Facile and efficient 3-chlorophenol sensor development based on photolumenescent core-shell CdSe/ZnS quantum dots

“…As binding agent, it was used the 5% nafion suspended in the ethanol, which was enhanced the binding strength between GCE and CdSe/ZnS QDs. Thus, the applied nafion was improved the binding strength in addition to increase the electron transport rate of the proposed electro-chemical sensor [72][73][74][75][76][77] . To test the proposed selectivity of chemical sensor, the number of environmental contaminants with the concentration of 0.1 µM and applied potential ranging from 0 to +1.5 V were investigated in phosphate buffer solution at neutral pH.…”

“…Finally, the study indicated that trimetallic oxide nanocomposites are promising candidates for photocatalytic applications and environmental protection due to their nanostructure formation and perturbations of electronic energy levels. 51,52,[60][61][62] Anti-bacterial activity of the Ag$NiMn 2 O 4 nanocomposite…”

“…In summary, the self-assembled nanostructured material, Ag$NiMn 2 O 4 , is expected to be applied as an efficient antibacterial agent against MDR bacteria as well as an industrial sterilization system. 51,[60][61][62] Electrochemical analysis of the Ag$NiMn 2 O 4 nanomaterials/ binder/GCE Fabrication of GCE with Ag$NiMn 2 O 4 nanomaterials using Naon. The electrochemical response of the desired sensor is dependent on the precision of the fabrication of GCE with the Ag$NiMn 2 O 4 nanomaterial, and attention must be paid to the modication process of GCE.…”

Introductory Chapter: Fundamentals of Semiconductor Photocatalysis

“…For photocatalytic applications, the location of the TiO 2 nanoparticle plays an important role in the photoactivity, since various nanoparticles should be accessible for both photons and reactive molecules. The advantages of using these materials as support for TiO 2 in relation to photocatalytic processes are addressed by comparing the photocatalytic activity of TiO 2 nanoparticles deposited by different routes with TiO 2 nanoparticles on mesoporous materials [1][2][3]. Three-dimensional nanostructures have interconnected networks of bulk materials and larger accessible surface areas with respect to their lower dimensional counterparts.…”
