Abstract :This study aims to investigate the suitability of methanol as a carbon source for the synthesis of carbon nanofibres insert ignore into journalissuearticles values(CNFs);, currently used in wastewater, water, and air purification systems, by chemical vapor deposition insert ignore into journalissuearticles values(CVD); in the presence of NiO catalyst. Experimental studies were carried out in a tube furnace under isothermal conditions. Catalyst particles were loaded onto silicon wafers with orientation by dip coating to grow CNFs. The reduction behavior of nickel oxide powder at 1000 K under non-isothermal and isothermal conditions was investigated before CNF synthesis studies. The percentage reduction of nickel oxide powder under non-isothermal conditions was 82.03%. The percentage reduction under isothermal conditions for 30 min was 78.03%. The experimental result obtained is very close to the theoretical value insert ignore into journalissuearticles values(78.57%);. During CNF synthesis experiments, it was observed that CNF formation was not achieved at temperatures of 1000 - 1100 K due to the poor thermal decomposition of methanol. Pyrolysis of methanol increased with increasing synthesis temperature insert ignore into journalissuearticles values(1200 K);, which promoted the synthesis of CNFs. SEM analysis revealed morphologically dense CNF formation under isothermal conditions for 20 min at 1300K synthesis temperature.
