Photoelectrochemical and photocatalytic properties of Fe@ZnSQDs/TiO2 nanocomposites for degradation of different chromophoric organic pollutants in aqueous suspension

An overview of surface-enhanced Raman scattering substrates by pulsed laser deposition technique: fundamentals and applications

“…Thus, it is very important to develop the corresponding analytical techniques for monitoring the trace pollutants. A number of analytical techniques, including spectrophotometry [ 147 – 149 ], fluorescence [ 150 – 152 ], chromatography [ 153 , 154 ], and electrochemical methods [ 155 , 156 ] have been reported. However, the complicated instruments, complex sampling processes, and insufficient recognition capability restrict their applications.…”

Transition Metal Engineering of Molybdenum Disulfide Nanozyme for Biomimicking Anti-Biofouling in Seawater

“…38−44 Among them, heteroatom engineering is an appealing pathway to enhance the redox ability of MoS 2 . 45,46 We therefore anticipate that the metallic heteroatom-doped MoS enrich our understanding on the relationship between the foreign metallic doping and biological mimicking reaction kinetically.…”

“…Layered transition metal dichalcogenides have demonstrated superior performance in many fields, such as solid lubricants, energy devices, petrochemical catalysis, and so forth, due to their physicochemical diversity, low cost, and chemical stability. − In view of these advantages, MoS 2 has been explored as a valuable nanozyme that exhibits multiple enzyme-mimicking activities, such as superoxide dismutases, catalases, and peroxidases, in combating oxidative stress and disinfecting drug-resistant bacteria. , Unfortunately, MoS 2 exhibited very poor haloperoxidase-mimicking activity, as experimentally revealed in this work. In fact, for a variety of catalytic applications, experimental and computational results have confirmed that the activity origin of layered MoS 2 could be attributed to the highly exposed edge sites. − From this perspective, significant research efforts are being conducted to regulate the catalytic performance of MoS 2 , including dimensional control, metallic and non-metallic doping, and defect engineering. − Among them, heteroatom engineering is an appealing pathway to enhance the redox ability of MoS 2 . , We therefore anticipate that the metallic heteroatom-doped MoS 2 could enhance haloperoxidase-mimicking activity and enrich our understanding on the relationship between the foreign metallic doping and biological mimicking reaction kinetically.…”

A Visible Light Driven Photoelectrochemical Chloramphenicol Aptasensor Based on a Gold Nanoparticle-Functionalized 3D Flower-like MoS2/TiO2 Heterostructure

“…Photoelectrochemical (PEC) bioanalysis is a unique sensing strategy that combines the advantages of electrochemistry and photochemistry. − In particular, because of different transducing modality used for excitation source (light) and readout signal (photocurrent), visible light driven PEC bioanalysis shows more unique advantages than traditional electrochemical detection, including easy operation, high sensitivity, and facile instrument. , Unfortunately, the selectivity of PEC bioanalysis is relatively weak because of the fact that most substances will be easily oxidized by powerful oxidants generated by photoirradiation, including hydroxyl (HO·), superoxide (O 2 · – ), which limit the practical application of the PEC sensors . Therefore, the sensing platforms are often combined with recognition elements to enhance the recognition ability of target molecules.…”
