摘要

With regard to CO2 usage for the sustainable production of value-added chemicals, this work provides a fast pyrolysis process for the first time that can be scaled up in directly capturing CO2 to produce N-doped carbon foam (NCF) as a functional nanomaterial. Flammable alkaline solutions of hydrazine hydrate serves as CO2 adsorbent, fuel as well as nitrogen source for the NCFs, and magnesium powders are involved into the reaction to provide complex metal ion and also energy for the self-propagating high-temperature combustion pyrolysis. The prepared NCFs exhibit efficient electrochemistry performance toward lithium-ion battery and oxygen reduction reaction benefiting from the well-formed foam structure with hierarchical pores, in situ nitrogen doping and high specific surface area. More importantly, this approach introduce a general solution system that can further integrate various additives dissolved homogeneously, thus greatly increasing process controllability and product selectivity for the thermochemical conversion of CO2.
