Abstract For Metal & Metal Oxide Nanoparticles
Metal oxide nanoparticles (MO-NPs) and their solar cell applications are a globally fascinating subject that encompasses a broad range of advanced research and developing technologies. The relevance of MO-NPs as an electron transport layer (ETL) in dye-sensitized solar cells is discussed in this chapter (DSSCs). The first section of this chapter provides an overview of DSSC technology and its operation. The second section discusses potential metal oxide–based ETL materials and current methods for enhancing device performance using molecular engineering approaches. The final section discusses in depth the extremely promising titanium dioxide (TiO2)-based ETL and its ability to be adjusted, emphasising the critical role of TiO2 in the state of the art of DSSCs.
Introduction
Metal oxide nanoparticles have garnered considerable attention in electroanalysis for biomolecule identification. Significant advantages of metal oxide nanoparticles include the following:
(i)structural modifications that permit modification of lattice symmetry and cell parameters
(ii) a modification of electrochemical properties as a result of the quantum confinement effect
(iii) modification of the surface characteristics results in a significant rise in the band gap, which has an effect on the conductivity and chemical activity of the nanoparticles.
Another critical trait is their biocompatibility with enzymes used for selective detection of biomolecules.
- Numerous metal oxide nanoparticles, including NiO, ZnO, MnO2, Fe2O3, TiO2, and Co3O4, have been investigated for electrochemical detection of biomolecules. Additionally, mixed metal oxides have garnered considerable interest in this context.
- Graphene is a single atomic layer of graphite that contains a single sp2-hybridized carbon atom. It is a semiconductor with a zero band gap that has a two-dimensional (2D) layered structure with increased surface area. Graphene is frequently described as a semi-metal.
- Due to graphene’s excellent electrical, thermal, optical, and mechanical properties, it is an excellent material for electroanalytical applications.
- Graphene’s specific area is nearly double that of carbon nanotubes (2630 m2/g) (CNTs).
Worldwide, researchers have discovered the potential of graphene in its various forms, including chemically reduced graphene oxide (GO), electrochemically reduced graphene oxide (ERGO), chemical vapour deposition (CVD)-grown graphene, and functionalized graphene. Each form exhibits distinct electrochemical properties depending on the presence of functional groups or the degree of reduction.
The key to graphene’s effective utilisation is its ability to combine with other nanomaterials to create composites with the appropriate electrochemical characteristics. Metal oxide deposition onto graphene sheets (MO/Gr) exhibits a high electrochemical activity, which contributes to the improvement of sensitivity and selectivity.
Due to the synergistic impact of metal oxides and graphene, it is an ideal transducer for biomolecule detection.
Electrochemical biosensors can be broadly classified as enzymatic or nonenzymatic. In the first category, an enzyme is immobilised on the electrode surface. For instance, cholesterol is identified via cholesterol oxidase, which generates H2O2, which is amperometrically measured.
The current generated by hydrogen peroxide reduction is related to the amount of cholesterol present. In the case of nonenzymatic sensors, the biomolecule is oxidised or reduced directly on the nanomaterial-modified electrode or in the presence of mediators. In this context, the MO/Gr composite material is an excellent candidate due to its biocompatibility and high electrochemical activity.
Metal oxide nanoparticles serve as an active site, enhancing specificity and sensitivity, while graphene’s high conductivity enables rapid electron transport.
