Waste-biochar catalyst converts mixed CO/CO₂ electrochemically
Summary
Catalyst cost is a key challenge in the conversion of waste CO₂ into useful products. This technology uses a sustainable catalyst platform to convert carbon-containing waste streams into value-added chemicals. The approach has demonstrated promising laboratory-scale performance and may offer a lower-cost and more resource-efficient alternative to conventional conversion technologies. The technology has potential carbon abatement benefits by converting waste carbon streams into useful chemical products while reducing process complexity and resource requirements.
What makes this novel compared to best-in-class technology?
Most CO₂ conversion catalysts rely on expensive precious metals. This catalyst is made instead from horticulture waste. It also works directly on a mixture of carbon monoxide and CO₂, so the two gases do not need to be separated first.
