From Venus to vehicle exhausts.
electric vehicles could delay the climate benefits of this transition.
To make the best use of existing petrol and diesel-burning vehicles – and the carbon that was invested in creating them – drivers and manufacturers can reduce the emissions of a family of compounds called nitrogen oxides, which are, through better treatment of exhaust fumes. This way, the communities most blighted by air pollution can at least be protected before harmful vehicle emissions are finally eradicated.
My research team is developing a new generation of catalytic converters – the devices fitted to exhaust pipes to reduce the release of toxic gases. Inspired by chemistry observed on the surface of extremely hot planets such as Venus, we haveThe Sun’s light destroys carbon dioxide in the atmospheres of planets, producing carbon monoxide . Not fast enough to avert climate change, but enough that atmospheres like Venus should contain far more CO than we observe there.
Our group studies the effects of meteoric material in atmospheres. An iron silicate powder we made that replicates this dust the conversion of CO to CO₂. This is what the first catalytic converters in cars were designed to do since CO is a toxic gas.That got us thinking about whether this material could help with other problems, such as nitrogen oxide pollution, which
