This research intended to report amine-functionalized multiwall carbon nanotubes (MWCNTs) prepared by a simple method for efficient and rapid removal of Reactive Yellow 2 (RY2) from water. EDS analysis showed that the N content increased from 0 to 2.42% and from 2.42 to 8.66% after modification by APTES and PEI, respectively. BET analysis displayed that the specific surface area, average pore size, and total pore volume were reduced from 405.22 to 176.16 m2/g, 39.67 to 6.30 nm, and 4.02 to 0.28 cm3/g, respectively. These results proved that the PEI/APTES-MWCNTs were successfully prepared. pH edge experiment indicated that pH 2 was optimal for RY2 removal. At pH 2 and 25 °C, the time required for adsorption equilibrium was 10, 15, and 180 min at initial concentrations of 50, 100, and 200 mg/L, respectively; and the maximum RY2 uptake calculated by the Langmuir model was 714.29 mg/g. Thermodynamic studies revealed that the adsorption process was spontaneous and endothermic. 0-0.1 mol/L of NaCl showed negligible effect on RY2 removal by PEI/APTES-MWCNTs. Five adsorption/desorption cycles confirmed the good reusability of PEI/APTES-MWCNTs in RY2 removal. Overall, the PEI/APTES-MWCNTs are a potential and efficient adsorbent for reactive dye wastewater treatment.

“…Meanwhile, the g‐C 3 N 4 is composed of the N‐bridged tri‐s‐triazine repeating units, and formed π‐conjugated graphitic plane 24 . Although the layered structure of g‐C 3 N 4 was resembled as graphite, the electrical conductivity of g‐C 3 N 4 was still relatively low 25,26 . Therefore, it is a promising approach to improve the electrical conductivity by partially reversely substituting the nitrogen atom with low‐electronegativity carbon atoms and then inhibiting the recombination of photogenerated charge carriers of g‐C 3 N 4 .…”

Since the traditional g-C 3 N 4 photocatalyst was severely affected by low charge transfer rates and light absorption capacity, which inevitably limited its application in environmental pollution treatment. Herein, mixing the 2,4,6-triaminopyrimidine (TAP) doped melamine and biomass porous carbon (BPC), the TAP-BPC/CN composite with desirable conductivity was synthesized by one step thermal condensation. That is, the carbon atom of TAP was used to partially replace the nitrogen atom of tri-s-triazine structure of g-C 3 N 4 , and decreased the interlayer distance of graphite lamellar structure, then improved the electrical conductivity of the materials and suppressed the recombination of photogenerated carriers. At the same time, the incorporation of BPC also contributed to increase the active sites of the material and enhance the separation efficiency of photogenerated carriers. Furthermore, the formation of p-n homojunction in TAP-BPC/CN built the construction of an internal electric field at the interface, which induced the band bending and improved charge separation and transfer effectively. As a result, the sample of TAP-BPC/ CN exhibited an excellent adsorption and photocatalytic activities in the degradation of oxytetracycline (OTC). This research provides a new strategy for efficient photocatalysts with high absorption and photocatalysis in the antibiotic wastewater treatment.
