Cerium catalyst on the alumina support -- it is able to carry out the completely burned of carbon monoxide or hydrocarbon with excess oxygen

摘要

The present invention is an improved material and method for use for providing diffuse reflectivity of light. By employing an expanded polytetrafluoroethylene (PTFE) comprising a microstructure of polymeric nodes and fibrils, the material of the present invention demonstrates exceptional diffuse reflectivity across a wide spectrum of visible and infrared light. Additionally, the material of the present invention provides many properties that have been previously unavailable in highly diffuse reflective material, including a high degree of malleability, moldability and flexibility, and effective reflectivity even at relatively thin cross-sections.
