The Ag2O–g-C3N4 composite was prepared by the coprecipitation method and well characterized X-ray diffraction, transmission electron microscopy with energy dispersion spectroscopy, UV-vis diffuse reflectance photoelectron photoluminescence spectroscopy surface photovoltage spectroscopy. photocatalytic activities were evaluated in degradation of Rhodamine B aqueous solution. results showed that Ag2O sized 5–10 nm highly anchored on pure g-C3N4 support, causing to show stronger absorption...
A series of mesoporous graphitic carbon nitride (mg-C3N4) materials have been prepared with urea and tetraethylorthosilicate (TEOS) as the precursors, which were thermally polycondensed to obtain g-C3N4/silica composites, after silica was removed, mg-C3N4 large surface area (170 m2 g–1) successfully prepared. Excitingly, TEOS did not only act a mesoporous-directing agent but also promoter for polycondensation g-C3N4, made proceed at relatively low temperature. Thus, volatilization or/and...
Due to the loaded OMC, photogenerated electrons and holes were efficiently separated, which made OMC/g-C<sub>3</sub>N<sub>4</sub> exhibit enhanced visible light activity.
Catalytic coupling of carbon dioxide with epoxides to obtain cyclic carbonates is an important reaction that has been receiving renewed interest. In this contribution, the cycloaddition in presence various hydrogen bond donors (HBDs) catalyzed by hydroxyl/carboxyl task-specific ionic liquids (ILs) studied detail. It was found activity ILs could be significantly enhanced ethylene glycol (EG), and EG/HEBimBr were most efficient catalysts for CO2 propylene oxide. Moreover, binary also...
g-C<sub>3</sub>N<sub>4</sub> prepared from guanidine hydrochloride exhibited a large surface area and reduced recombination rate of electrons holes, leading to improved photocatalytic activity for degrading RhB under visible light.
A periodic mesoporous organosilica with a basic urea-derived framework (PMO-UDF) was prepared and characterized thoroughly. The PMO-UDF showed an enhanced CO2 capture capacity at low pressure (≤1 atm) exceptional catalytic activity in coupling reactions various epoxides to yield the corresponding cyclic carbonates under mild conditions because of presence high surface area, pyridine units, multiple hydrogen-bond donors. highly stable catalyst could be reused least six successive times...
Visible-light-responsive mesoporous carbon/C-doped ZnO (mC/C-ZnO) composites were fabricated using a facile, fast, one-step process in CO2-expanded ethanol solution. It is green and sustainable that does not need tedious pretreatment, surfactants or precipitants. CO2 played triple roles the synthesis of mC/C-ZnO composites; first was to provide simple physical expansion evenly dope carbon ZnO; second offer some chemical groups such as CO3(2-) HCO3(-), facilitating uniform complete deposition...
Smaller Ag<sub>2</sub>CrO<sub>4</sub> nanoparticles were highly dispersed on the large surface area g-C<sub>3</sub>N<sub>4</sub> sheets and exhibited significantly enhanced photocatalytic activity.
Novel Zn-TSILs catalysts were developed, which showed high activity towards the cycloaddition of CO<sub>2</sub> to epoxides due synergetic effects.
Nitrogen defect-modified mesoporous g-C<sub>3</sub>N<sub>4</sub> exhibits excellent photocatalytic ability for water splitting H<sub>2</sub> evolution.
A series of visible-light-induced 2D/2D layered g-C3N4/Bi12O17Cl2 composite photocatalysts were successfully synthesized by a one step chemical precipitation method with g-C3N4, BiCl3 and NaOH as the precursors at room temperature characterized through XRD, FTIR, XPS, TEM, BET UV-vis DRS measurements. The results FTIR XPS indicated that g-C3N4 has been introduced in Bi12O17Cl2 system. TEM image demonstrated there was strong surface-to-surface contact between 2D layers nanosheets, which...
