Highly Dispersed Ag Nanocrystals Anchored on N-Doped Holey Carbon Aerogel as High-Mass-Loading Electrode for Cl - Capture in Hybrid Capacitive Deionization

Nanostructured Faradaic materials show extraordinary promise for capacitive deionization (CDI) toward the relief of global freshwater scarcity. But at present, there exist at least two shortages for the development of CDI electrode materials. In laboratory studies, evaluating their desalination performance is usually based on low mass loadings (80% atom-economic utilization of Ag, as well as superior Cl -capture performances. This work provides a general guideline on how to estimate the optimal mass loadings for constructing highly active CDI electrodes in the future.
