To maximize the ion adsorption capacity with fast electrosorption, hierarchical multi-pore structures have been suggested in energy conversion and desalination technologies. However, it is hard to synthesize hierarchical structure via successive chemical process or template methods. In this article, we developed carbon composite electrode including mesoporous and microporous carbon via facile method for both high surface area and fast electrosorption. We observed that introducing mesoporous carbon to microporous carbon can improve the ad-sorption kinetics by enhancing wettability for water transport and simplifying ion transfer pathway. Finally, GNPAC 1:1 composite electrode showed the highest average salt adsorption rate, attributed from better ad-sorption kinetics and increased effective area for adsorption in fast flow rate of electrolyte compared to pristine microporous and mesoporous carbon electrode.
