Carbon dioxide, a major greenhouse gas, can be used as a source of carbon. Conversion of CO2 into organic compounds has been studied intensively. For example, ethane catalytic dehydrogenation [Equation (1)] offers an attractive route for converting CO2. Firstly, the coke-formation problem, particularly troublesome in the steam-cracking industry, can be solved by treating the coke with CO2 to generate CO over the catalyst. In addition, CO2 can act as a medium for supplying heat to the endothermic dehydrogenation reaction. 4] Furthermore, the products from Equation (1), C2H4 and CO, are precursors for olefin/CO copolymerization reactions. By varying the feedstock ratio (C2H6/CO2) in the reaction, different ratios of the products (C2H4/CO) can easily be obtained for the specific copolymerization process. Hence, the dehydrogenation of ethane in the presence of CO2 is an ideal feedstock for any process involving ethylene carbonylation with an additional benefit of recycling the greenhouse gas.

In order to prevent environmental degradation of the interface, a triplex coating was employed as the interface in ceramic matrix composites (CMC). This interface consists of an initial BN layer followed by a Si3N4 layer and lastly another BN layer. Single strand unidirectional mini-composites using BN/Si3N4/BN coated ceramic grade Nicalon™ fibers as the reinforcement and chemical vapor infiltrated (CVI) SiC as the matrix were fabricated to understand the initial properties of the interfacial coating. Field emission scanning electron microscopy (FE-SEM) confirmed the thickness of the triplex coating before and after mini-composite fabrication. FE-SEM micrographs after mechanical and environmental testing of the single strand unidirectional mini-composites showed the consequences of using the triplex interfacial coating. Finally, eight ply continuous fiber reinforced (CFR) CMCs with the BN/Si3N4/BN triplex interface and the traditional BN/Si3N4 duplex interface were fabricated using the polymer impregnation and pyrolysis (PIP) process. The PIP process has gained popularity in recent years and this allows for the fabrication of larger CMC panels as compared with the CVI process. Mechanical testing for the PIP-fabricated CFR-CMC panels showed that the composites using the triplex interface had better mechanical properties than those fabricated with a BN/Si3N4 duplex interface after environmental testing.
