Photocatalytic Properties of Silver Loaded TiO2 Powders prepered by Mechanical Ball Milling

Yıl 2014, Cilt: 14 Sayı: 3, 239 - 247, 01.12.2014

Öz

Silver (Ag) was loaded to three different kinds of TiO2 powders (P25, NT-22, and TiO(OH)2) through adding three different quantities (4.6, 9.2, and 13.8 ml) of AgNO3 solution and milling 1hour in a planetary ball mill. Photocatalytic activity of as-received, only milled, and Ag loaded TiO2 powders was determined in terms of the decomposition of methyl orange (MO) solution under UV light irradiation. XRay diffraction analysis clarified that Ag was loaded onto the TiO2 powders as AgO. Scanning electron microscope, particle size, and BET surface area analyses revealed that particle size of the TiO2 powders decreased but, due to agglomeration their specific surface area also decreased after ball milling.

Mekanik Bilyalı Öğütme Yöntemiyle Gümüş Yüklenmiş TiO2 Tozlarının Fotokatalitik Özellikleri

Üç farklı özelliktekititanyum dioksit (TiO2) tozuna [P25, NT-22, ve TiO(OH)2] üç farklı miktarda (4,6, 9,2, ve 13,8 ml) AgNO3 çözeltisi ilavesiyle gezegensel bilyalı değirmende 1 saat süreyle öğütülerek gümüş (Ag) yüklemeleri yapılmıştır. Hiçbir işlem görmemiş, sadece öğütülmüş, ve öğütülerek Ag yüklenmiş TiO2tozların fotokatalitik etkinlikleri metilen turuncusunun (MO) ultraviyole (UV) ışık altında bozunumuna bağlı olarak belirlenmiştir. X-Ray kırınım analizi Ag’nin TiO2 tozlarının üzerine AgO olarak yüklendiğini göstermiştir. Taramalı elektron mikroskobu, parçacık boyut, ve BET özgül yüzey alanı analizleri bilyalı öğütmeden sonra TiO2 parçacıklarının boyutlarının küçüldüğünü, fakat topaklandıkları için özgül yüzey alanlarının azaldığını ortaya çıkarmıştır. Öğütülmemiş ve gümüş yüklenmemiş başlangıç P25, NT-22 ve TiO(OH)2 tozları 1 saat UV ışıması altında MO çözeltisini sırasıyla %94, %46, ve %26 bozundurmuştur. Ag yüklemeleri TiO2 tozlarının UV ışınımı altındaki fotokatalitik aktivitesini arttırmıştır. En iyi fotokatalitik performansı 13,8 ml AgNO3 çözeltisi eklenerek öğütülen NT-22 tozları göstermiştir.13,8 ml AgNO3 çözeltisi eklenerek öğütülen P25, NT-22 ve TiO(OH)2 tozları 1 saat UV ışınımı altında MO çözeltisini sırasıyla %85, %96 ve %67 bozundurmuştur. Elde edilen bulgular mekanik bilyalı öğütmenin TiO tozunun boyut küçültmesinde kullanılabileceği gibi TiO2 tozuna gümüş yüklenmesinde de kullanılabilecek alternatif bir yöntem olduğunu ortaya koymuştur.Gümüş yüklenmiş TiO2 tozu başlangıç TiO2 tozuna göre UV ışınımı altında MO çözeltisini daha kısa sürede parçalamaktadır.
