To prepare high-performance activated carbon paper, this study investigates the changes in performance and structure of Poly(p-phenylene terephthalamide) (PPTA) paper under CO2 activation, ZnCl2 activation, H3PO4 activation, and NaOH activation conditions. The research reveals that carbon paper after CO2 activation has a certain tensile strength (0.36 MPa), while chemically activated carbon paper lacks tensile strength. Incorporating 15% carbon fiber (CF) into PPTA paper increases the tensile stress (1.26 MPa) and tensile strain (4.18%) of the activated carbon paper. NaOH-activated carbon paper has the highest specific surface area (1321.6 m2/g), the most disordered carbon structure (ID/IG = 1.22), the lowest carbon yield (23.9%), and a pore rate 4.16% higher than that of CO2-activated samples. The activated carbon paper prepared by ZnCl2 activation has the highest content of C = N bonds, with the nitrogen content of pyridine increasing by 31.8% compared to CO2 activation. This indicates that ZnCl2 protects the N elements in PPTA paper during the activation process, preventing their decomposition during carbonization.

Incorporating nanostructures into porous materials is becoming more widely acknowledged for its great importance. This strategy has attracted much interest because of its exceptional features imparted on the catalysts, offering enormous promise in accelerating the reduction of nitrophenols. In recent years, various nanostructures have been embedded to a wide range of porous materials, such as carbon, silica, metal-organic frameworks, and other inorganic materials. These porous frameworks possess unique physical and chemical characteristics, making them well-suited for catalytic applications. This thorough review begins by explaining the mechanism of nitrophenol reduction, exploring several nanostructures based on noble metals that are commonly used for catalytic reduction. Following that, a systematic description and comparison of nitrophenols catalytic reduction using various nanostructures on porous templates such as carbon-based, silica-based, zeolite-based, polymer-based, and metal-organic frameworks (MOF) were explained. In addition, this paper also examines several functional materials to enhance the catalytic reduction of nitrophenols.

The synthesized adsorbents were characterized by different technquies and the results confirmed the presence of zero-valent iron (ZVI) nanoparticles and other iron oxides as products of the carbothermal reduction.

The performance was evaluated in the removal process of toxic Cr(VI) in an aqueous medium, and the optimum conditions of the process were reported. The removal process was dependant of solution pH where best results was achieved at pH = 2. Complete removal of chromium was achieved in less than 5 min by MMC700. The results were better fitted with pseudo-second-order kinetics and followed the Freundlich model isotherm. The maximum adsorption capacity was found to be 265.25 mg/g for MMC700, suggesting its application as an efficient, low-cost, and easily separable adsorbent for the toxic Cr(VI) removal process.
