A novel composite material based on carbon nanofibers (CNF) grown on sintered metal fibers (SMFInconel) filter was investigated for its favorable properties as catalytic support. The CNF were formed directly over the SMFInconel by thermal (650 8C) chemical vapor deposition of ethane–hydrogen mixture. The CNF/SMFInconel composite consists of metal fibers entangled by CNF network of microns thick...

Introduction: There are different methods for removal of cadmium from aqueous solutions. Adsorption based methods are among the bests. One of the most important aspects for adsorption techniques is the availability of an accessible and economical adsorbent. This study aims to investigate cadmium removal from aqueous solutions by walnuts shell waste. Materials and Methods: Walnut Shell (WS) was...
