In this article, cesium ions were introduced into the FeCo Prussian blue analogues (PBA) catalyst to increase the styrene conversion and the selectivity in styrene oxide in the reaction of epoxidation of styrene. The conversion of styrene over CsFeCoPBA-1 on the optimal condition reach up to 96%...

Prussian blue and its analogues that have three-dimensional open frameworks are promising cathode materials for sodium-ion batteries owing to their high theoretical capacity and low production cost. Unfortunately, these materials are electrically insulating, which results in adverse effects on t...

We report here the fabrication of MnOx nanoparticles and porous carbon composite via a solution synthesis route followed by carbonization. Poly (acrylic acid) stabilized ultra-small MnO2 nanoparticles (around 1.0 nm) are first produced and then in situ incorporated into the RF resin matrix. The ...

Synthetic dyes having high photostability on hydrophobic fibers such as poly(ethylene terephthalate) (PET) are of interest for use on textile substrates for outdoor applications. While much is known about photostable dyes developed for PET in the 1980s, owing to their viability for use in automo...

The aim of this work was to evaluate the effect of the addition of huitlacoche paste to nixtamalized blue-corn flours (NBCF) on the physicochemical, thermal, and rheological properties of masas. Raw blue maize was nixtamalized (hydrothermal alkalinized process), then was wet-milled in a stone mi...

The present study has been undertaken to evaluate the adsorption in batch mode of a disperse dye (Disperse Blue SBL) by poorly crystalline hydroxyapatite synthesized by coprecipitation between Ca(NO3)2 and (NH4)2HPO4 reagents in aqueous solution at room temperature. The adsorption experiments we...

In this study, low-cost and high adsorption capacity hydrogels based on gum tragacanth biopolymer (GT or TG) and TiO2 nanoparticles were produced by using glutaraldehyde as the crosslinking agent. These hydrogels were applied in photocatalytic process to remove methylene blue from simulated colo...

This paper reports an efficient and convenient removal of disperse blue 2BLN from aqueous solution by the combination of ultrasound and exfoliated graphite. The various affecting factors were studied. The removal ratio of disperse blue 2BLN is 96.9% for the initial concentration of 200 mg/L usin...

The aim of present study is to clean the dye contaminated wastewater in an efficient and environmentally affordable manner using coal fly ash, a waste by-product of thermal power plant. Initially, the low densities, inert and hollow cenospheres were segregated from coal fly ash which are blended...

Catalysts based on the combination of zinc oxide and copper oxide were synthesized at a 80:20 mass ratio by the Pechini method and calcined at 500, 600 and 700 °C for 1 h. These catalysts were characterized by XRD, SEM, FT-IR, BET, UV-Vis, TGA and XRF. They were subsequently tested for the remo...

The green approach based nanoparticles synthesizing is considered as an eco-friendly and cost effective method for producing nanoparticles compared to the other procedures. Additionally, using nanoparticles for the environmental pollution is the big achievement for solving these issues. In this ...

Response surface methodology based on Box-Behnken design (BBD) was successfully applied for the optimization of the UV-LED/FeTiO3 activated persulfate (PS) process. Disperse Blue 3 (DB3) azo dye oxidation was carried out in a quartz jacketed stirred batch reactor using 405 nm UV at 10 W/m−2 as r...

In this study, we applied Kalopanax septemlobus-ZnO nanoparticles (Ks-ZnO NPs) with green approach one-pot synthesis. Further, the extracts were used as capping agent and Zn (OAc)2 as the metal precursor to synthesize ZnO nanoparticles. The formation of ZnO NPs, the surface plasmon resonance wer...

Ethanol was used as a cosolvent to enhance the solubility of disperse dyestuffs in supercritical fluids. In the presence of ethanol, from (1 to 5) mol%, the gas–solid equilibrium data of the Disperse Red 82 and modified Disperse Yellow 119 in supercritical carbon dioxide or nitrous oxide have b...

Semiconductor metal oxides (TiO2, ZnO or SnO2) deposited on a highly ordered mesoporous silica material (called SBA-15 in the literature) were compared for the first time as photocatalysts in the elimination of cationic methylene blue (MB) dye from neutral aqueous solutions by adsorption and/or ...

The aim of this work was to evaluate the catalytic activity of new Au-Fenton-like catalyst in degradation of methylene blue at ambient conditions. For this purpose gold nanoparticles were deposited on commercial ZnO and the material prepared in this way was characterized with N2-adsorption and d...

SummaryDespite heavy research, blue perovskite nanocrystal LEDs have struggled to match the high efficiencies of their red and green cousins, particularly at wavelengths blue enough to meet the NTSC blue standard. One of the most critical problems is the low photoluminescence yield of the nanocr...

Integrated photocatalytic composite adsorbents (IPCA) are used to degrade toxic organic and inorganic compounds in presence of UV/visible light irradiation. The compound preserves all the existing features of individual components and at the same time overcome drawbacks like rapid recombination ...

Shangchuan Island lies in the southern part of the Guangdong Province in China. Historically it is considered as an important berthing wharf of the South China Sea for the Maritime Silk Roads, witnessing the early Sino-Portuguese trades. Related research on the cultural relics in the region has ...
