Clean and time-effective synthesis of anatase TiO 2 nanocrystalline by microwave-assisted solvothermal method for dye-sensitized solar cells

Easy and Fast Preparation of TiO2 - based Nanostructures Using Microwave Assisted Hydrothermal Synthesis

“…They obtained anatase nanoparticles with ~ 20 nm in diameter and surface area of 152 m 2 /g which were used in DSSC with conversion efficiency of 7.8%. 25 Thus our results indicate that the synthesized nanoparticles with up to 375 m 2 /g of surface area have great potential in DSSC.…”

“…[17][18][19] This technique provides uniform distribution of energy inside the sample, better reproducibility and excellent control over experimental parameters. 21 Microwave reactions were found to reduce the hydrothermal synthesis time of TiO 2 by typically 1/3, 16,[22][23][24][25] and in addition can produce single crystals, with less waste and lower temperatures. TTIP is commonly used in conventional and microwave assisted hydrothermal synthesis of TiO 2 under acid conditions, 1,3,[8][9][10]26 but less in alkaline.…”

Microwave-assisted synthesis of titanium dioxide nanocrystalline for efficient dye-sensitized and perovskite solar cells

“…However, the cost for the single crystal formation would require a longer reaction time of 60 min. Another method worth noting is the microwave-solvothermal process that prevented the water content in the reaction which could avoid the subsequent tedious solvent exchange procedure (Dar et al, 2014;Shen et al, 2014). We have achieved 7.8% efficiency DSCs with the microwave-solvothermal synthesized TiO 2 in a previous publication (Shen et al, 2014).…”

“…Moreover, its unique advantages of volumetric heating and energy saving in comparison with the conventional hydrothermal method are impressive (Baghbanzadeh et al, 2011). Recently the microwave synthesis has been applied to fabricate TiO 2 or titanate with great success for dye solar cells or battery Huang et al, 2011;Manseki et al, 2013;Parmar et al, 2011;Shen et al, 2014;Wang et al, 2011). Lately, mesoscopic or thin film TiO 2 has shown its great importance for perovskite solar cells.…”

Hydrogen Production Through Water Splitting Reaction Using Titanium Dioxide (Tio2) Nanotubes Photocatalyst

“…TiO 2 photocatalyst, especially TiO 2 nanotubes are attractive attributed to their non-toxicity, inexpensive, stable against photocorrosion and chemical corrosion [6]. TiO 2 nanotubes was explored as a photocatalyst for energy generation such as methane and methanol through carbon dioxide (CO 2 ) photo-reduction [7] and was widely used in electrochemical devices, photovoltaic dye sensitized solar cells and gas sensors application [8][9][10]. This is due to their large surface area, large surface to volume ratio and with uniform inner and outer diameters of the nanotubes make these elongated hollow structures an excellent candidate as photocatalyst [11].…”
