Tailoring supports for enhancing the electrocatalytic hydrogen evolution performance of platinum species: a review

Abstract

Platinum (Pt)-based electrocatalysts have been identified as the most active materials for the hydrogen evolution reaction (HER). To further enhance the utilization efficiency and activity of Pt species, significant efforts...

Tailoring Zirconia Supported Intermetallic Platinum Alloy via Reactive Metal‐Support Interactions for High‐Performing Fuel Cells

“…[14] In addition, PtÀ Pt and PtÀ Ni coordinations are indistinguishable in R-space. [20] Therefore, the wavelet transforms analysis (Figure 2g-i and Figure S11) is carried out to further detect the local Pt coordination environments of the studied catalysts. The intensity maximum at ~9 Å À 1 which corresponds to PtÀ Ni bond is displayed in almost all samples except for Pt-ZrO 2 , confirming that PtNi alloys can be formed through the RMSI and direct loading.…”

Engineering ultrafine PtIr alloy nanoparticles into porous nanobowls via a reactive template-engaged assembly strategy for high-performance electrocatalytic hydrogen production

“…Currently, Pt is generally considered the best-performing electrocatalyst for the HER because of its vertex position in the HER volcano plot. 21–25 For further improvement of the HER performance of Pt catalysts, iridium (Ir), which locates at the neighboring site of Pt in the volcano plot, represents an attractive candidate for alloying with Pt. 26–28 The formation of binary PtIr alloys can significantly promote favorable electronic configuration, a unique coordination microenvironment, optimal hydrogen adsorption strength, and remarkable chemical stability, which can evidently enhance the HER catalytic performance.…”

Constructing self-supported Pt/MoO2 on molybdenum mesh for a highly efficient hydrogen evolution reaction

“…Loading Pt catalysts onto a support enhances the performance in hydrogen production, stability, and utilization rate. [13][14][15][16][17] The choice of support material is crucial for overall efficiency. The support material influences Pt particle dispersion, directly impacting the activity and stability.…”
