In this paper, a 5,10,15,20-tetrakis(4-(hydroxyl)phenyl) porphyrin (TPPH) noncovalently functionalized reduced graphene oxide (RGO) nanohybrid has been facilely synthesized by immobilizing TPPH on RGO nanosheets. This was characterized atomic force microscopy (AFM), transmission electron (TEM), and UV–vis spectra, which demonstrated that the molecule attached surface of nanosheet. The results fluorescence quenching photocurrent enhancement TPPH–RGO exhibit fast electrons transfer from...
In this paper, we report the synthesis, characterization, and photocatalysis of a novel composite, composed high-ordered mesoporous WO3 (m-WO3) reduced graphene oxide (RGO). The composite was systematically characterized by X-ray diffraction, transmission electron microscopy, Raman spectroscopy, Fourier transform infrared N2 adsorption–desorption UV-visible diffuse reflectance spectroscopy techniques. superior contact between two moieties in composites facilitates charge carrier separation...
Herein, we report an efficient photocatalytic hydrogen evolution system based on Ru-tris(dicarboxybipyridine)–reduced graphene oxide (Ru(dcbpy)3–RGO) hybrid. AFM images and UV-vis spectra validate Ru(dcbpy)3 functionalized RGO via noncovalent interactions. Fluorescence Raman suggest that acts as electron donor serves acceptor in the hybridized species. Moreover, photocurrent experiment further confirms photoelectrons transfer from to nanosheets then flow deposited Pt nanoparticles...
Structure inherited synthesis of N-doped highly ordered mesoporous Nb<sub>2</sub>O<sub>5</sub>as an efficient and stable visible-light-driven photocatalyst for hydrogen evolution.
Herein, a novel non‐noble metal photocatalyst Co 3 S 4 /MnCdS (CS/MCS) for highly efficient hydrogen evolution has been successfully prepared through simple hydrothermal method. Due to the work function difference between CS and MCS, an interfacial internal electric field is formed at interface region of CS/MCS when two components are in intimate contact. Upon light illumination, photogenerated charge carriers transfer S‐scheme‐like type CoS bonds. This facilitates separation diffusion...
A novel composite composed of TiSi(2), graphene and RuO(2) nanoparticles was fabricated by a one-pot deposition method using reduced oxide (RGO) as supporting matrix RuCl(3) the precursor. The resulting RuO(2)/TiSi(2)/RGO characterized scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectra, photoelectron spectroscopy, UV-vis diffuse reflectance photoelectrical response electrochemical impedance spectra. results indicated that three components in were effectively...
A novel nanohybrid composed of bipyridine ruthenium complex ((2,2′-bipyridyl)-4-pyridyl-chloro-ruthenium(II), Ru(bpy)2(py)Cl), covalently functionalized graphene (Ru(bpy)2(py)Cl/G), has been synthesized successfully via coordination Ru(bpy)2Cl2 with pyridine (py/G), which was through 1,3-dipolar cycloaddition azomethine ylides. Ru(bpy)2(py)Cl/G characterized by atomic force microscopy (AFM), scanning electron (SEM), transmission (TEM), Raman spectra, Fourier transform infrared (FTIR), and...
Abstract Assembling quantum dots (QDs) into van der Waals (vdW)‐layered superstructure holds great promise for the development of high‐energy‐density metal anode. However, designing such a remains to be challenging. Here, chemical‐vapor Oriented Attachment (OA) growth strategy is proposed achieve synthesis vdW‐layered carbon/QDs hybrid superlattice nanosheets (Fe 7 S 8 @CNS) with large vdW gap 3 nm. The Fe @CNS assembled by carbon‐coated @C) QDs as building blocks. Interestingly, exhibits...
The photocatalyst TiO 2 /SiO was prepared and used for chlorine dioxide photocatalytic oxidation of simulated fuchsine wastewater under UV irradiation. removal efficiency treated by process is higher than that chemical process. By using UV-Vis online FTIR analysis technique, the intermediates during degradation were obtained. benzene ring in degraded into quinone carboxylic acid finally changed carbon water oxidation. reaction mechanism irradiation proposed based upon experiment evidence.
Aniline is one of the important organic chemical raw materials and widely used in production industry, including dyes, pharmaceuticals, pesticides, explosives, spices, etc. At present, yield selectivity aniline synthesis by direct amination are relatively low, how to improve catalytic efficiency has become an urgent problem be solved. A series Ti-V-MCM-41 catalysts with different silicon-titanium ratios was prepared hydrothermal method. According analysis XRD, FT-IR, UV-vis DRS, BET, SEM...
Photoelectrocatalytic (PEC) degradation of organic pollutants into CO2 and H2O is a promising strategy for addressing ever-growing environmental problems. Titanium dioxide (TiO2) has been widely studied because of its good performance environmental benignancy; however, the PEC activity TiO2 catalyst is substantially limited due to fast electron–hole recombination. Herein, we report nanocone-based photoelectrocatalyst with superior degradation outstanding durability. The unique conical...
