Low-temperature-dependent growth of titanium dioxide nanorod arrays in an improved aqueous chemical growth method for photoelectrochemical ultraviolet sensing

Tuning atomically precise metal nanocluster mediated photoelectrocatalysis via a non-conjugated polymer

“…1h, the Raman spectra of all the photoanodes show similar peaks at approximately 143 cm −1 (B 1g ), 230 cm −1 (two-phonon bands), 449 cm −1 (E g ) and 611 cm −1 (A 1g ), 45 wherein the E g and A 1g vibration modes correspond to TiO 2 . 46 Similarly, the peaks corresponding to the Ag x NCs are not observed due to the low loading amount, which is in good agreement with the XRD results. Notably, T(PA) 4 demonstrates the weakest peak intensity, which might be attributed to the shielding effects of the PDDA and Ag x NCs.…”

Performance Analysis of Calcium-Doped Titania (TiO2) as an Effective Electron Transport Layer (ETL) for Perovskite Solar Cells

“…To determine the structural properties and to check the effect of the Ca-TiO 2 structure, XRD analysis was characterized by D8 Advance (Bruker Advanced, Berlin, Germany) [24] and a radiation wavelength of 1.5418 Å in the range of 2θ = 10 • to 80 • with a step size of 0.05 • /5 s. MDI Jade 6.5 software was used to investigate the crystallinity. Further crystallite size, microstrain, and dislocation density were calculated by using the Sherrer's equation and Williamson and Smallman's relation, as presented in the following Equations ( 1)-(3) [25][26][27][28].…”

Preparation of Bi/BiOBr sensitized titania nanorod arrays via a one-pot solvothermal method and construction of kanamycin photoelectrochemical aptasensors

“…27 As an n-type semiconductor, titania (TiO 2 ) has become an ideal material for constructing PEC sensors because of its low toxicity, low cost, adjustable morphology, and high photocatalytic performance. 28 A one dimensional TiO 2 nanorod array (TiO 2 NRA) provides a direct current channel for electrons to transmit quickly. 29 In addition, the slender shape of one-dimensional TiO 2 nanorods has a vast aspect ratio and a high collection rate of visible light.…”
