Early catalyst deactivation through the encapsulation of catalyst nanoparticles by amorphous carbon layer due to the oversupply of carbon source is one of the key elements that inhibit efficient carbon nanotubes (CNT) synthesis in flame environment. The present study utilizes methane diffusion flame...
