Influence of tartaric acid on diffusion coefficients of BiIII, SbIII, TeIV in aqueous medium: Application of electrodeposition of thermoelectric films

A Dealloying Synthetic Strategy for Nanoporous Bismuth–Antimony Anodes for Sodium Ion Batteries

“…Schoenleber et al reported that the diffusion coefficient (D = 12.2 × 10 −6 cm 2 /s) of Bi is nearly two times that (D = 7.0 × 10 −6 cm 2 /s) of Sb in 0.10 M tartaric acid. 55 In this work, the concentration of the tartaric acid is 2 wt % (equal to 0.13 M), close to that in the work by Schoenleber et al, indicating that Bi can diffuse quickly in comparison with Sb in the 2 wt % tartaric acid. During the dealloying process, the size of ligaments is significantly influenced by surface diffusion of more noble atoms, and increases with increasing diffusion coefficients of them.…”

“…(1) The diffusion coefficients of Bi and Sb are different in aqueous solutions. Schoenleber et al reported that the diffusion coefficient ( D = 12.2 × 10 –6 cm 2 /s) of Bi is nearly two times that ( D = 7.0 × 10 –6 cm 2 /s) of Sb in 0.10 M tartaric acid . In this work, the concentration of the tartaric acid is 2 wt % (equal to 0.13 M), close to that in the work by Schoenleber et al , indicating that Bi can diffuse quickly in comparison with Sb in the 2 wt % tartaric acid.…”

Growth Mechanism during the Early Stages of electrodeposition of Bismuth telluride films

“…All potentials were measured and expressed related to the reference electrode (KCl saturated Ag/AgCl electrode, Bioblock). The syntheses were conducted at fixed applied potential of À25 mV to obtain the required binary stoichiometry [16][17][18][19][20]. The growth times were fixed to 60 s. EQCM sensors, composed of gold films evaporated on glass (5 MHz AT-cut quartz from Maxtek, Inc., Ref.…”

Sampling of dissolved inorganic SbIII by mercapto-functionalized silica-based diffusive gradients in thin-film technique

“…Although the diffusion coefficient of Sb III in aqueous solution has not been reported in the literature, diffusion coefficient of 7.0 Â 10 À6 cm 2 s À1 for Sb III in 1 mol L À1 of HNO 3 solution has been previously reported. 26 The diffusion coefficients of metals have been signicantly affected by ionic strengths of solution and decrease with the increase of ionic strengths. 8,27 In this work, the same trend has been obtained.…”
