Summary: Graphene nanomaterials have been commercialized and disseminated into surface waters, but their photodegradation in natural aquatic environments is minimal and slow. This study evaluated the photodegradation of graphene oxide and partially reduced graphene oxide in Columbia River Water, finding that both direct and indirect photolysis occur simultaneously. However, the concentrations of photosensitizers in surface water are not sufficient to initiate degradation of graphene oxide. Overall, graphene nanomaterials show minimal phototransformation in natural surface water.

Summary: Constructing high performance electrocatalysts, such as the single atomic catalyst of Fe-N-4 moiety doping periphery with S (Fe-NSC), can effectively enhance lithium polysulfides (LiPSs) adsorption and facilitate sulfur conversion, improving the energy density and cycle life of rechargeable lithium-sulfur (Li-S) batteries. By modifying the graphene oxide supported Fe-NSC catalyst (Fe-NSC@GO) to the commercial separator, Li-S cells exhibit high discharge capacity and excellent cyclability, with 1156 mAh g(-1) at 1 C rate and a low capacity decay of only 0.022% per cycle over 1000 cycles. This work provides new insights into structural tuning of electrocatalysts to improve the electrochemical performance of Li-S batteries.

Summary: Aqueous polysulfide/iodide redox flow battery shows great potential in grid-scale energy storage due to its high solubility of active materials, flexible designability, and low cost. However, the poor electrochemical activity of polysulfide hinders its commercial application. In this study, self-supported NiCo2S4 nanoneedle arrays on carbon paper were synthesized, which possess excellent adsorption and electrocatalytic properties for polysulfide and promote the electrocatalytic process of iodide, achieving bifunctional catalysis. The redox flow battery with NiCo2S4@CP electrode exhibits a peak power density of 82.4 mW cm(-2) and ultra-long cycle stability, operating stably for over 3400 hours at a current density of 10 mA cm(-2).

Summary: This study investigates the CO2 reduction to methanol catalyzed by CoPc through in situ X-ray absorption spectroscopy characterization. CoPc dispersed on CNT surfaces enables fast electron transfer and multi-electron CO2 reduction. The labile CO intermediate on the active site requires a high local concentration to compete with CO2 and promote methanol production. The bridging aza-N atoms of the Pc macrocycle are critical components of the CoPc active site.
