Consideration of surface morphology using scanning electron microscope (SEM) shows that, with anodizing, micro porous layer on titanium surface was prepared. The electro catalytic behavior of this type of electrodes in the isopropanol electro oxidation and in the chlorine evolution reaction was studied. Comparison of electro catalytic activity of this type of electrodes with platinum electrodes shows that, these electrodes have more than electro catalytic activity of platinum electrodes. Thereby we can use of this type of electrodes in chloro-alkaline industry as a suitable anodes. ﺳﺎﺧﺖ ﺳﺎﺧﺖ ﺁﻧﺪﻫﺎﻳﻲ ﺁﻧﺪﻫﺎﻳﻲ ﺑﺎ ﺳﻄﺢ ﻣﻮﺛﺮ ﻛﺎﺗﺎﻟﻴﺴﺘﻲ ﺑﺎﻻ ﺑﺎ ﺳﻄﺢ ﻣﻮﺛﺮ ﻛﺎﺗﺎﻟﻴﺴﺘﻲ ﺑﺎﻻ ﻭ ﺑﺮﺭﺳﻲ ﺭﻓﺘﺎﺭ ﻭ ﺑﺮﺭﺳﻲ ﺭﻓﺘﺎﺭ ﺘﺮﻭﺷﻴﻤﻴﺎﻳﻲ ﺁﻧﻬﺎ ﺩﺭ ﻭﺍﮐﻨﺶ ﺁﺯﺍﺩ ﺷﺪﻥ ﮔﺎﺯ ﮐﻠﺮ ﺍﻟﺘﺮﻭﺷﻴﻤﻴﺎﻳﻲ ﺁﻧﻬﺎ ﺩﺭ ﻭﺍﮐﻨﺶ ﺁﺯﺍﺩ ﺷﺪﻥ ﮔﺎﺯ ﮐﻠﺮ ﺍﻟ ﻣﻴﺮ ﻣﻴﺮ ﻗﺎﺳﻢ ﺣﺴﻴﻨﻲ، ﻗﺎﺳﻢ ﺣﺴﻴﻨﻲ، ﺳﻴﺪﺍﺑﻮﺍﻟﻔﻀﻞ ﺳﻴﺪﺳﺠﺎﺩﻱ ﺳﻴﺪﺍﺑﻮﺍﻟﻔﻀﻞ ﺳﻴﺪﺳﺠﺎﺩﻱ ﻭ ﻭﺪﻣﺤﺴﻦ ﻣﻮﻣﻨﻲ ﻫﺎﻣﺎﻧﻪ ﻣﺤﺪﻣﺤﺴﻦ ﻣﻮﻣﻨﻲ ﻫﺎﻣﺎﻧﻪ ﻣﺤ ﭼﮑﻴﺪﻩ: ١ ﺍﻟﻜﺘﺮﻭﺩﻫﺎﻳﻲ ﺑﺎ ﺳﻄﺢ ﻣﻮﺛﺮ ﻛﺎﺗﺎﻟﻴﺴﺘﻲ ﺑﺎﻻ, ﺍﺯﻃﺮﻳﻖ ﺁﻧﺪﺍﻳﺰﻳﻨﮓ ﺗﻴﺘﺎﻧﻴﻮﻡ ﻭ ﺳﭙﺲ ﺁﺑﮑﺎﺭﻱ ﭘﻼ ﺗﻴﻦ ﺑﺮ ﺭﻭﻱ ﺳﻄﺢ ﺗﻴﺘﺎﻧﻴﻮﻡ ﺁﻧﺪﺍﻳﺰ ﺷﺪﻩ, ﺳﻨﺘﺰ ﺷﺪﻧﺪ. ﺑﺮﺭﺳﻲ ﻣﻮﺭﻓﻮﻟ ﻮﮊﻱ ﺳﻄﺢ ﺗﻮﺳﻂ ﻣﻴﮑﺮﻭﺳﮑﻮﭖ ﺍﻟﮑﺘﺮﻭﻧﻲ ﺭﻭﺑﺸﻲ، ﻧﺸﺎﻥ ﺩﺍﺩ ﮐﻪ ﺩﺭ ﺍﺛﺮ ﺁﻧﺪﺍﻳﺰﻳﻨﮓ, ﻳﮏ ﻻﻳﻪ ﺧﻠﻞ ﻭ ﻓﺮﺝ ﺩﺍﺭ, ﺑﺮ ﺭﻭﻱ ﺳﻄﺢ ﺗﻴﺘﺎﻧﻴﻮﻡ ﺍﻳﺠﺎﺩ ﻣﻲ ﺷﻮﺩ. ﻓﻌﺎﻟﻴﺖ ﺍﻟﻜﺘﺮﻭﻛﺎﺗﺎﻟﻴﺴﺘﻲ ﺍﻳﻦ ﺍﻟﻜﺘﺮﻭﺩﻫﺎ ﺩﺭ ﺁﺯﺍﺩﺷﺪﻥ ﮔﺎﺯ ﮐﻠﺮ ﻭ ﺍﮐﺴﻴﺪﺍﺳﻴﻮﻥ ﺍﻟ ﮑﺘﺮﻭﺷﻴﻤﻴﺎﻳﻲ ﺍﻳﺰﻭﭘﺮﻭﭘﺎﻧﻮﻝ ﻣﻮﺭﺩ ﺑﺮﺭﺳﻲ ﻗﺮﺍﺭ ﮔﺮﻓﺖ. ﻣﻘﺎﻳﺴﻪ ﻓﻌﺎﻟﻴﺖ ﺍﻟﻜﺘﺮﻭﻛﺎﺗﺎﻟﻴﺴﺘﻲ ﺍﻳﻦ ﺍﻟﻜﺘﺮﻭﺩﻫﺎ ﺑﺎ ﺍﻟﻜﺘﺮﻭﺩ ﭘﻼﺗﻴﻦ، ﻧﺸﺎﻥ ﺩﺍﺩ ﻛﻪ، ﺍﻳﻦ ﺍﻟﻜﺘﺮﻭﺩﻫﺎ ﻓﻌﺎﻟﻴﺖ ﺍﻟﻜﺘﺮﻭﻛﺎﺗﺎﻟﻴﺴﺘﻲ ﺑﺴﻴﺎﺭ ﺑﻴﺸﺘﺮﻱ ﻧﺴﺒﺖ ﺑﻪ ﺍﻟﻜﺘﺮﻭﺩ ﭘﻼﺗﻴﻦ ﺍﺯ ﺧﻮﺩ ﻧﺸﺎﻥ ﻣﻲ ﺩﻫﻨﺪ. ﺑﻨﺎﺑﺮﺍﻳﻦ ﻣﻲ ﺗﻮﺍﻥ ﺍﺯﺍﻳﻦ ﺍﻟﮑﺘﺮﻭﺩﻫﺎ، ﺑﻪ ﻋﻨ ﻮﺍﻥ ﻳﮏ ﺍﻟﮑﺘﺮﻭﺩ ﻣﻨﺎﺳﺐ, ﺩﺭ ﺻﻨﺎﻳﻊ ﮐﻠﺮﻭﻗﻠﻴﺎ ﺍﺳﺘﻔﺎﺩﻩ ﮐﺮﺩ. ﻭﺍﮊﻩ ﻫﺎﻱ ﮐﻠﻴﺪﻱ: ﺁﺑﮑﺎﺭﻱ ﭘﻼﺗﻴﻦ, ﮐﻠﺮﻭﻗﻠﻴﺎ, ﻓﻌﺎﻟﻴﺖ ﺍﻟﮑﺘﺮﻭﮐﺎﺗﺎﻟﻴﺴﺘﻲ، ﺍﻟﮑﺘﺮﻭﺩﻫﺎﻱTi / Pt/TiO 2 ﺗﺎﺭﻳﺦ ﻭﺻﻮﻝ: ٣٠ / ٩ / ٨٥ ﺗﺎﺭﻳﺦ ﺗﺼﻮﻳﺐ: ١٧ / ١٢ / ٨٧ ﺩﮐﺘﺮ ﺩﮐﺘﺮ ﻣﻴﺮﻗﺎﺳﻢ ﺣﺴﻴﻨﻲ، ﻣﻴﺮﻗﺎﺳﻢ ﺣﺴﻴﻨﻲ، ﺩﺍﻧﺸﻴﺎﺭ ﺩﺍ ﻧﺸﮑﺪﻩ ﺷﻴﻤﻲ، ﺩﺍﻧﺸﮕﺎﻩ ﺗﺒﺮﻳﺰmg-hosseini@tabrizu.ac.ir ﺩﮐﺘﺮ ﺩﮐﺘﺮ ﺳﻴﺪﺍﺑﻮﺍﻟﻔﻀﻞ ﺳﻴﺪﺳﺠﺎﺩﻱ، ﺳﻴﺪﺍﺑﻮﺍﻟﻔﻀﻞ ﺳﻴﺪﺳﺠﺎﺩﻱ، ﺍﺳﺘﺎﺩ ﺩﺍﻧﺸﮑﺪﻩ ﺷﻴﻤﻲ، ﺩﺍﻧﺸﮕﺎﻩ ﻋﻠﻢ ﻭ ﺻﻨﻌﺖ ﺍﻳﺮﺍﻥseyedsadjadi@yahoo.com ﻣﺤﻤﺪﻣﺤﺴﻦ ﻣﻮﻣﻨﻲ ﻫﺎﻣﺎﻧﻪ، ﻣﺤﻤﺪﻣﺤﺴﻦ ﻣﻮﻣﻨﻲ ﻫﺎﻣﺎﻧﻪ، ﺩﺍﻧﺸﺠﻮﻱ ﺩﮐﺘﺮﺍﻱ ﺷﻴﻤﻲ ﻓﻴﺰﻳﮏ، ﺩﺍﻧﺸﮕﺎﻩ ﺗﺒﺮﻳﺰm-momeni@tabrizu.ac.ir
