Abstract NO x abatement has been an indispensable part of environmental catalysis for decades. Selective catalytic reduction with ammonia using V 2 O 5 /TiO is important technology removing emitted from industrial facilities. However, it a huge challenge the catalyst to operate at low temperatures, because ammonium bisulfate (ABS) forms and causes deactivation by blocking pores catalyst. Here, we report that physically mixed H-Y zeolite effectively protects vanadium active sites trapping ABS...
ZnS particles are synthesized by adding ethylenediamine (en) and its derivatives, triethylenetetramine (trien) ethylenediaminetetraacetate (EDTA), as capping agents. In the capped particles, Zn S defects due to O, N-doping loading of carbon dots (CDs) confirmed. The degree is suggested from photoluminescence (PL) spectra density states calculations. intensities PL lowered in order ZnS-none> ZnS-EDTA> ZnS-en> ZnS-trien, while photocurrent densities increased opposite order. Time resolved...
Today, the overall occurrence of re-emerging and rising illnesses has been a serious load on economies as well public health. Here, we describe simple, nontoxic eco-friendly method for synthesis milk protein (MP)-stabilized silver nanoparticles (MP-s-AgNPs) using ultrahigh-temperature full cream milk. Highly stable AgNPs were prepared with fair control over their size, without any reducing or stabilizing agent, formation was attributed to presence MP casein. Ag+ ion reduction possibly caused...
Herein, we show that the weak interaction of CO with Pt/TiO2 under oxidation condition is origin higher activity Pt/rutile than Pt/anatase. The results temperature-programmed desorption (TPD) and in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) indicate onset temperatures on freshly prepared Pt/anatase are same. However, CO-TPD curves after reaction test temperature shifts to a lower temperature, while for does not change. pulse using DRIFTS reveals reacted oxygen...
This study presents the synthesis and characterization of non-isocyanate polyurethanes (NIPU) derived from copolymerization cyclic-carbonated soybean oil (CSBO) cyclic carbonate (CC)-terminated poly(ether carbonate) (RCC). Using a double-metal cyanide catalyst, polyol was first synthesized through carbon dioxide propylene oxide. The terminal hydroxyl group then subjected to substitution reaction with five-membered CC using glycerol-1,2-carbonate oxalyl chloride, yielding RCC. Attempts...
In this study, hydrogen was recovered and purified by using a membrane contactor unit from CO2-rich gas without the use of any basic chemicals such as amines. The operational parameters were adjusted to achieve high CO2 removal H2 recovery. effects flow rate, pressure, composition (CO2/H2 ratio), pressure difference between liquid gas, gas/liquid ratio on recovery investigated. Depending contact time could be controlled, changing absorption amounts H2. Regarding composition, an increase in...
We have developed a facile and sustainable method to produce novel θ-Al2O3-supported CuCl adsorbent through impregnation methods using CuCl2 as the precursor. In an easy two-step process, θ-Al2O3 was impregnated with known concentration of solutions, precursor calcined prepare oversupport. The compared prepared conventional salt. adsorbents were characterized via X-ray diffraction (XRD), thermal gravimetric analysis (TGA) temperature-programmed reduction (H2-TPR). Overall, indicates high CO...
Pet has been serving as an emotional companion to people. However, nowadays it is common that people are too busy take care of their pet due everyday work. This research see the possibility robot can replace role taking pets on behalf owner and conventional human-robot interaction (HRI) be extended robots animals. In this paper, concept animal-robot (ARI) its characteristics presented along with basic experiments. The experiments carried out a cat mobile robots. It clearly shows implementation ARI.
The photocatalytic production of hydrogen from water using solar energy is potentially a clean and renewable source for fuel. This study examines the over In, P-TiO 2 s photocatalysts. 1 mol% In-TiO were produced solvothermal method treated at 500 800 ∘ C to obtain anatase rutile structure, respectively. photocatalysts characterized by X-ray diffraction, photoluminescence spectra, spectroscopy, UV-visible scanning electron microscopy. H methanol photodecomposition was greater structure than...
A single-particle mass spectrometer (SPMS) with laser ionization was constructed to determine the chemical composition of single particles in real time. The technique evaluated using various polystyrene latex different sizes (125 nm, 300 700 and 1000 nm); NaCl, KCl, MgCO3, CaCO3, Al2O3 compositions; an internal mixture NaCl KCl; MgCl2 mixing states. results show that SPMS can be useful for determination characteristics states then applied obtain signatures combustion aerosols (diesel engine...
Low-priced hydrogen is required in petrochemical industry for producing low-sulfur oil, and upgrading low-grade crude oil since environmental regulations have been reinforced. Steel can produce from by-product gases such as Blast Furnace Gas (BFG), Coke Oven (COG), Linze Donawitz (LDG) with water gas shift (WGS) reaction by catalysis. In this study, we optimized conditions WGS commercial catalysts BFG LDG. particular, the influence on activity of gas-hourly-space-velocity,...
