Hydrogen carriers are one of the keys to success using hydrogen as an energy vector. Indeed, sustainable production exploits excess renewable sources, after which temporary storage is required. The conventional approaches and transport compressed (CH2) liquefied (LH2), require severe operating conditions related pressure (300–700 bar) temperature (T < −252 °C), respectively. To overcome these issues, have hindered market penetration, several alternatives been proposed in last few decades. In this review, most promising (ammonia, methanol, liquid organic carriers, metal hydrides) considered, main stages their supply chain (production, storage, transportation, H2 release, recyclability) described critically analyzed, focusing on latest results available literature, highlighting our current concern. section reviews recent techno-economic analyses drive selection carrier systems constraints that must be considered. analyzed show how a multiparametric function, it depends technological factors well international policies regulations.

Abstract Recently, the development of heterogeneous nanocatalytic systems using solid supports has been gaining importance due to some advantages such as easy handling, high thermal stability, efficiency, reusability, and so on. Therefore, design catalyst for preparation stable catalytic is great importance. In this work, Schiff base-modified ZnO particles have developed (ZnO–Scb) a novel support. A nanocatalyst system then prepared by immobilizing palladium nanoparticles (Pd NPs) on ZnO-Scb surface The resulting (Pd–ZnO–Scb) structure characterized different analytical techniques (FT-IR, XRD, TEM, FE-SEM, elemental mapping EDS) used catalyze Heck coupling reactions 4-nitrophenol (4-NP) reduction. Test results revealed that Pd–ZnO–Scb could effectively couple various aryl halides with styrene in yields up 98% short reaction times. was also efficiently complete 4-NP reduction within 135 s at room temperature. Additionally, it found more effective than other reported catalysts reaction. Moreover, recycling tests indicated be easily isolated from medium reused seven consecutive runs while retaining its nanostructure.

The shortage of water resources has caused extensive research to be conducted in this field develop effective, rapid, and affordable wastewater treatment methods. For the wastewater, modern oxidation techniques are desirable due their excellent performance simplicity implementation. In project, wet impregnation hydrothermal technique were applied synthesize a modified catalyst. Different analysis methods used determine its characteristics, including XRD, BET, FT-IR, NH3−TPD, FE-SEM. catalyst features spherical shape, large surface area, high crystallinity, uniform active phase dispersion. order eliminate methylene blue dye as modeling effluent, catalyst’s was examined heterogeneous quasi-electro-Fenton (EF) reaction. impact various such concentration reaction medium, solution pH, current intensity between two electrodes, elucidated. According results, best operational circumstances included pH level 2, 0.15 g/L, 150 mA, resulting greatest elimination efficiency 101%. stable during three consecutive tests. A pseudo-first-order model for reaction’s kinetics developed, which showed acceptable agreement with experimental results. This study’s findings help clarify how well zeolite functions pseudo-EF results revealed method’s potential implemented treatment.
