Designing of Nanomaterials-Based Enzymatic Biosensors: Synthesis, Properties, and Applications

“…Over the past few decades, nanostructured materials have considerably changed the analytical and bioanalytical sciences [75]. Nanomaterials have been showing a fundamental role in the expansion of this science to the most diverse industrial fields, such as fuel, energy storage, energy conversion, nanocatalysis, integrated catalysis, industrial waste treatment, biomedicine, food, and bioengineering, among others [61,62,[75][76][77][78][79][80][81][82][83][84][85][86][87][88] (Figure 3). nanocatalysis, integrated catalysis, industrial waste treatment, biomedicin bioengineering, among others [61,62,[75][76][77][78][79][80][81][82][83][84][85][86][87][88] (Figure 3).…”

Among organic nanomaterials, nanotubes stand out due to their high resistance and capillarity, and their unique electronic structure [73].…”

Synthesis, Characterization, and Photocatalytic Performance of ZnO–Graphene Nanocomposites: A Review

“…Graphene in photocatalysis: a review 2016 [33] Review on ZnO hybrid photocatalyst: impact on photocatalytic activities of water pollutant degradation 2016 [34] Advancements in the zinc oxide nanomaterials for efficient photocatalysis 2017 [35] The effect of ZnO-based carbonaceous materials for degradation of benzoic pollutants: a review 2019 [31] Progress in Graphene/Metal Oxide Composite Photocatalysts for Degradation of Organic Pollutants 2020 [36] Nanoscale zinc oxide-based heterojunctions as visible light active photocatalysts for hydrogen energy and environmental remediation 2020 [25] Advances and Challenges in Developing Efficient Graphene Oxide-Based ZnO Photocatalysts for Dye Photo-Oxidation 2020 [32] State of the art on the photocatalytic applications of graphene-based nanostructures: From elimination of hazardous pollutants to disinfection and fuel generation 2020 [27] An overview of graphene oxide supported semiconductors based photocatalysts: Properties, synthesis, and photocatalytic applications 2020 [37] The present work aims to address issues related to the effect of the type of ZnO structure (0D, 1D, 2D, 3D) linked mainly to graphene oxide (GO) and reduced graphene oxide (rGO), updating (2016-2020) the relevant aspects of the synthesis, characterization and photocatalytic properties. Indeed, there are currently significant advances with the use of ternary composites such as ZnO-metal-graphene or ZnO-semiconductor-graphene or using other types of carbonaceous materials, e.g., 3D graphene, graphene Q-dots, graphitic carbon nitride, among others [36]; nevertheless, they are outside the scope of this review.…”

“…3%). To a lesser extent, these composites have been tested in the photocatalytic reduction of CO 2 towards obtaining solar fuels [27,150] (ca. 2%).…”

“…Graphene oxide (GO) and reduced graphene oxide (rGO) are widely used derivatives of graphene (see Figure 4), both in their pristine and composite form. Their main applications are supercapacitors, photovoltaics, adsorbents, filtration membrane, sensors, lithium-ion batteries, anti-corrosion materials, sodium-ion batteries, and drug delivery solar cells, and photocatalysis [27]. GO, as a product of delamination of oxidized graphite, contains numerous oxygen functional groups, structural defects, and chemically bonded impurities.…”
