Plasmonic nanostructures have shown immense potential in photocatalysis because of their distinct photochemical properties associated with tunable photoresponses and strong light–matter interactions. The introduction highly active sites is essential to fully exploit the plasmonic photocatalysis, considering inferior intrinsic activities typical metals. This review focuses on site-engineered enhanced photocatalytic performance, wherein are classified into four types (i.e., metallic sites, defect ligand-grafted interface sites). synergy between discussed detail after briefly introducing material synthesis characterization methods. Active can promote coupling solar energy harvested by metal catalytic reactions form local electromagnetic fields, hot carriers, photothermal heating. Moreover, efficient potentially regulates reaction pathway facilitating excited state formation reactants, changing status creating additional using photoexcited Afterward, application emerging summarized. Finally, a summary perspective existing challenges future opportunities presented. aims deliver some insights from expediting discovery high-performance photocatalysts.

The idea of activation energy appearing in a chemical reaction has been widely applied to the production biodiesel, hydrogen, oil storage, geothermal manufacturing, base liquid mechanics, emulsified, food significant renewable source, as well sewage systems. This study aims investigate resultant repercussions double diffusion, energy, Brownian motion, thermal radiation, thermophoresis, viscous dissipation, magnetic field, and Joule heating on bioconvection tangent hyperbolic nanofluid flow over vertical stretching porous surface containing microbe (gyrotactic microorganisms). fluid transport equations are converted into ordinary differential using appropriate self-similarity variables after being solved finite difference method. impacts key parameters fluid's properties depicted graphs tables. When dimensionless is higher, mass transfer rate at stretched nanomaterial sheet drops. concentration near minimizes by increasing porosity parameter value, but opposite behavior happens far from sheet.

Crystal engineering of metal oxide supports represents an emerging strategy to improve the catalytic performance noble catalysts in oxidation chlorinated volatile organic compounds (CVOCs). Herein, Pt on a TiO2 support with different crystal phases (rutile, anatase, and mixed phase (P25)) were prepared for 1,2-dichloroethane (DCE). The catalyst P25-TiO2 (Pt/TiO2-P) showed optimal activity, selectivity, stability, even under high-space velocity humidity conditions. Due strong interaction between originating from more lattice defects TiO2, Pt/TiO2-P possessed stable Pt0 Pt2+ species during DCE superior redox property, resulting high activity stability. Furthermore, abundant hydroxyl groups, which prompted removal chlorine form HCl significantly decreased selectivity vinyl chloride (VC) as main byproduct. On other hand, exhibited reaction path, groups its surface activated VC enolic species, besides oxygen rutile anatase TiO2. This work provides guidance rational design CVOCs.
