Photo- and Electrochemical Valorization of Carbon Dioxide Using Earth-Abundant Molecular Catalysts.

The dramatic increase in anthropogenic carbon dioxide emissions in recent decades has forced us to look for alternative carbon-neutral processes for the production of energy vectors and commodity chemicals. Photo- and electrochemical reduction of CO are appealing strategies for the storage of sustainable and intermittent energies in the form of chemical bonds of synthetic fuels and value-added molecules. In these approaches, carbon dioxide is converted to products such as CO, HCOOH and MeOH through proton-coupled electron transfer reactions.

Renewable Methane Generation from Carbon Dioxide and Sunlight.

The direct approach: Methane is a potential key player in the world's transition to a more sustainable energy future. The direct conversion of carbon dioxide into methane is highly desirable to lower the concentration of CO in the atmosphere and also to store renewable energy. This Highlight describes the first homogeneous system for the light-driven conversion of CO into CH .
