“…On the other hand, for the crystal investigation of Sumanene adsorption properties towards H-molecule. Rikalo et al 53 , 55 used the split DFT theory with both GGA and LDA approximations using PBEO functional, respectively, together with polarization atomic orbitals as basis set. For the Sumanene surfaces, adsorption energies ranging from − 0.830 to − 1.440 eV was obtained respectively, which is comparably better than other referenced engineered carbon-based illustrated nanostructures.…”

“…Hence, it was critically observed that an increase in Ni-doping, Ca-encapsulation, and Ag-decoration gradually increases the adsorption energy, bringing about more negative value of the adsorption energy. More so, literature and scientific assertions has showed that the greater/high negative value the adsorption energy, the stronger the bond between H and the catalyst systems, and at such more stable the system 55 . More so, the most craving site for an atomic hydrogen on the studied systems were also analyzed.…”

The utilization of nanostructured materials as efficient catalyst for several processes has increased tremendously, and carbon-based nanostructured materials encompassing fullerene and its derivatives have been observed to possess enhanced catalytic activity when engineered with doping or decorated with metals, thus making them one of the most promising nanocage catalyst for hydrogen evolution reaction (HER) during electro-catalysis. Prompted by these, and the reported electrochemical, electronic and stability advantage, an attempt is put forward herein to inspect the metal encapsulated, doped, and decorated dependent HER activity of C 24 engineered nanostructured materials as effective electro-catalyst for HER. Density functional theory (DFT) calculations have been utilized to evaluate the catalytic hydrogen evolution reaction activity of four proposed bare systems: fullerene (C 24 ), calcium encapsulated fullerene (Ca enc C 24 ), nickel-doped calcium encapsulated fullerene (Ni dop Ca enc C 24 ), and silver decorated nickel-doped calcium encapsulated (Ag dec Ni dop Ca enc C 24 ) engineered nanostructured materials at the TPSSh/GenECP/6-311+G(d,p)/LanL2DZ level of theory. The obtained results divulged that, a potential decrease in energy gap (E gap ) occurred in the bare systems, while a sparing increase was observed upon adsorption of hydrogen onto the surfaces, these surfaces where also observed to maintain the least E H–L gap while the Ag dec Ni dop Ca enc C 24 surface exhibited an increased electrocatalytic activity when compared to others. The results also showed that the electronic properties of the systems evinced a correspondent result with their electrochemical properties, the Ag-decorated surface also exhibited a proficient adsorption energy and Gibb’s free energy (ΔG H ) value. The engineered Ag-decorated and Ni-doped systems were found to possess both good surface stability and excellent electro-catalytic property for HER activities.

“…Here, we highlight the recent advances in the robust heterogeneous electrocatalysts for HER in various electrolytes. Generally, heterogeneous HER catalysts are classified into three categories (Figure 1): noble metal‐based (NMB), transition metal‐based (TMB), and metal‐free catalysts (MFC) 27–50 . This review addresses the current progress of catalytic stability of the heterogeneous HER electrocatalysts.…”

Developing new methodologies to produce clean and renewable energy resources is pivotal for carbon‐neutral initiatives. Hydrogen (H2) is considered as an ideal energy resource due to its nontoxic, pollution‐free, high utilization rate, and high calorific combustion value. Electrolysis of water driven by the electricity generated from renewable and clean energy sources (e.g., solar energy, wind energy) to produce hydrogen attracts great efforts for hydrogen production with high purity. Recently, the breakthrough of the catalyst activity limit for the hydrogen evolution reaction (HER) catalysts has received extensive attention. Comparatively, fewer reviews have focused on the long‐term stability of HER catalysts, which is indeed decisive for large‐scale electrolytic industrialization. Therefore, a systematic summary concentrated on the durability of HER electrocatalysts would provide a fundamental understanding of the electrocatalytic performance for practical applications and offer new opportunities for the rational design of the highly performed HER electrocatalysts. This review summarizes the research progress toward the HER stability of precious metals, transition metals, and metal‐free electrocatalysts in the past few years. It discusses the challenges in the stability of HER electrocatalysts and the future perspectives. We anticipate that it would provide a valuable basis for designing robust HER electrocatalysts.

The development of highly efficient and durable water electrolysis catalysts plays an important role in the large‐scale applications of hydrogen energy. In this work, protrusion‐rich Cu@NiRu core@shell nanotubes are prepared by a facile wet chemistry method and used for catalyzing hydrogen evolution reaction (HER) in an alkaline environment. The protrusion‐like RuNi alloy shells with accessible channels and abundant defects possess a large surface area and can optimize the surface electronic structure through the electron transfer from Ni to Ru. Moreover, the unique 1D hollow structure can effectively stabilize RuNi alloy shell through preventing the aggregation of nanoparticles. The synthesized catalyst can achieve a current density of 10 mA cm−2 in 1.0 m KOH with an overpotential of only 22 mV and show excellent stability after 5000 cycles, which is superior to most reported Ru‐based catalysts. Density functional theory calculations illustrate that the weakened hydrogen adsorption on Ru sites induced by the alloying with Ni and active electron transfer between Ru and Ni/Cu are the keys to the much improved HER activity.
