Closing the Carbon Cycle to Stop Climate Change

Reducing the CO2 levels in the Earth’s atmosphere is key to stopping further environmental degradation. CO2 conversion to methane (green fuel) using renewable hydrogen is considered as one of the best options with great potential for simultaneously resolving energy and environmental challenges. Unfortunately, this process needs an expensive metal or complex organometallics and most of them suffer from instability and poor selectivity towards methane. In this work, using the defect engineering approach, researchers develop defected nano-silica, which convert CO2 to methane at the significant rates, scales, and stabilities.
