Data_Sheet_1_Biomass Juncus Derived Nitrogen-Doped Porous Carbon Materials for Supercapacitor and Oxygen Reduction Reaction.pdf

Juncus is a perennial herb aquatic plant found worldwide, with high reproductive ability in warm regions. It has three-dimensional hierarchical porous triangular networks structures composited of tubular fibers. Here, juncus derived nitrogen-doped porous carbon (NDPC) was prepared by mixing juncus and ZnCl2 through one-step pyrolysis and activation which is a low-cost, simple, and environmentally friendly method. The NDPC had hierarchical porous structures and a high specific surface area and was applied for supercapacitor and oxygen reduction reaction (ORR). The resulted NDPC-3-800 was prepared by mixing juncus with ZnCl2 at a mass ratio of 1:3 and then carbonized at 800°C, it was used as electrode material of a supercapacitor. The supercapacitor exhibited excellent specific capacitance of 290.5 F g−1 and 175.0 F g−1 in alkaline electrolyte at the current densities of 0.5 A g−1 and 50 A g−1, respectively. The supercapacitor showed good cycle stability, and the capacitance was maintained at 94.5% after 10,000 cycles. The NDPC-5-800 was prepared by mixing juncus with ZnCl2 at a mass ratio of 1:5 and then carbonized at 800°C. It exhibited outstanding ORR catalytic activity and stability attributing to their high specific surface area and abundant actives sites. The juncus can derive various materials for application in different fields.</p

Underwater Superoleophobic and Salt-Tolerant Sodium Alginate/<i>N</i>‑Succinyl Chitosan Composite Aerogel for Highly Efficient Oil–Water Separation

Materials for oil–water separation under harsh conditions that exhibit high separation efficiency, salt tolerance, and the capability of high-speed separation and reusability are in great demand. In this study, we introduce a series of sodium alginate (SA)/N-succinyl chitosan (NSCS) composite aerogels with outstanding mechanical strength, robust salt tolerance, and high oil–water separation efficiency. These aerogels were well designed and prepared through a combination of a freeze-drying method, ionic cross-linking, and chemical cross-linking. Due to their remarkable mechanical performance and good flexibility, the composite aerogels could achieve oil–water separation under various harsh conditions. The separation efficiency reached 99% owing to the outstanding underwater superoleophobicity and high-porosity structure of the aerogel. More importantly, the aerogels could preserve their high separation efficiency and underwater superoleophobicity after being soaked in a saturated NaCl solution for 30 days or after 30 separation cycles, which suggested their favorable stability under high-salinity conditions. These results indicated that SA/NSCS aerogels were qualified materials for oil–water separation, which gives us hope for their application in oil–water separation under harsh conditions
