Since the 1970s, the increasingly serious environmental pollution, the harmful emissions of internal combustion engines by people attach great importance, but in the high-profile investment in environmental protection at the same time, shadow to the social and economic development. Nanotechnologies has undoubtedly become the solution.

Dr. Gan lin Hwang has reminded "nanotechnology materials may be the most important application of the 21st century, but it also could be the worest source of pollution". Stringent emission regulations, select the pure, low-cost, high-performance nano-materials to improve fuel quality will be the best foothold for the development of economic environmental.
