Bulk quantities of nitrogen-rich graphitic carbon nitride are synthesized via a facile reactive pyrolysis process with mixture melamine and cyanuric chloride as the molecular precursors. Scanning electron microscopy transmission studies show that micrometer-sized hollow vessels high aspect ratios have been successfully elaborated without designed addition any catalyst or template. The composition prepared determined by combustion method is C(3)N(4.91)H(1.00)O(0.22), N/C ratio to be 1.64,...

Creatively constructing Z-scheme composites is a promising and common strategy for designing effective photocatalyst systems. Herein, we synthesized Fe2O3@Ag-ZnO@C heterostructures from the Fe-MOFs applied it to photodegradation of tetracycline methylene blue pollutants in wastewater. The optimized sample exhibits remarkable performance as well stability under visible light irradiation. calculating experimental results demonstrate that Fe2O3@ZnO nanointerface carbon sheath together boost...

In recent decades, tremendous attention has been paid to the development of new electrode materials with high capacitance meet requirements in supercapacitors. Among vanadium oxides, VO2(A) recently received increasing due its unique layered structure, phase transformation and applications Li-ion batteries. However, few studies have focused on electrochemical properties as capacitors. Herein, we develop a facile hydrothermal method prepare VO2(A)@C core-shell structured composites by...

Hydrogen and other renewable resources derived by sunlight have attracted great attention to sustainable development. But the photochemical performance of diverse systems is restricted because poor efficiency photon absorption, easy recombination photogenerated electron–hole pairs, slow transfer charge carriers. Single-atom catalysts (SACs), in which isolated atoms are supported on supports without forming nanoparticles, received increasing interests photocatalysis due high catalytic...

The stereospecific design of the interface effects can optimize electron/Li-ion migration kinetics for energy-storage materials. In this study, an electric field was introduced to silicon-based materials (C-SiOx@Si/rGO) through rational construction multi-heterostructures. This achieved by manipulating physicochemical properties at atomic level advanced Li-ion batteries (LIBs). experimental and density functional theory calculations showed that unbalanced charge distribution generated a...

Hybrids consisting of mesoporous carbon and uniform sized, regular morphology even distributed metal silicate have been a challenge, although they are potential promising material for electrochemical supercapacitor. In this work, we synthesized hybridized supercapacitor electrode layered nickel Ni3Si2O5(OH)4 nanoparticles on the porous derived from calcined natural bamboo leaves (C-SiO2). The good combination C-SiO2 in situ generated silicate, which turned out to be an outstanding electrode,...
