In this study, a bimetallic oxide catalyst of cobalt-manganese (CoMn2O4) was synthesized using the sol-gel method, and it then characterized variety techniques such as scanning electron microscopy (SEM), transmission (TEM), X-ray diffraction (XRD) spectroscopy, photoelectron spectroscopy (XPS), nitrogen adsorption-desorption isotherms. The obtained novel catalyst, i.e., CoMn2O4, used an activator peroxymonosulfate (PMS) for catalytic degradation commonly-used UV filter,...
In this paper, using rice straw as a raw material and urea nitrogen precursor, composite catalyst (a nitrogen-doped biochar at the pyrolysis temperature of 800 °C, recorded NRSBC800) was synthesized by one-step pyrolysis. NRSBC800 then characterized XPS, BET, TEM other technologies, its catalytic performance an activator for permonosulfate (PMS) to degrade acid orange 7 (AO7) studied. The results show that introduction N-doping significantly improved NRSBC800. NRSBC800/PMS oxidation system...
Toluene side-chain alkylation with methanol for the styrene monomer formation remains a great challenge. An optimal synergy between acidic and basic sites on zeolites is required an efficient catalysis process. It important to modulate surface Lewis acid–base pairs precisely. Herein, we report strategy restructure in cesium-modified X zeolite (CsX) by N doping. In process of toluene alkylation, CsX-BN-600 catalyst, where species doped into framework zeolite, exhibits 2.7 times rate much...
In this paper, the ultraviolet/persulfate (UV/PDS) combined oxidation process was used to remove ethyl 4-aminobenzoate (Et-PABA), one of typical 4-aminobenzoic acid (PABA)-type UV filters. The effects various factors on removal Et-PABA using UV/PDS were investigated, and degradation mechanisms explored. results showed that can effectively 98.7% within 30 min under conditions: intensity 0.92 mW·cm−2, an initial concentration 0.05 mM, a PDS 2 mM. rate increased with increase in dosage...
A series of rice husk biochar (RHBC) modified bimetallic oxides were prepared using a simple pyrolysis method to activate peroxymonosulfate (PMS) for the degradation acid orange G (OG). The results demonstrated that 50 mg L-1 OG was completely decomposed by 1 mM PMS activated with 100 RHBC-CuCo2O4 within 15 min at initial pH 3.4. rate constant k RHBC-CuCo2O4/PMS (0.95 × 10-1 min-1) five times greater than CuCo2O4/PMS (0.19 min-1), suggesting introduction RHBC significantly improved activity...
The carbon nanotubes (CNT) were modified with graphitic nitride (g-C3N4) for the first time to prepare new metal-free composites peroxymonosulfate activation. results showed that modification of CNT g-C3N4 significantly enhanced catalytic performance in activating PMS degradation p-hydroxybenzoic acid (HBA)than traditional N doping. Moreover, oxidation system was not affected by water quality factors (e.g., Cl−, NO3−, HCO3−, and humic acid) as it had a high pollutant mineralization rate...
Layered double hydroxide (LDH) as an adjustable layered materials were considered good candidates for the supports of water-gas Shift (WGS) catalysts. However, there is rare report about exfoliation preparation and WGS application LDH-based catalysts containing BO33- intercalated anions. Herein, we reported a mild alkali treatment modulation borate anions in LDH improving catalytic performance Au-based Compared with inactive catalyst without treatment, moderate consumes anions, awakening...
ZSM-5 zeolites with accessible micropore architecture and tunable acid-base sites are important shape-selective catalysts. However, the presence of exposed straight channels external conventional has a negative impact on shape selectivity. Herein, we report direct synthesis an intergrowth zeolite mimicking mortise-tenon joints. It can be revealed by various methods that shows inverse Al gradient from surface to core zeolite. More importantly, sinusoidal predominantly opened their surfaces...
This work demonstrates the potential utility of ferrate(VI)-based advanced oxidation processes for degradation a representative UV filter, BP-4. The operational parameters oxidant dose and temperature were determined with kinetic experiments. In addition, effects water constituents including anions (Cl−, HCO3−, NO3−, SO42−), cations (Na+, K+, Ca2+, Mg2+, Cu2+, Fe3+), humic acid (HA) investigated. Results suggested that removal rate BP-4 (5 mg/L) could reach 95% in 60 min, when...
