Turn Waste Golden Tide into Treasure: Bio-Adsorbent Synthesis for CO Capture with KFeO as Catalytic Oxidative Activator.

Converting (SH)-a harmful marine stranding that can cause golden tide-to highly porous bio-adsorbent material (via one-step catalytic oxidative pyrolysis with KFeO) can be a strategically useful method for obtaining low-cost materials suitable for CO capture. In this manuscript, the behavior of different mass ratios of KFeO/SH precursor acting on the surface physicochemical properties of carbon materials are reported. The results suggest that specific surface area and total pore volume first increased to the mass ratio of KFeO/carbon precursor, then decreased.

Enhanced Assembling of N-and-K-Riched Macroalgae as Carbon Adsorbent for CO Capture with Ni(NO)/KOH as Co-Catalysts.

Porous-activated carbons have drawn great attention due to their important role in CO capture. Ni(NO)/KOH, as co-catalysts under different temperatures, were studied to obtain porous graphitized carbon from feedstock. The results indicated that the properties of the porous graphitized carbon generated at 850 °C were greatly enhanced, showing a large specific surface area of 1486.
