“…3 Therefore, there is an urgent demand for the mitigation of CO 2 emissions, resulting in extensive efforts worldwide to develop novel and inexpensive strategies for CO 2 adsorption. 4 For this purpose, various porous solid-based adsorbents for CO 2 capture such as metal-organic frameworks (MOFs), 5 aminesilica, 6 zeolites, 7 porous polymers, 8 metal oxides, 9 aminecontaining materials, 10 and carbonaceous materials 7 have been developed with suboptimal CO 2 adsorption performance mainly originating from their low N-doped content. Nitrogen functional groups have been found to increase the electron donor properties of carbon by affecting its spin density, resulting in the enhanced isosteric heat of adsorption and chemisorption of adsorbents even at high temperatures.…”

We report a unique naturally derived activated carbon with optimally incorporated nitrogen functional groups and ultra-microporous structure to enable high CO 2 adsorption capacity. The coprocessing of biomass (Citrus aurantium waste leaves) and microalgae (Spirulina) as the N-doping agent was investigated by probing the parameter space (biomass/microalgae weight ratio, reaction temperature, and reaction time) of hydrothermal carbonization and activation process (via the ZnCl 2 /CO 2 activation) to generate hydrochars and activated carbons, respectively, with tunable nitrogen content and pore sizes. The central composite-based design of the experiment was applied to optimize the parameters of the prehydrothermal carbonization procedure resulting in the fabrication of N-enriched carbonaceous products with the highest possible mass yield and nitrogen content. The resulting hydrochars and activated carbon samples were characterized using elemental analysis, X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, field emission scanning electron microscopy, and Brunauer−Emmett−Teller surface area analysis. We observe that while N-doping and the activation process can individually enhance the CO 2 adsorption capacity to some extent, it is the combined effect of the two processes that synergistically work to greatly increase the adsorption capacity of the N-doped activated carbon by an amount which is more than the sum of individual contributions. We analyze the origins of this synergy with both physical and chemical characterization techniques. The resulting naturally derived activated carbon demonstrates one of the highest CO 2 adsorption capacities (8.43 mmol/g) with rapid adsorption kinetics and good selectivity and reusability.

“…Meanwhile, hyperbranched polymers (HBPs) have a unique physical structure and chemical characteristics, such as the nearly three-dimensional spherical molecular shape with a large number of reactive terminal groups, the absence of molecular chain entanglement, many branching points caused high chemical reactivity, and strong chemical resistance . These advantages make HBPs a good material for the applications as coatings, , biomedical materials, − adsorbents, − antimicrobial agents, , and adhesives. , Therefore, using the unique properties of HBPs in the modification of GE adhesives would provide the adhesive with better performance.…”

Gelatin (GE), a nontoxic and degradable biomass resource, is a multistage hydrolysate of collagen. However, its application in adhesives was always limited by its brittleness and poor water resistance. In order to overcome this shortcoming, herein, epoxy-terminated hyperbranched polymers (EHPAEs) were first selected as a cross-linking agent to modify the GE extracted from leather solid wastes to prepare a series of novel GE-based environmentally friendly adhesives. First, EHPAE was synthesized and the structure of the hyperbranched polymer was measured by Fourier-transform infrared and 1H NMR spectroscopy. Then, the adhesives were obtained using the EHPAE to modify GE. The adhesion effect of the prepared adhesives was evaluated by tensile and T-peel tests on the surface of leather, in order to determine whether this adhesive achieved the quality requirements for footwear and bags. The result indicated that EHPAE-modified GE-based adhesives had higher solid content, superior adhesion ability, and water resistance. Moreover, the bonding layer of this adhesive was tough and ductile, while the bonding layers of the recently reported GE-based adhesives were brittle. This adhesive also surpassed the recently reported GE-based adhesives in terms of water resistance and adhesion performance.
