Titanium dioxide (TiO<inf>2</inf>) nanopowder was prepared by the low temperature solvothermal route with starting chemicals containing titanium isopropoxide, ammonium hydroxide, nitric acid and ethanol in a PTFE-lined autoclave. The final pH of the mixed solution was 1 and treated at 100 °C for 2-6 h. The white precipitated was filtered and dried in an oven at 80 °C for 24 h. The phase transition was characterized by X-ray diffractometer (XRD). Single phase anatase structure was obtained without calcination step. The morphology and particle size of TiO<inf>2</inf> nanopowder was investigated by scanning electron microscope (SEM). The average of TiO<inf>2</inf> nanopowder size was 80-120 nm. The average particle size increased with temperature and time increased. The photocatalytic degradation of methomyl in natural water was studied by high performance liquid chromatograph (HPLC). The percentage of methomyl was decreased in the presence of 34, 23 and 24 over TiO<inf>2</inf>nanopowder prepared by the low temperature solvothermal route at 100 °C for 2, 4 and 6 h, respectively. 2018-09-04T10:15:47Z 2018-09-04T10:15:47Z 2015-01-01 Book Series 02555476 2-s2.0-84918494933 10.4028/www.scientific.net/MSF.804.209 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84918494933&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/54540
