Description of the technology
The subject of the offer is an innovative, environmentally friendly method for obtaining of CMK-3 carbon replica, which may be a material useful in various catalytic and sorption processes as well as electrochemical applications. The method has a high potential for industrial application, and its use can significantly improve the production of high-ordered carbon materials with high surface area.
In recent years the synthesis of CMK-n type carbon replicas has been the subject of intense research focused on obtaining of carbon materials with surface properties typical for activated carbon and highly ordered pore system. The main advantages of CMK-n materials, being the key to industrial applications, are favorable pore diameters, a highly developed specific surface area and highly ordered arrangement of the mesochannel system. Furthermore, the properties of carbon replica can be precisely controlled by a choice of proper conditions of synthesis and thermal treatment. Thus, the research is concentrated on optimization of the conditions of the carbon replicas synthesis that nowadays is a complicated, multi-stage process, requiring use of expensive and toxic reagents and solvents. Those disadvantages preclude the possibility of application of the previously proposed methods in an industrial practice. The proposed method of the CMK-3 synthesis is based on an alternative path.
Main advantages of its use
- A higher structural arrangement of the resultant replica in comparison to materials obtained by the methods previously reported in the literature;
- Higher content of surface oxygen-containing groups responsible for the high catalytic activity and sorption capacity.
- The major advantages of the proposed synthesis route are following: minimizing of the number of synthesis steps, elimination of toxic reagents and solvents, simplification of the equipment required for the synthesis as well as reduction of time and energy consumption.Besides the economic and environmental benefits the proposed method has other advantages, namely:
- The possible application of the invention is easier and cheaper manufacturing the CMK-3 carbon replica.The CMK-3 carbon replica synthesized according to the invented method was tested as a catalyst in the process of oxidative dehydrogenation of ethylbenzene to styrene.
