Atomically Dispersed Cobalt Sites on Graphene as Efficient Periodate Activators for Selective Organic Pollutant Degradation

Environmental Science & Technology · 2021-03-17 · 295 citations

Pollutant degradation via periodate (IO4–)-based advanced oxidation processes (AOPs) provides an economical, energy-efficient way for sustainable pollution control. Although single-atomic metal activation (SMA) can be exploited to optimize the pollution degradation process and understand the associated mechanisms governing IO4–-based AOPs, studies on this topic are rare. Herein, we demonstrated the first instance of using SMA for IO4– analysis by employing atomically dispersed Co active sites su…

Novel Positively Charged Metal-Coordinated Nanofiltration Membrane for Lithium Recovery

ACS Applied Materials & Interfaces · 2021-04-02 · 150 citations

Nanofiltration (NF) with high water flux and precise separation performance with high Li+/Mg2+ selectivity is ideal for lithium brine recovery. However, conventional polyamide-based commercial NF membranes are ineffective in lithium recovery processes due to their undesired Li+/Mg2+ selectivity. In addition, they are constrained by the water permeance selectivity trade-off, which means that a highly permeable membrane often has lower selectivity. In this study, we developed a novel nonpolyamide…
