CMK-3 over the CAC, adsorption capacity, adsorption rate, and equilibrium time is short, is a good adsorbent, while of the mesoporous carbon CMK-3 for phenol adsorption thermodynamics and kinetics. CMK-3 adsorption of phenol used Langmuir and Freundlich isotherm to describe the correlation is good, but more in line with Freundlich empirical formula. were used to simulate first-order reaction and second-order reaction model examined the adsorption kinetics and the calculation of these dynamics model rate constants. analog second-order reaction model and experimental data a good correlation between the respectively calculated thermodynamic parameters ΔG0, ΔS0 and ΔH0, results show that, CMK-3 for phenol adsorption process is endothermic and spontaneous .
Mesoporous carbon is a new type of non-silicon-based mesoporous materials with large specific surface area (up to 2500m2 / g) and pore volume (up to 2.25cm3 / g), is expected to catalyst, hydrogen storage materials, electrode materials and other aspects of important applications, so are people’s attention. In addition, mesoporous materials obtained by the double-layer capacitance charge storage material above the metal oxide particles assembled electric capacity, far higher than commercially available metal oxide double-layer capacitors.
And pure mesoporous silica materials, mesoporous carbon materials exhibit unique properties, high specific surface area, high porosity; pore size adjustable within a certain range; mesoporous shapes, hole wall composition, structure and nature of the adjustable; by optimizing the synthesis conditions can be high thermal stability and hydrothermal stability; synthesis is simple, easy to operate, no physiological toxicity. It is still in its attraction of fuel cells, molecular sieve, adsorption, catalysis, electrochemistry and other areas of potential applications. In recent years, mesoporous materials science has become an international cross-chemistry, physics, materials, biology and other disciplines cross one of the hot areas of research, development of materials science have become an important milestone.
Mesoporous material as a photocatalyst for the treatment of environmental contaminants is one of the hot research in recent years. For example, mesoporous TiO2 Bi Nami TiO2 (P25) has a higher photocatalytic activity, because the mesoporous structure with high surface area to improve contact with organic molecules, an increase of surface adsorbed water and hydroxyl, water and hydroxyl groups with the catalyst surface can be excited by light the reaction of hydroxyl radical hole, and hydroxyl radical degradation of organic matter is a strong oxidant, can put a lot of biodegradable organic matter is oxidized to CO2 and water and other minerals. In addition, the ordered mesoporous materials for selective doping can improve the optical activity of visible light photocatalytic degradation of organic waste to increase the efficiency.
Now widely used in domestic water chlorine disinfection process though killed all bacteria, but had chloroform, carbon tetrachloride, monochloroacetic acid and a series of toxic organic compounds, its serious “three letter” effects (cancer, teratogenic, mutagenic) has attracted international scientific and medical community’s attention. Through the pores of mesoporous materials received on the inner wall of the school γ-chloropropyl triethoxysilane, has been functionalized mesoporous CPS-HMS, the functional mesoporous molecular sieves to remove traces of chloroform in water results are obvious, the removal rate of up to 97%. After the treated water chloroform concentrations below the national standard, even lower than the drinking water standards.
