β-Bi2O3 particles were synthesized by a polyacrylamide sol-gel method. The sonocatalytic activity of was evaluated degrading Rhodamine B (RhB) under the ultrasonic irradiation, revealing that exhibit good activity. effects various experimental factors including frequency (f), solution temperature (T), catalyst dosage (Ccatalyst) and initial RhB concentration (CRhB) on sonocatalysis efficiency investigated. optimum conditions for degradation are obtained to be f=60 kHz, T=40 °C, Ccatalyst=3 g...
Graphitic phase carbon nitride (g-C3N4) demonstrates tremendous potential for photocatalytic degradation of organic pollutants, but its performance is severely limited by the high recombination photogenerated electron–hole pairs. This study introduces an innovative approach oxalic acid-assisted thermal polycondensation to construct a series oxygen-doped porous g-C3N4 (OCN) nanostructured materials, which simultaneously utilizes heat-induced foaming mechanism acid achieve element doping...
Cobalt diselenide @ carbon nanotube (CoSe 2 @CNTs) composites featuring a heterogeneous structure were synthesized using solvothermal method.
An ultra-facile fabrication process for the preparation of phosphorus doped porous carbon nanofibers (P-PCNFs) through electrospinning and heat treatment method has been studied. The materials were characterized by X-ray diffraction, scanning electron microscopy, photoelectron spectroscopy. Studies showed that fabricated P-PCNFs have unique fibers structures, large specific surface area (462.83 cm2 g-1), abundant microporous mesoporous structures. spectroscopy analyses revealed contents...
Carbendazim (CBZ), as a highly effective benzimidazole fungicide, has good control effect on various crops caused by fungi. However, excessive use of CBZ in water, atmosphere, soil, and serious effects. The efficient degradation is an way to reduce its toxic effect. In this work, the type S-scheme Ag/AgBr/BiOBr heterojunction photocatalyst was effectively prepared simple one-step solvothermal situ method first applied mineralization CBZ. effects molar ratio AgBr BiOBr, catalyst dosage,...
In this work, the activated carbon nanofibers were prepared by hydrolysis of mat using bio-enzymatic method. The nanofiber was hydrolyzed medium temperature α-amylase, and carbonized to obtain nanofibers. results indicated that CNFs had good fiber structure, small electrolyte diffusion resistance, rich pore as well large specific surface area (268.09 m2/g). Furthermore, effects enzymatic temperature, enzyme dosage time on mass loss rate investigated. achieved best electrochemical performance...
Antibiotic residues have been found in several aquatic ecosystems as a result of the widespread use antibiotics recent years, which poses major risk to both human health and environment. At present, photocatalytic degradation is most effective environmentally friendly method. Titanium silicon molecular sieve (TS-1) has widely used an industrial catalyst, but its application wastewater treatment limited due small pores few active sites. In this paper, we report method for preparing multistage...
Abstract Bismuth Oxyhalide (BiOX, X=Cl, Br, I) has been widely used in water purification, environmental remediation and other fields due to its special layered structure good photocatalytic performance. In this work, BiOCl, BiOBr BiOI photocatalysts were successfully synthesized by a simple solvothermal method first applied the mineralization degradation of carbendazim (CBZ). The performance BiOX CBZ was studied under different light sources pH conditions. And influence mechanism three...
A novel free radical reaction combined with high-performance LC–photodiode array–ESI–MS/MS screening method was developed for the detection and identification of natural antioxidants from whole Scutellariae. Six compounds Scutellariae extracts were found to possess a potential antioxidant capacity, their radical-scavenging activities investigated in detail. The six identified as baicalin, baicalein, scutellarin, scutellarein, wogonoside chrystin-7-glucoronide. present study reveals that...
Carbon nanofibers (CNFs) have been widely used in electrochemical energy storage devices because of their excellent conductivity, extremely large surface area and structural stability. Herein, we obtained a viscous, liquefied bio-stalk carbon via the simple chemical treatment biomass, mixed it with polyacrylonitrile to prepare spinning solution. Subsequent electrospinning high temperature activation resulted successful preparation lignin-based activated nanofibers. The as-prepared exhibited...
