摘要

本研究是利用改良式真空潛弧製造系統(SANSS)來製備奈米二氧化鈦(TiO2)懸浮液，針對該製程之不同製備方式及製程參數，以期獲得較佳之二氧化鈦奈米懸浮顆粒製備條件。懸浮液所含之奈米顆粒在靜置過程中，成份方面會由似一氧化鈦轉變為二氧化鈦；在結晶組成方面，所製備之二氧化鈦顆粒之結晶組成為銳鈦礦(Anatase)結構；在光催化方面，所製備之奈米二氧化鈦懸浮液在光波長360nm~380nm時產生吸收紫外光現象，在吸附實驗中本製程所製備的二氧化鈦顆粒的吸附效果優於商用的二氧化鈦及氧化鋅，在亞甲基藍的脫色實驗中本製程所製備的二氧化鈦顆粒能在60分鐘內達到脫色率100%。

The purpose of this study is to use an innovation Submerged Arc Nanoparticles Synthesis System(SANSS) to prepare the titanium dioxide nanofluid, This study employs some major parameters to investigate the optimized process conditions for producing titanium dioxide nanoparticle. Composition of suspension will chang from titanium monoxide to titanium dioxide during standstill procedure. Experimental results show that the proposed method can successfully prepare the anatase phase of titanium dioxide .In the photocatalysis experiment, the prepared titanium dioxide nanofluid absorbs the Ultraviolet when light wavelength was 360 to 380 nm. Adsorption experimental results show that the efficiency of absorbing methylene blue using TiO2(SANSS) is higher than that for TiO2 (Degussa P-25) or ZnO. Depigmentation of methylene blue experimental using TiO2(SANSS) can depigmentize methylene blue reach 100% in 60 min.
