“…Unlike conventional nanofabrication techniques that require specific control of synthesis parameters such as pressure and temperature, LASiS , is a simple, nontoxic, environmentally friendly, and cost-effective technique for nanomaterial production. The underlying physicochemical processes that lead to rational synthesis of a broad range of NMs via the LASiS-GRR are presented in our previous publications. − ,− , …”

“…This includes the synthesis of intermetallic nanoalloys, and nanocomposites as electrocatalysts, as well as graphitic C-coated shell–core Al NPs as energetic materials . Moreover, LASiS-based techniques have proven successful in facile fabrication of Co-Oxide/Hydroxide nanostructures, Metal–Organic Frameworks (MOFs) and MOF-derived HNCs. , An inherent advantage of LASiS-GRR is that the high-temperature/pressure laser-induced plasma under liquid confinements can promote nonequilibrium reaction pathways with fast kinetics and quenching by the liquid environments that are otherwise not possible via traditional wet chemistry routes. To that end, LASiS-GRR has increasingly gained prominence as an attractive and expeditious method for reproducible and cost-effective synthesis of multielemental composite nanomaterials with complex structures.…”

Conversion of designer metal−organic frameworks (MOFs) into hybrid nanocomposites (HNCs) consisting of transition metal/metal oxides interfaced with carbon (C) matrices has emerged as a promising and economical alternative for the synthesis of oxygen reduction reaction (ORR) electrocatalysts, owing to their superior conductivity and high porosity. To that end, optimizing the performance of this class of material by tailoring its composition, structure, size, and morphology through an efficient synthesis route has become an active area of research. Specifically, this study employs Laser Ablation Synthesis in Solution in tandem with Galvanic Replacement Reaction (LASiS-GRR) technique as an environmentally friendly, facile, and rapid route for the design and synthesis of core−shell bimetallic zeolitic imidazolate framework (ZIF) heterostructures as bi-MOFs, and then uses pyrolytic postprocessing to yield hierarchical metal oxide/MOF-based functional HNCs as highly active ORR electrocatalysts. The LASiS-GRR technique employs high-energy laser plasma reactions as the ratecontrolling step for initiating solution-phase galvanic reactions. The one-pot, two-step process introduced in this study enables tailoring of the composition, structure, size, and morphology of composite bi-MOFs comprising Co-based MOFs encapsulated in Zn-based porous crystals (Co/ZIF-67@Zn/ZIF-8). Pyrolytic postprocessing of these core−shell bi-MOF crystals leads to the creation of hierarchical ZnO@ZIF/C HNCs with superior ORR electrocatalytic performances under alkaline conditions. Overall, these findings not only elucidate the process by which LASiS-GRR protocols are optimized to tailor the morphology, structure, and composition of complex MOF structures but also demonstrate the superior performance and stability of the ensuing postpyrolyzed ZnO@ZIF/C HNCs as nonprecious metal-based ORR electrocatalysts, when compared to commonly used Pt-and Pt-group metal (PGM)-based electrocatalysts.

“…Thus, manganese is capable of forming a wide range of MnO x oxides (MnO, Mn 2 O 3 , Mn 3 O 4 , Mn 5 O 8 , MnO 2 ) with different crystal structures, which are of interest not only in the field of electrochemical energy, but also in catalysis as well as optics and sensorics [ 20 ]. Manganese oxides both in individual form (e.g., δ-MnO 2 [ 72 ], MnO 2 [ 73 ]) and in the form of composites with carbon [ 74 , 75 ] and other [ 76 ] materials are actively used as component in functional inks for printing MSCs electrodes. Thus, in a work by Wang et al [ 72 ], interdigital electrode structures were deposited using ink based on δ-MnO 2 nanosheets (lateral size 89 nm, thickness—about 1 nm) in a mixture (1:10) of propylene glycol and water by inkjet printing on the surface of polyimide film (thickness—120 μm).…”

The development of scientific and technological foundations for the creation of high-performance energy storage devices is becoming increasingly important due to the rapid development of microelectronics, including flexible and wearable microelectronics. Supercapacitors are indispensable devices for the power supply of systems requiring high power, high charging-discharging rates, cyclic stability, and long service life and a wide range of operating temperatures (from −40 to 70 °C). The use of printing technologies gives an opportunity to move the production of such devices to a new level due to the possibility of the automated formation of micro-supercapacitors (including flexible, stretchable, wearable) with the required type of geometric implementation, to reduce time and labour costs for their creation, and to expand the prospects of their commercialization and widespread use. Within the framework of this review, we have focused on the consideration of the key commonly used supercapacitor electrode materials and highlighted examples of their successful printing in the process of assembling miniature energy storage devices.
