigation, adaptation and cost – fails to deliver?

Is semiconductor photocatalysis photochemical or thermochemical or both? (and do we care?)

Professor Ozin addresses a fundamental concern in the field of photocatalysis.

Real or Artifact: CO2 Photo-Catalysis versus Carbon Contamination

Leaf Mimic - Fact or Fiction. Graphic illustration courtesy of Chenxi Qian.

Geoff Ozin asks if carbon dioxide capture and utilization, a potential solution to the CO2 problem, is feasible with today’s photo-conversion technology.

A Fossil Fuel Free World
