“…CNTs are carbon macromolecules that have narrow distributions of pore volumes for efficient gas adsorption [96][97][98][99]. Thus, CNTs were obtained in two different primary species characterized by their wall structures as single-walled nanotubes (SWNTs) or multi-walled nanotubes (MWNTs) [100][101][102][103][104].…”

With the rapid growth in demand for effective and renewable energy, the hydrogen era has begun. To meet commercial requirements, efficient hydrogen storage techniques are required. So far, four techniques have been suggested for hydrogen storage: compressed storage, hydrogen liquefaction, chemical absorption, and physical adsorption. Currently, high-pressure compressed tanks are used in the industry; however, certain limitations such as high costs, safety concerns, undesirable amounts of occupied space, and low storage capacities are still challenges. Physical hydrogen adsorption is one of the most promising techniques; it uses porous adsorbents, which have material benefits such as low costs, high storage densities, and fast charging–discharging kinetics. During adsorption on material surfaces, hydrogen molecules weakly adsorb at the surface of adsorbents via long-range dispersion forces. The largest challenge in the hydrogen era is the development of progressive materials for efficient hydrogen storage. In designing efficient adsorbents, understanding interfacial interactions between hydrogen molecules and porous material surfaces is important. In this review, we briefly summarize a hydrogen storage technique based on US DOE classifications and examine hydrogen storage targets for feasible commercialization. We also address recent trends in the development of hydrogen storage materials. Lastly, we propose spillover mechanisms for efficient hydrogen storage using solid-state adsorbents.

“…The surface properties, wide bandgap, and high exciton bond energy cause attractive electrochemical hydrogen energy storage characteristics in ZnO [50] , [51] . The potential of ZnO in different conditions (e.g., ZnO and Mg-doped ZnO [52] , change in weight percentage of Mg-doped ZnO nanowires [53] , ZnO in various morphologies [54] , ZnO@f-MWCNTs [55] , ZnO-MWCNTs [56] , Al and Mg-doped ZnO nanofibers [57] , LiBH 4 @x ZnO/ZnCo 2 O 4 [58] , ZnO-HMD@ZnO-Fe/Cu core–shell [51] , Mo/DAN/ZnO [59] ) have been tested in hydrogen storage. Inspired by these investigations, can be designed new structures and evaluated in hydrogen energy storage.…”

“…Carbon nanotubes (CNTs) have large specific surface areas, highly porous and hollow structures, low density, excellent mechanical properties, good thermal stability, tunable surface chemistry, non‐corrosive properties, and other distinctive chemical and physical properties. Thus, CNTs have been widely used in many fields as hydrogen storage materials, 11–13 adsorption materials, 14,15 nano‐filling materials, 16 and electrode materials 17 . Recently, a large number of studies have confirmed that CNTs show strong potential as high‐efficiency adsorbents for the adsorption and degradation of various pollutants such as metallic ions, 18–21 organic dyes, 22,23 and other harmful organic compounds 24 .…”

In this study, the adsorption of the antibiotic compound tetracycline (TC) from aquaculture wastewater was investigated using lanthanum-modified carbon nanotubes (La-CNTs) prepared by impregnation method. The composition and morphology of La-CNTs were characterized by EDS, XRD, and BET analysis. Single-factor experiments were performed to investigate their effect on the adsorption of TC by La-CNTs. The adsorption kinetics and adsorption isotherms indicated that the pseudo-second-order kinetic model and Langmuir adsorption isotherm equation adequately described the adsorption behavior of La-CNTs. Moreover, the maximum adsorption capacity (Q m ) was 93.46 mg/g. The thermodynamics studies indicated that adsorption of TC by La-CNTs were endothermic and spontaneous respectively.Further, the adsorption force of La-CNTs on TC could be attributed to van der Waals force, π-π adsorbate-adsorbent interaction and electrostatic interaction. Based on these experimental results, this novel composite material shows good potential application value for the removal of TC from aquaculture wastewater.
