Graphene‐based nanocomposites with inorganic (metal and metal oxide) nanoparticles leads to materials with high catalytic activity for a variety of chemical transformations. Graphene and its derivatives such as graphene oxide, highly reduced graphene oxide, or nitrogen‐doped graphene are excellent support materials due to their high surface area, their extended π‐system, and variable functionalities for effective chemical interactions to fabricate nanocomposites. The ability to fine‐tune the surface composition for desired functionalities enhances the versatility of graphene‐based nanocomposites in catalysis. This review summarizes the preparation of graphene/inorganic NPs based nanocomposites and their use in catalytic applications. We discuss the large‐scale synthesis of graphene‐based nanomaterials. We have also highlighted the interfacial electronic communication between graphene/inorganic nanoparticles and other factors resulting in increased catalytic efficiencies.

“…However, the growing trend of Hybrid lithium-ion capacitors is seriously impeded due to rising lithium resources price and the low geographical limitation [15][16][17][18][19]. Therefore, metal-ion capacitors composed of abundant elements, in other words, new-type energy storage devices, including sodium [20][21][22][23][24], potassium [6,[25][26][27]] magnesium [28][29][30][31], aluminum [15,[28][29][30][31][32][33][34][35] and zinc [36][37][38][39], are essential for alternatives to HLICs. It is well established that sodium is similar to lithium in chemical properties, indicating the experience obtained from the HLICs researches can be applied to hybrid sodium ion capacitors [40][41][42].…”

The development of electrochemical energy storage devices has a decisive impact on clean renewable energy. Herein, novel ultrafast rechargeable hybrid sodium dual-ion capacitors (HSDICs) were designed by using ultrathin carbon film (UCF) as the cathode material. The UCF is synthesized by a simple low temperature catalytic route followed by an acid leaching process. UCF owns a large adsorption interface and number of additional active sites, which is due to the nitrogen doping. In addition, there exists several short-range order carbons on the surface of UCF, which are beneficial for anionic storage. An ultrafast rechargeable remarkable performance, remarkable anion hybrid storage capability and outstanding structure stability is fully tapped employing UCF as cathode for HSDICs. The electrochemical performance of UCF in a half-cell system at the operating voltage between 1.0 and 4.8 V, achieving an admirable specific discharge capacity of 358.52 mAh·g−1 at 500 mA·g−1, and a high capacity retention ratio of 98.42% after cycling 2500 times at 1000 mA·g−1, respectively. Besides, with the support of ex-situ TEM and EDS mapping, the structural stability principle and anionic hybrid storage mechanism of UCF electrode are investigated in depth. In the full-cell system, HSDICs with the UCF as cathode and hard carbon as anode also presents a super-long cycle stability (80.62% capacity retention ratio after cycling 1300 times at 1000 mA·g−1).

Lithium‐selenium (Li‐Se) batteries have attracted ever‐increasing attention owing to high volumetric capacity comparable to lithium‐sulfur batteries and excellent electronic conductivity of Se. However, unsatisfactory energy density and cycling life of Li‐Se batteries mainly caused by low utilization of Se and shuttle effect of polyselenides (PSes) seriously prevent their commercial applications. Herein, this work systematically reviews the recent advances of the state‐of‐the‐art cathodes and interlayers in high‐performance Li‐Se batteries. First, the fundamental chemistries of Li‐Se batteries are introduced in terms of various Se precursors and electrochemical behaviors. Second, the main strategies in cathodes and interlayers for addressing poor conductivity of Se and shuttle effects of PSes are summarized as three‐dimensional conductive skeletons for Se, physical confinement of Se, chemisorption and catalytic conversion of PSes, and free‐standing interlayers and interlayers on separators. Further, the synthesis strategies and enhanced electrochemical performance are specially exemplified to highlight the possible enlightenments for constructing advanced cathodes and interlayers. Finally, the future challenges and perspectives of advanced cathodes and interlayers in high‐performance Li‐Se batteries are briefly discussed.
