We discovered that chemically reduced graphene oxide, with an ID/IG >1.4 (defective to graphite) can effectively activate peroxymonosulfate (PMS) produce active sulfate radicals. The produced radicals (SO4•—) are powerful oxidizing species a high oxidative potential (2.5–3.1 vs 2.7 V of hydroxyl radicals), and decompose various aqueous contaminants. Graphene demonstrated higher activity than several carbon allotropes, such as activated (AC), graphite powder (GP), oxide (GO), multiwall...

Activation of reduced graphene oxide (RGO) using CO2 to obtain highly porous and metal-free carbonaceous materials for adsorption catalysis was investigated. A facile one-pot thermal process can simultaneously reduce produce activated RGO without introducing any solid or aqueous activation agent. This significantly increase the specific surface area (SSA) from 200 higher than 1200 m2 g−1, obtained were proven be effective adsorptive removal both anionic (phenol) cationic (methylene blue, MB)...

Photocatalysis shows a great potential for N2 fixation to NH3 under mild conditions, which intrigues increasing research attention in recent decades. To this end, the design of efficient photocatalysts is key. Herein, we report synthesis single atom Ru decorated TiO2 nanosheets rich oxygen vacancies. Single sites greatly promoted photoreduction aqueous NH3, affording an formation rate 56.3 μg/h/gcat. We found that isolated atoms likely weakened hydrogen evolution, absorption N2, and also...

Nanoscaled zerovalent iron (ZVI) encapsulated in carbon spheres (nano-Fe⁰@CS) were prepared via a hydrothermal carbonization method, using glucose and iron(III) nitrate as precursors. The properties of the nano-Fe⁰@CS investigated by X-ray diffraction (XRD), thermogravimetric analysis-differential scanning calorimetry (TGA-DSC), Fourier transform infrared spectroscopy (FTIR), electron microscopy (SEM), transmission (TEM), nitrogen adsorption/desorption isotherms. Nano-Fe⁰@CS was...
