Recent Advances in Ultralow‐Pt‐Loading Electrocatalysts for the Efficient Hydrogen Evolution

Abstract

Hydrogen production from water electrolysis provides a green and sustainable route. Platinum (Pt)-based materials have been regarded as efficient electrocatalysts for the hydrogen evolution reaction (HER). However, the large-scale commercialization of Pt-based catalysts suffers from the high cost. Therefore, ultralow-Pt-loading electrocatalysts, which can reach the balance of low cost and high HER performance, have attracted much attention. In this review, representative promising synthetic strategies, including wet chemistry, annealing, electrochemistry, photochemistry, and atomic layer deposition are summarized. Further, the interaction between different electrocatalyst components (transition metals and their derivatives) and Pt is discussed. Notably, this interaction can effectively accelerate the kinetics of the HER, enhancing the catalytic activity. At last, current challenges and future perspectives are briefly discussed.

Electrolyte modification method induced atomic arrangement in FeOx/NF nanosheets for efficient overall water splitting

“…Currently, noble metal materials are dominating as the benchmark electrodes for HER. 4 For example, Lin et al 5 reported that RuO 2 /NiRu exhibited a Tafel slope of 33 mV dec −1 and an overpotential of 13 mV to reach a current density of 10 mA cm −2 for HER. Nevertheless, the high price and scarcity of these noble metals seriously impede their application.…”

Enhance Hydrogen Evolution Reaction Performance via Double-Stacked Edges of Black Phosphorene

“…At present, steam methane reforming (SMR) is the main industrial hydrogen production method, and it consumes a large amount of CH 4 during this process. , So, it cannot achieve absolute green energy from the source. The hydrogen evolution reaction (HER), using highly active catalytic electrodes to achieve low overpotential hydrogen production, has realized efficient electrolysis of commercial hydrogen production. − Up to now, the Pt is commonly recognized as the highly efficient HER catalyst with wide applications . However, high cost and scarcity hinder the massive use of Pt in industrial production.…”

“…4−9 Up to now, the Pt is commonly recognized as the highly efficient HER catalyst with wide applications. 10 However, high cost and scarcity hinder the massive use of Pt in industrial production.

Boride-induced phase tuning of defect-introduced MoS2 nanosheets to boost the electrocatalytic hydrogen evolution reaction

“…4–6 At present, expensive platinum-group noble metals have been established as the most effective HER electrocatalysts with extremely high catalytic activity and low overpotentials. 7–9 However, high cost and low availability restrict their widespread application. 10,11 Therefore, it is necessary to design efficient alternative HER electrocatalysts based on nonprecious metals.…”
