Self-assembled nanodendritic PdPtCu nanosheets/Ti₂CT_x–CNT electrocatalysts for low overpotential and long-term stable hydrogen evolution reaction

Abstract

Reducing the overpotential and achieving long-term stability of electrocatalysts are vital for facilitating the catalytic activity of hydrogen evolution reaction (HER). Herein, two-dimensional dendritic PdPtCu nanosheets were prepared and further...

Recent advances in noble metal MXene-based catalysts for electrocatalysis

“…Moreover, Qin and colleagues loaded PdPtCu nanosheets on a Ti 2 CT x -CNT composite support to construct an efficient HER catalyst. 149 The average lateral length of the PdPtCu nanosheets was 45 nm and their shape was an asymmetric snowake with many nano-branches and tiny gaps (Fig. 13f).…”

Research Progress of Highly Efficient Noble Metal Catalysts for the Oxidation of 5‐Hydroxymethylfurfural

“…Therefore, regulating the nanogeometric morphology of Pd to expose different facets is also an effective method regulate the electronic structure of Pd metal. [90] Lei et al used single-crystal Pd NPs wrapped by controllable sizes or facets for the HMF selective oxidation. [91] The study also found that PdÀ NOs wrapped in {111} facets was more conducive to the oxidation of HMF than PdÀ NCs wrapped in {100} facets (Figure 9), especially in the step of HMFCA À OH oxidation to form FFCA.…”

“…The electronic structure of Pd could change with the change of the exposed facets. Therefore, regulating the nano‐geometric morphology of Pd to expose different facets is also an effective method regulate the electronic structure of Pd metal [90] . Lei et al.…”

In situ growth engineering of ultrathin dendritic PdNi nanosheets on nitrogen-doped V2CTx MXenes for efficient hydrogen evolution

“…Electrostatic self-assembly and in situ reduction are two common strategies for constructing metal–MXenes hierarchical architectures. 35,36 Compared with a physical combination which usually easily results in shedding and agglomeration, the in situ growth method can not only induce a stronger coupling effect and interfacial charge transfer between catalysts and MXenes, 37 but also provide superior uniform distribution and stability to catalysts. 38 MXenes are suitable substrates for in situ growth engineering of various functional materials owing to their benefits such as a large surface area and abundant functional groups as nucleation sites.…”
