報(bào)告簡(jiǎn)介：

In the future we will have to extensively rely on sustainable energy that comes in the form of electricity, and we therefore must rethink our entire chemical production which today is based on fossil resources. One of the most challenging processes is the activation of molecular nitrogen, which is essential for life, as it constitutes a part of all amino acids and nucleic acid. Sustainable energy is produced de-centrally and ammonia is used de-centrally as fertilizer, therefore imagine if we could do like Nature and synthesize ammonia at ambient conditions. We have recently demonstrated that an electrochemical lithium mediated process can indeed activate Nitrogen and synthesize ammonia at ambient conditions. We have subsequently followed up on this new insight and based on models improved the Faradaic efficiency by oscillating the potential, optimizing the Oxygen content in the Nitrogen gas, and by synthesizing high area electrodes. Very recently we have designed a fuel cell type cell which is scalable, and which can operate continuously using hydrogen as the proton source with both Li or Ca. This is the first step towards making this a viable de-centralized process, although outstanding questions concerning the energy efficiency will be discussed.
