Cu/Ba/bauxite possesses superior NOx storage and reduction (NSR) performances, high thermal stability, strong resistance against SO₂ poisoning and outstanding regeneration ability in comparison with Pt/Ba/Al₂O₃. It can serve as a cheap and promising alternative for traditional Pt/Ba/Al₂O₃ in NOx removal from lean-burn engines.
The aim of software testing is to find faults in the program under test. Previous methods of path-oriented test data generation can generate test data traversing target paths, but they may not guarantee to find faults in the program. We present a method of evolutionary generation of test data for path coverage with faults detection in this paper. First, we(More)
An electrospinning with calcination process was employed for the synthesis of La1-xCexCoOδ (x=0, 0.2, 0.4, 0.6, 0.8, and 1.0) oxides. These catalysts were investigated in terms of total benzene oxidation, and characterized by means of XRD, BET, H2-TPR, SEM, XPS, and TEM techniques. The results show that the amount of Ce doping obviously affects the(More)
The objective of this work was to develop a novel organic-inorganic hybrid nanomaterial from agricultural biomass waste for environmental applications. The sugarcane bagasse (SB) supported TiO2 hybrids were firstly synthesized via a sol-gel method. A series of characterizations were carried out to reveal the structures and components of obtained hybrids.(More)
A new versatile method was developed for the synthesis of various transition metal oxides with uniform 1D structures via electrospinning combined with heat treatment. The 1D nanowire or hollow tubular structure can be tuned by controlling heating rates. Interestingly, NOx conversion is ca. 99% at 200 °C in hollow tubular CuCo2O4.
