Abstract Metal organic frameworks (MOFs), which constitute a new class of porous organic–inorganic hybrid materials, have gained considerable attention in the fields electrochemical energy storage and conversion devices owing to their open topological structures, large surface areas, tunable morphologies, extreme redox activity. A synthesis protocol that comprises coprecipitation followed by controlled calcination processes design battery‐type electrode is used. This consists...
Inverted planar perovskite solar cells with PCBM ETL have poor film formation and charge transfer. Adding MgO improves photoluminescence, carrier lifetime, efficiency to 15.12%, enhances X-ray detector performance.
Hierarchical porous nanowire-like MoS2/CoNiO2 nanohybrids were synthesized via the hydrothermal process. CoNiO2 nanowires selected due to edge site, high surface/volume ratio, and superior electrochemical characteristics as backbone for decoration of layered MoS2 nanoflakes construct innovative structure hierarchical three-dimensional (3D) NWs hybrids with excellent charge accumulation efficient ion transport capabilities. Physicochemical analyses conducted on developed hybrid composite,...

This report describes the synthesis of a layered molybdenum disulfide (MoS2)–tungsten (WS2) heterostructure onto fluorine doped tin oxide covered glass substrates using combination chemical bath deposition and RF sputtering techniques. FESEM images revealed that MoS2–WS2 surface consisted cauliflower structured array grains with spherical structures. The vertically aligned atomic layers were explored by transmission electron microscopy for heterostructure. Hydrogen evolution reaction (HER)...
In view of recent environmental concerns, the need for energy security, and ever-increasing demand portable systems, scientific community is strongly motivated to develop sustainable renewable devices. Recently, hydrogen evolution reaction (HER) supercapacitors have become highly feasible technologies supporting global requirements. For this purpose, an efficient interface between carbon nanotubes (CNTs) decorated with metal carbide nanosheets (designated W2C@CNT Mo2C@CNT) developed herein...
In recent times, two-dimensional transition-metal dichalcogenides (TMDs) have become extremely attractive and proficient electrodes for dye-sensitized solar cells (DSSCs) water electrolysis hydrogen evolution as alternatives to the scarce metal platinum (Pt). The active TMD molybdenum selenide (MoSe2) tungsten disulfide (WS2) are inspiring systems owing their abundance of sulfur selenium sites, but outputs lacking due inactive basal planes ineffective transport behavior. this work, van der...
