TL;DR: In this article, a straightforward strategy was designed for the fabrication of magnetically separable CoFe2O4-graphene photocatalysts with differing graphene content, and the significant enhancement in photoactivity under visible-light irradiation can be ascribed to reduction of graphene oxide, because the photogenerated electrons of CoFeO4 can transfer easily from the conduction band to the reduced graphene oxide effectively preventing a direct recombination of electrons and holes.

TL;DR: In this paper, a carbon black supported nano-Ni catalyst was used for hydrogenation of nitrophenols even at 30 degrees C. The high performance obtained by the Ni-based catalyst can be attributed to the specific characteristics of the nanostructure of the catalyst and the synergistic effect of nanoNi and carbon black, including plenty of oxygen-containing groups of carbon black for anchoring Ni atoms.

TL;DR: In this paper, a BiVO4-graphene photocatalyst was prepared by a facile one-step hydrothermal method and characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman Spectroscopy, XPS, and transmission electron microscopy (TEM) techniques.

TL;DR: In this article, a straightforward strategy is designed for the fabrication of CuFe2O4-graphene heteroarchitecture via a one-step hydrothermal route to allow multifunctional properties, i.e., magnetic cycling, high photocatalytic activity under visible light irradiation, and excellent electrochemical behaviors for use as the anode in lithium-ion batteries (LIBs).

TL;DR: In this article, a cobalt ferrite-polyaniline photocatalyst is successfully prepared by in situ oxidative polymerization, and a significant adsorption can be observed in the case of the anionic dyes and neutral dyes because the negatively charged groups or the electron-rich groups of these dyes undergo chemical interactions with the positively charged backbone of PANI.
