Fur-Imine-Functionalized Graphene Oxide-Immobilized Copper Oxide Nanoparticle Catalyst for the Synthesis of Xanthene Derivatives

“…21−23 GO and its nanocomposites have a wide range of applications as catalysts, 24−29 photocatalysts, 30−32 energy storage, 33 sensors, 34−36 hydrogen storage, 37 drug delivery, 38 biomedical devices, 39 super-capacitors, 40,41 and waste water treatment. 42,43 In the backdrop of their excellent synergistic action, GO-based nanocatalysts are rationalized using nanoparticles (NPs) adorning its surface for them to be used as heterogeneous catalysts to overcome different economic and environmental problems. 44 However, metal NPs over a solid support of GO are unstable because of their high surface energy, which leads to irreversible agglomeration and thus reduces the catalytic activity.…”

“…Therefore, a heterogeneous nanocatalyst can address this problem as they can be easily separated by different filtrations or centrifugation techniques. Graphene, an allotrope of carbon, is one of the extensively investigated 2D materials as the catalyst or support to various metal nanocatalysts exhibiting excellent catalytic activity for different types of organic transformations. , Graphene and graphene oxide (GO) have excellent mechanical strength, electron transport properties, large specific surface area, good adsorption capacity, high chemical, and thermal stability. − GO and its nanocomposites have a wide range of applications as catalysts, − photocatalysts, − energy storage, sensors, − hydrogen storage, drug delivery, biomedical devices, super-capacitors, , and waste water treatment. , In the backdrop of their excellent synergistic action, GO-based nanocatalysts are rationalized using nanoparticles (NPs) adorning its surface for them to be used as heterogeneous catalysts to overcome different economic and environmental problems .

Dopant engineering for ZnO electron transport layer towards efficient perovskite solar cells

“…It is used as an electrode, and the burning rate of propellants can also be increased by lanthanum oxide. 139,140 Furthermore, previous research suggested that adding a small amount of La to doped ZnO can signicantly improve its photocatalytic properties by: (i) enhancing charge separation; (ii) increasing surface area and active sites; (iii) shiing in band-edge positions; and (iv) reducing charge carrier recombination, [141][142][143] as discussed in Section 5 regarding 2. The utilization of La-doped ZnO extends beyond the realm of solar cell applications.…”

Graphene Oxide-Based Nanohybrids as Pesticide Biosensors: Latest Developments

“…Similarly, in graphene oxide/polymer nanohybrids, surface functionalities present on GO surface groups can assist the combination of GO with polymers or synthesis of the polymer by different polymerization techniques [87,88]. A typical modification strategy includes covalent bonding, that is, "Grafting to" and "Grafting from" approaches, whereas noncovalent modification includes π-π stacking, electrostatic interaction, and hydrogen bonding [89][90][91].…”
