In this work, we report a one-step synthesis of ternary Z-scheme Co(OH)2/CeO2-g-C3N4 (CoCe-CN) heterostructure via hydrothermal method. Owing to the modification Co(OH)2 and CeO2, existence as an electron acceptor-donor center between CeO2 g-C3N4 accelerates transfer provides extra OH- reaction pathway for photocatalytic oxidation NO. As result, 50CoCe-CN (Co Ce accounting 25% mass ratio separately) achieved 53.5% conversion efficiency NO at 600 ppb concentration, which is 1.82 times that under visible light. The results DFT analysis element distribution cobalt ceria provide convincing evidence supporting novel multi-layer structure in CoCe-CN photocatalyst. This involves loading on surface, co-catalyst introduced realizes synergy further improve properties. higher efficiencies observed photocatalysts compared those containing only (Co-CN) or (Ce-CN) synergistic effect these two elements. work demonstrates more efficient effective system, with greater practical potential

The rapidly increasing population, industrial emissions, vehicle exhaust and open burning of garbage waste are the main cause pollutants which regularly deteriorate natural environmental conditions. continuous monitoring these is necessary to prevent deterioration. Various types instruments available monitor pollutes harmful gases, time consuming, expensive rarely used for in real-time areas. In recent years, scientific community has carried out extensive research on ideal sensor from theory practice. There different materials such as carbon nanotubes (CNTs), Graphene (G), metal/metal oxide nanoparticles, two dimensional (2D) nanomaterials hybrid nanostructures, have been widely investigated sensing gas sensors. So keeping aforesaid mind, this review article focuses emerging technologies that can identify applications.

Semiconducting metal oxide-based gas sensors have inadequate selectivity as they are responsive toward a variety of gases. Here, we report the implementation sensing kinetic analysis sensor to identify tested volatile organic compounds (VOCs) (2-propanol, formaldehyde, methanol, and toluene) precisely. A single chemiresistive was employed having tin hollow spheres material, which were obtained by chemical synthesis. The measurements conducted in dynamic manner where displayed excellent response with high sensitivity. Eley-Rideal model adopted obtain properties phenomenon through theoretical fitting transient curves their corresponding parameters. calculated characteristic further examined discriminate among different VOCs. approach using for multiple discrimination is an attractive solution mitigate problem cross-sensitivity resistive sensors.

Aims: Indoor air quality (IAQ) has attracted increased attention with the emergence of COVID-19. Ventilation is perhaps area in which most changes have been proposed response to emergency caused by this virus. However, other strategies are possible, such as source control and extraction pollutants. The latter incorporates clean technologies, an emergent respect IAQ. Method: Various treatment technologies can be used contaminants, reviewed discussed work, including physicochemical (e.g., filtration, adsorption, UV-photocatalytic oxidation, ultraviolet disinfection ionization) biological plant purification methods microalgae-based methods). Results interpretation: This work reviews currently available solutions for “cleaning” indoor air, a focus on their advantages disadvantages. One common problems emission pollutants that sometimes more dangerous human health than those were developed remove. Another aspect consider limitation each technology relation type need removed. Each investigated works well family similar characteristics, but it not applicable all pollutant types. Thus, optimal solution may involve use combination extend scope application, addition development new materials, example, through nanotechnology.
