Abstract: Carbon nanotubes (CNTs), a fascinating new member of the carbon-materials family, have been the focus of research due to their unique 1-dimensional structures. They exhibit great potential in applications such as composite reinforcements, field emitters for flat panel display, sensors, energy storage and energy conversion devices, and catalysts support phases, because of their extraordinary mechanical, electrical, thermal and structural properties. In particular, large specific surface areas, as well as the high chemical and thermal stabilities, potentially present CNTs as an attractive adsorbent in wastewater treatment. The aim of the present study is to demonstrate the capability of producing high quality CNTs with GNS’s newly built arc discharge apparatus and to determine synthesis and purification protocols for making good quality CNTs at low cost. Thereafter, to explore field emission properties of CNTs and to search for future environmental protection applications, such as waste treatment and purification of air streams. (auth)
