PdPbAg alloy NPs immobilized on reduced graphene oxide/In2O3 composites as highly active electrocatalysts for direct ethylene glycol fuel cells

“…It is well known that a smaller R ct value is beneficial to the charge transfer from electrode to fuel, reducing the activation barrier of fuel oxidation and electrode reaction overpotential. 44 Therefore, PdPbAg@rGO/In 2 O 3 has the most superior charge transport characteristics and the largest reaction driving force. 46 …”

“…In the meantime, the peak potential (n) of the CV curves shis continuously, indicating that the electrocatalytic oxidation of EG on the PdPbAg@rGO/In 2 O 3 catalyst electrode is an irreversible electrode process. 44 Furthermore, the linear relationship between the square root scan velocity (n 1/2 ) and the forward peak current density is shown in Fig. 6(B).…”

“…The charge transfer resistance of the catalyst was evaluated as a semicircular diameter. Compared with PdPb@rGO/In 2 O 3 (9.52 U), PdAg@rGO/In 2 O 3 (16.05 U), Pd@rGO/In 2 O 3 (19.21 U) and Pd/C (35.19 U), PdPbAg@rGO/In 2 O 3 (8.65 U) has minimal impefance.It is well known that a smaller R ct value is benecial to the charge transfer from electrode to fuel, reducing the activation barrier of fuel oxidation and electrode reaction overpotential 44. Therefore, PdPbAg@rGO/In 2 O 3 has the most superior charge transport characteristics and the largest reaction driving force 46.…”

Synthesis of Free‐Standing Alloyed PdSn Nanoparticles with Enhanced Catalytic Performance for Ethanol Electrooxidation

“…Both Tafel and EIS data indicate that the Pd 20 Sn 24 NPs have the lowest reaction barrier on EOR, greatly improving its electrocatalytic activity, consistent with the results derived from CV curves mentioned above. [39] To analyze the kinetic mechanism of Pd x Sn y NPs on EOR, [30] the catalytic temperature, pH value, and concentration of ethanol were tuned and/or controlled. In Figure . 6 A, the mass activity of Pd 20 Sn 24 NP increases from 2016 mA mg À 1 to 3070 mA mg À 1 when the temperature increases from 30 °C to 60 °C.…”

Preparation of highly reflective silver metallized PVC film by autocatalytic deposition

“…As shown in Figure 2(a), the peaks at 366.9, 372.9, 573.6, and 604.0 eV correspond to Ag 3d 5/2 , Ag 3d 3/2 , Ag 3p 3 , and Ag 3p 1 , respectively, which are the characteristic peaks of Ag. 30 The peak at 532.3 eV corresponds to Pd 3p 3, 31 which is the characteristic peak of Pd. These results indicated the existence of Ag and Pd elements on the surface of the PVC film.…”
