In this present investigation titanium dioxide (TiO2) nano-fluid was blended with aphanizomenon flos (AF) biodiesel (20%)-diesel (80%) blend. Different percentages of TiO2 such as 5%, 10%, and 15%, was added with AF-D (aphanizomenon flos-diesel) blends. The blends are named as AFD-5TiO2, AFD-10TiO2, and AFD-15TiO2. The performance and emission parameters of a single cylinder CI engine fueled with AFD-TiO2 blends were experimentally investigated. The results reveal that, with the use of TiO2 nano particles, AFD-10TiO2 blend gave optimum results. BSFC decreased by about 5% and BTE increased by about 2% with the addition of TiO2 nano-particle as a catalyst. The tailpipe emissions such as CO, HC, smoke reduced drastically, but the NO emission increased, with the use of TiO2 nano-particles.

A study on the formation of titanium dioxide (TiO2)/ polyvinyl alcohol (PVA) nanofibres has been investigated in the research work. In the study, the TiO2/PVA solutions were prepared at different concentrations ranging from 1wt% to 10wt%. The PVA solution without TiO2 was used as control sample in the study. Each solution was extruded using electrospinning at different voltages to form long and continuous nanofibres. The fibres were then characterised for morphological structures, fibre diameter and membrane area. The result shows that control sample of PVA nanofibres formed beads on the fibre surfaces. The addition of TiO2 in PVA was found to reduce the bead formation. The clumps of TiO2 nanoparticles were observed and were also confirmed with the EDX mapping. In addition, the electrospinning parameters affect the formation of TiO2/PVA nanofibers. At 15 kV, the resultant fibre diameter increases from 153 ± 23 nm to 191 ± 26 nm when the TiO2 concentration was further increased from 1wt% to 10wt%. The morphological structure of TiO2/PVA nanofibres varies depending on applied voltages and concentrations used. The membrane area of TiO2/PVA nanofibers is approximately 187 cm2 for 1wt% of TiO2. From the study, it shows that an optimalconcentration to produce TiO2/ PVA nanofibers is 10wt%. At 10wt%, no beads were observed on the fibre and the TiO2 nano-particles were uniformly distributed on the membrane surfaces.

Titanium dioxide also known as titania is a ceramic material. It is probably the most investigated inorganic oxide in recent years because of its non toxic nature, chemical stability and its potential effectiveness for destruction of toxic organic compounds in industrial effluents. In the present study pure and Ta doped TiO2 nanosize particles were prepared by sol-gel method. Samples with doping concentrations varying from 0.50 to 1.50 at % Ta and calcinations temperatures from 300 to 900 oC were synthesized. Changes taken place in phase transformation of the samples doped with Ta and undoped TiO2 were investigated. The effect of dopant concentration, calcinations temperature and particles size on anatase to rutile phase transformation was studied in detail. The samples were analyzed by various standard analytical tools.
