Hydrogen evolution in alkaline medium on intratube and surface decorated PtRu catalyst

Galvanic replacement-induced preparation of bloom-like Pt23Ni77 for methanol coupled efficient hydrogen production

“…In addition, considering that C dl value was proportional to the electrochemical active surface area (ECSA), 36 we calculated the electrochemical double layer capacitance (C dl ) using cyclic voltammetry (CV) at different scan rates within the non-faradaic potential region to determine the source of the increased electrocatalytic activity of the Pt x Ni y (Fig. S10-11 †).…”

Alloy/strain engineering of Pt-based nanowires with controllable electronic structures towards boosted water electrolysis catalysis

“…In recent years, one-dimensional (1D) Pt-based nanowires (NWs) have provided an alternative approach to address the bottleneck of catalytic efficiency because of their out-bound intrinsic activity, fascinating properties, and promising applications in electrocatalysis. [18][19][20][21][22][23][24][25][26][27][28][29] Recent achievements indicated that strategies such as morphology engineering, [30][31][32][33] amorphization, 34 strain engineering, 35 defect engineering, 36 etc., can tune the surface electronic structures of metal catalysts, thus contributing to the optimization and improvement of the catalytic performance. For example, the strain on the surface changes the center position of the d-band relative to the catalyst Fermi level (e F ), which in turn affects the adsorbate-catalyst surface interaction.…”

Anchored RuSe2nanospheres on Co–N–C nanosheets boost electrocatalytic alkaline hydrogen evolution

“…[5][6][7][8] In the past decades, Pt-based electrocatalysts with excellent performance in alkaline media have been considered suitable HER catalysts for water electrolysis. [9][10][11][12] However, high cost and limited reserves greatly restrict the application of Pt-based catalysts. Therefore, an effective and inexpensive alternative Pt-based electrocatalyst needs to be developed to further accelerate the breakthrough in the HER.…”
