“…This type of material consists of ammonia, formic acid, boron‐based hydrides, metal hydrides, and complex hydrides . Storing hydrogen under electrochemical conditions is primarily achieved via cyclic voltammetry (CV), and the amount of absorbed hydrogen is related to the value of applied potential . In case of hydrogen storage, a composite system based on the integration of several remarkable materials is likely ideal.…”

“…19,28 During this process, a polarized electrode surface splits water into hydrogen, and then, the produced hydrogen is absorbed onto the surface. 19 Conductive polymers (CPs), especially polyaniline (PANI), polythiophene (PTh), and polypyrrole (PPy), are brought into sharp focus in the domain of electrochemistry due to their intrinsic properties, including considerable adhesion, hydrophilic properties, conductivity, stability, and facile synthesis. 29 Conducting polymers/composites are used as supporting films for metal catalysts, which may offer more electrocatalytic sites than bare metal electrodes due to their roughened surfaces and three-dimensional repartition of the reactive sites due to the favorable dispersibility of a metal catalyst in a polymer matrix.…”

Summary A wide compositional range of Pd‐Ni/Cd on polypyrrole (PPy)‐modified Ti plates (Pd‐Ni/Cd/PPy/Ti) was fabricated via electrochemical deposition. The hydrogen absorption properties of the prepared Pd‐Ni/Cd/PPy/Ti electrodes were evaluated using cyclic voltammetry and chronoamperometry in acidic media. The optimal Pd36‐Ni7/Cd57/PPy/Ti electrode achieved a hydrogen storage capacity of 331.3 mC cm−2 mg−1 and an H/Pd ratio of 0.77. The enhancement of the hydrogen storage was attributed to a synergistic effect between the Pd‐Ni/Cd catalysts. The surface morphology, crystallinity, and chemical composition of the Pd‐Ni/Cd/PPy/Ti electrode were characterized using scanning electron microscope (SEM), X‐ray diffraction (XRD), and X‐ray photoelectron spectroscopy (XPS), respectively. Hydrogen spillover occurred on the trimetallic catalysts, and secondary hydrogen spillover occurred on the PPy/Ti support. The enhanced hydrogen sorption capacity was due to both the synergistic effect of the trimetallic catalysts and the assistance of PPy, making Pd‐Ni/Cd/PPy/Ti a promising hydrogen storage material.

“…Polystyrene (PS) is an ideal candidate material because of the easy fabricating process of its microspheres. However, the hydrogen barrier property of PS is very poor [6]. Therefore, a barrier layer should be added on the surface of PS to prevent the leakage of fuel gas from the microspheres.…”

The ozonization modification of polystyrene (PS) was conducted in acidic condition to enhance the interfacial interaction between PS and polyvinyl alcohol (PVA). Infrared spectra results revealed that the carbonyl and hydroxyl groups were successfully introduced to the PS film by ozonization. The hydrophobic PS was turned to be hydrophilic to some extent by contact angle experiment, which led to the enhancement of interfacial adhesion between PS and PVA. In addition, the adsorption of PS to PVA was also improved. Nano indenter measurement indicated the interfacial interaction between PS film and PVA film was obviously enhanced by 40% after ozonization at room temperature for 2 h in acidic condition, which will benefit for fabricating laser inertial confinement fusion container.

It is estimated that all fossil fuels will be depleted by 2060 if we continue to use them at the present rate. Therefore, there is an unmet need for an alternative source of energy with high calorific value. In this regard, hydrogen is considered the best alternative renewable fuel that could be used in practical conditions. Accordingly, researchers are looking for an ideal hydrogen storage system under ambient conditions for feasible applications. In many respects, carbon‐based sorbents have emerged as the best possible hydrogen storage media. These carbon‐based sorbents are cost‐effective, eco‐friendly, and readily available. In this Review, the present status of carbon‐based materials in promoting solid‐state hydrogen storage technologies at the operating temperature and pressure was reported. Experimental studies have shown that some carbon‐based materials such as mesoporous graphene and doped carbon nanotubes may have hydrogen storage uptake of 3–7 wt %, while some theoretical studies have predicted up to 13.79 wt % of hydrogen uptake at ambient conditions. Also, it was found that different methods used for carbon materials synthesis played a vital role in hydrogen storage performance. Eventually, this Review will be helpful to the scientific community for finding the competent material and methodology to investigate the existing hydrogen uptake issues at operating conditions.
