“…Moreover, the interaction of the electrocatalyst and electrolyte ions also enhanced the HER activity of Hy-Sr(OH) 2 -200 nanorods. 39 Meanwhile, nanopallets of Hy-Sr(OH) 2 -80 and the hybrid of nanopallets and nanorods of Hy-Sr(OH) 2 -140 could not provide the effective path and created the hindrance in the flow of charge carriers. Overpotential is the crucial parameter to evaluate the efficiency of the electrocatalysts.…”

Tremendous efforts have been directed to developing reliable electrocatalysts to gain clean hydrogen energy from water splitting and encounter energy challenges. The morphology at the nanoscale of electrocatalysts has also a significant influence on hydrogen evolution reaction. An alkaline-based electrocatalyst, strontium hydroxide hydrate, has been synthesized at temperatures of 80, 140, and 200 °C using the hydrothermal process. The employed growth temperature capably influences the morphology and intrinsic characteristics of the strontium hydroxide hydrate for the hydrogen evolution reaction. The mesoporous nature, greater electrochemical and specific surface area of nanorods, and facile proton donation by the acid jointly enhance the HER activity. Hy-Sr(OH)2-200 nanorods have exhibited a good overpotential of 84 mV in 0.5 M H2SO4 at the current density of 10 mA cm–2, which is better than the nanopallets (Hy-Sr(OH)2-80) and the hybrid morphology consisting of nanopallets and nanorods (Hy-Sr(OH)2-140). The mesoporous nature, greater electrochemical and specific surface area, and nanorod-like morphology have promoted and facilitated the adsorption and desorption of the active hydrogen atoms at the active sites inside the Hy-Sr(OH)2-200 nanorods. As a result, Hy-Sr(OH)2-200 nanorods exhibit the Tafel slope of 81 mV dec–1 in 0.5 M H2SO4 and follow the Volmer–Heyrovsky phenomena. Moreover, Hy-Sr(OH)2-200 nanorods show a good turnover frequency of 142.84 ms–1 at the fixed reversible hydrogen potential of 0.5 V, which is better than the other employed electrolytes and electrocatalysts fabricated at temperatures of 80 and 140 °C. The symmetric system, consisting of Hy-Sr(OH)2-200 nanorods, shows a good overpotential of 240 mV at a current density of 10 mA cm–2, along with a Tafel slope of 79 mV dec–1 in 0.5 M H2SO4. The electrocatalyst of Hy-Sr(OH)2-200 nanorods comprehensively exhibits good performance for the hydrogen evolution reaction.

“…Platinum (Pt)-based catalysts are currently the best-performing electrocatalysts in the HER; 8 carbon is commonly used as a support for these catalysts. The adhesion between Pt and carbon is weak, 9,10 and the performance degrades after a long operation time due to Pt particle exfoliation. 11,12 This carbon corrosion situation is also present in the DER, and enhancing the stability of the catalyst by modifying the support is a common strategy.…”

The design and synthesis of hollow and porous nanostructured electrode materials is an effective strategy to improve the electrochemical performance of lithium-ion batteries and the hydrogen evolution reaction (HER). Herein, we synthesize hollow and porous Co@Co3O4 nanoparticles embedded in N-doped CNTs (N-CNTs) with rich surface defects through a two-step calcination strategy. The formation mechanism is explored. The influence of oxygen vacancies regulated by the nanoscale Kirkendall effect on the electrochemical performance of the electrode is elucidated. The Co@Co3O4@N-CNTs exhibit remarkable activity for catalyzing the HER with a low onset overpotential of 296 mV (a low Tafel slope of 116.2 mV dec–1), much better than Co3O4@N-CNTs (315 mV for overpotential and 124.2 mV dec–1 for Tafel slope). Significantly, the Co@Co3O4@N-CNTs deliver a high discharge capacity of 990 mA h g–1 after 600 cycles at 0.1 A g–1. Our nanostructure strategy can provide new insights into the strategy for high-rate and highly stable energy storage systems.
