2021年12月13日 · Here, we report on an ingenious synthesis of hybrid Pt x Ni 1–x electrocatalysts in the form of a nanoparticle–nanonetwork structure with very low noble metal content.

2021年12月15日 · Characterization results from XRD, H2-TPR, XPS, STEM-EDX, in situ CO-DRIFT and EXAFS suggest that Ni-Pt/Al2 O 3 catalyst was more preferable to form Ni x+ species and NiPt alloy compared with Pt-Ni/Al 2 O 3 and NiPt/Al 2 O 3 catalysts.

2022年11月10日 · With a moderate Ni content and a homogenously alloyed bimetallic Pt–Ni structure, the PtNi2 catalyst displayed the highest reaction activity among all materials studied in this work. In situ FTIR data show that PtNi2 can activate the glycerol molecule at a more negative potential (0.4 VRHE) than the other PtNi catalysts.

2024年5月13日 · Here, we present an interaction-driven in-situ approach to engineer finely dispersed Ni decorated Pt nanoparticles (1-6 nm) on perovskite nanofibres via reduction at high temperatures (600-800...

通过X射线吸收光谱法和X射线研究了Pt-Ni合金（Pt-Ni = 3：1、1：1和1：3）中Pt和Ni的局部结构，多体效应以及电荷的重新分布。 射线光电子能谱（XPS）。 发现在合金化时，Pt金属中Pt 4f峰的倾斜多体线形在Pt合金中变得更加对称，而相关的Ni 2p峰变得更加不对称并且 ...

2015年3月2日 · In this work, we report a design strategy in which we grow one-dimensional (1D) ultrathin Pt nanowires (NWs) on two-dimensional (2D) Ni (OH) 2 nanosheets to construct the high performance...

2024年1月11日 · Herein, the hetero-nanocrystals between monodispersed Pt (~ 2 nm) and Ni 3 S 2 (~ 9.6 nm) are constructed as active electrocatalysts through interfacial electronic modulation, which exhibit superior bi-functional activities for methanol selective oxidation and H 2 generation.

2023年10月1日 · The physicochemical analysis provides evidence that the carbon nitride support allows the formation of highly dispersed PtNi nanoparticles with an average composition of Pt 85 % Ni 15 %. The binary system outperforms the monometallic Pt and Ni counterparts and renders an extraordinary quantum efficiency of 8.8 % for hydrogen photo-production.

2024年12月3日 · In this study, a novel N/P-doped Ni/Pt bimetallic catalyst is developed (NiPt@C-NP, 3.68 % Ni, 0.2 % Pt) using polyacrylonitrile fibers as an inexpensive carbon source for catalyst support. Due to strong anchoring from the N and P heteroatoms, the nickel and platinum species are mono-atomically dispersed throughout the catalyst.

Homogeneously mesoporous Ni–Pt thin films have been successfully synthesized by potentiostatic electrodeposition from an aqueous solution. The films are single-phase nanocrystalline Ni–Pt...
