Overall water splitting (OWS) using particulate photocatalysts is a promising and straightforward route for producing sustainable clean hydrogen. Strontium titanate (SrTiO3) well-documented photocatalyst in both one-step two-step (Z-scheme) systems presents state-of-the-art activities. Nevertheless, SrTiO3 still has inherent restraints, such as structural imperfections insufficient optical absorption ability. This critical review summarizes the recent progress photocatalytic overall...
Low-cost zirconia-toughened mullite composites were prepared from investment casting shell waste and alumina. The influence of sintering temperature on the composites' properties, including crystalline phase composition, microstructure, degrees densification, mechanical radiation shielding characteristics, was investigated. results show that higher temperature, degree densification is, improving properties composites. mullite-zirconia composite sintered at 1600 °C presents a good strength,...
In this work, polycrystalline mullite whiskers are synthesized by fluoride-assisted method from metakaolin and several aluminum-containing compounds such as γ-Al(OH)3, AlF3·3H2O, α-Al2O3 (corundum). The formation crystallization assessed both in ex situ synchrotron X-ray diffraction experiments under synthesis conditions. Polycrystalline starts to form metakaolin, Al(OH)3, AlF3·3H2O reactants at 680 °C, whereas does not even 1000 °C when corundum is used. Porous ceracmics fabricated...
All-in-one radiation shielding is an emerging concept in developing new-generation protection materials since various forms of ionizing radiation, such as neutrons and gamma rays, can occur simultaneously. In this study, we examine the ability transition metal borides to attenuate both photon particle radiation. Specifically, fourteen different (including inner borides) are selected for examination based on their thermodynamic stabilities, molecular weights, neutron capture cross-sections...
In this study, investment casting shell waste successfully utilized to produce cordierite/mullite/zircon composites. Green pellets, consisting of waste, alumina, and magnesia, were prepared sintered at temperatures between 1250 1350 °C. The influence the sintering temperature on crystalline phase composition, densification behavior, flexural strength, microstructure, radiation shielding properties composites is investigated. Phase analysis showed that characteristic cordierite peaks appear...
Abstract Melon (also known as graphitic carbon nitride, g‐C 3 N 4 ) holds promise for photocatalysis, but challenges such severe charge recombination, low oxidation potential, and sluggish exciton dissociation hinder its performance. Herein, a series of carbon‐rich, melon‐based photocatalysts are synthesized via one‐pot, temperature‐induced condensation urea with the addition trace amount citric acid. The acid enhances crystallinity, extends melon chains, increases C/N ratio, improves π–π...
