TL;DR: In this article, a one-step strategy to synthesize three-dimensional porous graphitic biomass carbon (PGBC) from bamboo char (BC), and studied its electrochemical performance as electrode materials for supercapacitors.

TL;DR: In this article, the positron annihilation lifetime spectroscopy (PALS) was used to characterize the oxygen vacancy associates in hydrogenation-modified TiO2 by using a positron annihilator lifetime spectrograph.

TL;DR: In this article, the P25 TiO2 nanoparticles and graphene sheets (GSs) composite were prepared from a facile thermal reaction of graphene oxide, and its microstructures and photocatalytic properties were characterized and measured using X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM), Brunauer-Emmett-Teller (BET) specific area analysis, XPS, FT-IR spectra, and ultraviolet-visible (UV-vis) diffuse reflectance spectroscopy.

TL;DR: In this paper, the influence of variant graphenes on electrochemical performance for supercapacitors was studied comparatively and systematically by using SEM, FTIR and Raman spectroscopy, cyclic voltammetry (CV), galvanostatic charge/discharge and electrochemical impedance spectrograph.

TL;DR: The results show that a PPy layer was formed on the surface of Ag-TiO2 nanofiber, which is beneficial for protecting Ag nanoparticles from being oxidized, and the PPy-Ag- TiO2 system exhibits remarkable light absorption in the visible region and high photocurrent.
