Ordered Mesoporous

A highly ordered mesoporous carbon@iron disulfide (CMK-5@FeS2) composite was prepared via an in-situ impregnation and sulfurization method. The CMK-5 matrix with excellent conductivity and high surface area not only formed a continuous conductive network to improve the performance of the CMK-5@FeS2 composite, but also provided sufficient space to buffer the volume changes during cycling. The CMK-5@FeS2 cell exhibited excellent electrochemical performance. After 80 cycles, the CMK-5@FeS2 cell showed the discharge capacities of 650 and 380 mAh g–1 at 2 C and 5 C, respectively. The excellent results show that CMK-5 with unique mesoporous structure can contribute to accelerating ion transfer in the electrode due to the easy accessibility of the electrolyte, which implies CMK-5@FeS2 composite could be a promising cathode active material for rechargeable lithium ion (Li-ion) batteries.

Adsorption Of Co

Highly ordered mesoporous carbon (CMK-3) was fabricated for the adsorption of cobalt from aqueous solutions. With the high surface area of1112.7m2/g and pore size of 17.2 nm, its abundant mesopores were benefit for providing channels for liquid propagate. In order to improve the adsorption properties,CMK-3 was modified by hydroxylation and amination. Fourier transform infrared (FTIR) spectroscopy can be seen that the amino group was successfully grafted onto the CMK-3 with highly ordered mesoporous structure. The functionalized ordered mesoporous carbon (CMK-3-EDA) ,CMK-3 and CMK-3-OX were used as absents for the adsorption of Co (II) from aqueous solution. The results showed that CMK-3-EDA were more twice effective in adsorption of Co (II) compared to CMK-3, which indicated that CMK-3-EDA had great potential for the adsorption of Co (II).

In nature, kaolin clay is referred to a readily available cheap source of silicon and used in various fields such as the paper, ceramic, paint, plastic, rubber, and cracking catalyst industries. This paper introduces utilization of natural kaolin clay for a new application. In particular, the kaolin clay is used as a new raw material for synthesis of ordered mesoporous carbon (OMC) materials, which serve as electrode active materials for supercapacitors. Kaoline used in the present work is originated from Yen Bai province (Vietnam). After subjected several steps of the treatment process, silica present in the kaolin clay is converted to sodium silicate and used directly as a source of silicon for the synthesis process of mesoporous porous silica (SBA-15). The synthesized SBA-15 mesoporous silicas exhibit rod-like nanostructure with the specific area of 432.7 m2 g-1 and the mean pore size of 7-8 nm. Subsequently, SBA-15 silica serves as hard template for preparation of OMCs by using nanocasting method. The OMCs carbonized at different temperatures in the absence and presence of boric acid reveal highly ordered mesoporous structure with the highest specific area of 1039.2 m2 g-1 and the mean pore size ranging from 6 to 7 nm. As used as electrode active material in 6 M KOH aqueous solution, the resultant OMCs exhibit excellent capacitive performance with a specific capacitance higher than 80 F g-1 at a scan rate of 5 mV s-1. The obtained results show that, in addition to the high specific area, the electrical conductivity also plays an important role in enhancing energy storage ability of the OMC electrodes. At the same carbonization temperature, the high surface area plays crucial role. However, at the higher carbonization temperatures, effect of the electrical conductivity of the materials prevails over the high surface area. This study illustrates highly application feasibility of Vietnam natural kaolin clay as available and cheap raw material source for synthesis of electrode active materials with the high supercapacitive performance for electrochemical double layer capacitors.

Acetalization Reaction

Sulfonated ordered mesoporous carbon (SOMC) has been used as a new catalytic material in heterogeneous reactions for it can replace many conventional homogeneous acid catalysts. At present, it was obtained mainly through sulfonating the surface of mesoporous carbon by post-processing method, which contained relatively complex process and rigorous condition. In this work, SOMC was prepared directly via pre-processing method. The structure and morphology of SOMC were characterized by means of FT-IR, XRD, TEM and BET, the catalytic performance was investigated by the acetalization reaction between benzaldehyde and n-butyl alcohol as a model reaction. The result showed that SOMC has excellent high surface area and uniform mesostructure when the mole ratio of phenolic resin: sulfuric acid: F127 was 1: 2: 0.0238 and carbonization temperature was 600°C. In the acetalization reaction, the yield of acetal of using SOMC material as catalyst was 87.1%, much higher than that of using HY zeolite, which shows that the SOMC has excellent catalytic property in the catalytic reaction of acetalization.
