Ag nanowire@TiO2 (Ag NW@TiO2) heterostructures with core–shell, necklace‐like, and particle‐decorated morphologies were fabricated to investigate the evolution of the photocatalytic properties. The deposition of the TiO2 phase on the surface of the Ag NWs was achieved through a solvothermal method. Thioglycolic acid (TGA) not only solves the tricky issue of substantial lattice mismatch between the Ag NW core and TiO2 shell, but also plays an important role in precisely controlling how the TiO2 is coated on the Ag NW surface. H2O molecules affect the deposition of the TiO2 phase on the Ag NWs. The photocatalytic activity of the Ag NW@TiO2 heterostructures with different morphologies was evaluated by degradation of methyl orange. The molar ratio of TiO2 to Ag is crucial for the photocatalytic activity, and the Ag NW@TiO2 sample with core–shell structure exhibits an excellent performance compared with the others, owing to the TiO2 phase being densely attached to the Ag NW surface, which forms a well‐developed combined interface.

“…The Hao group attempted to construct active sites on the graphene surface and obtained amino-functionalized graphene (AFG). [190] The DSC using the AFG CE obtained a high PCE of 7.39%, significantly higher than that of the DSC using the pristine graphene CE (4.33%). In addition to the morphology and specific structure design, the effects attributed to the doping of heteroatoms (such as Adv.…”

Developing highly effective and stable counter electrode (CE) materials to replace rare and expensive noble metals for dye‐sensitized and perovskite solar cells (DSC and PSC) is a research hotspot. Carbon materials are identified as the most qualified noble metal‐free CEs for the commercialization of the two photovoltaic devices due to their merits of low cost, excellent activity, and superior stability. Herein, carbonaceous CE materials are reviewed extensively with respect to the two devices. For DSC, a classified discussion according to the morphology is presented because electrode properties are closely related to the specific porosity or nanostructure of carbon materials. The pivotal factors influencing the catalytic behavior of carbon CEs are also discussed. For PSC, an overview of the new carbon CE materials is addressed comprehensively. Moreover, the modification techniques to improve the interfacial contact between the perovskite and carbon layers, aiming to enhance the photovoltaic performance, are also demonstrated. Finally, the development directions, main challenges, and coping approaches with respect to the carbon CE in DSC and PSC are stated.

In this study, graphene oxide‐iron oxide‐polypyrrole (GO‐Fe3O4‐PPy) ternary nanocomposites having high photothermal activity and stability are synthesized and analyzed using ultraviolet–visible (UV–Vis) spectroscopy, Fourier transform infrared (FTIR), X‐ray diffraction spectroscopy (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high‐resolution transmission electron microscopy (HRTEM), and magnetic hysteresis measurement (VSM). The effect of power density (1.5–2.5 W cm−2), concentration (0.01–0.2 mg mL−1), and component composition of nanocomposites on the photothermal properties in the near‐infrared (NIR) region (808 nm) is examined. The results show that superparamagnetic GO‐Fe3O4‐PPy ternary nanocomposite exhibits excellent photothermal performance. The temperature reaches to 55.5, 72.3, and 83.1 °C under the irradiation of the 808 nm NIR laser at 1.5, 2.0—, and 2.5 W cm−2 of power density for 10 min at 0.1 mg mL−1 photothermal therapy (PTT) agent, respectively, and moreover it has excellent photothermal stability. In summary, it is concluded that synthesized nanocomposites potentially may be used in simultaneous magnetic field‐guided treatments. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.
