“…The Pt 4f 7/2 signal at 71.5 eV can be assigned to zero-valent platinum (Pt 0 ). The binding energy value for the metallic platinum (Pt 0 ) is in agreement with the literature data [21,22]. The relative shift from the value of 70.8 eV for the bulk metal is probably due to a contribution from metal-support interaction or small cluster-size effects [23].…”

The MoS 2 :TiO 2 :Pt counter electrode (CE) treated using argon plasma provides possibilities to improve photovoltaic performance of dye-sensitized solar cells (DSSCs). The experimental results revealed that the argon plasma-treated MoS 2 :TiO 2 :Pt composite influences on the power conversion efficiency by enhancing electrocatalytic activity that serves to increase the short circuit current. The findings show the importance of plasma treatment time in achieving optimization of DSSCs. The induced conversion of chloroplatinic acid into metallic Pt on the CE surfaces by argon plasma treatment promotes the overpotential modification at the MoS 2 :TiO 2 :Pt CE/electrolyte interfaces, resulting in the increased probability of the reduction of triiodide to iodide.

“…The obvious reason might be a smaller size of Pt particles of the Pt/ C catalyst [70]. Very recently Ruiz-Camacho et al proposed that the TiO 2 loading on carbon material is an essential parameter that should be taken into account [74]. In their study Pt-TiO 2 -C samples prepared with TiO 2 loading of 5 wt.% resulted in homogeneous oxide dispersion with an enhanced metal-oxide interaction, compared to 15 wt.% Pt-TiO 2 -C catalyst, which had lower electronic transfer to carry out the electrocatalysis of the ORR.…”
