Research points to more effective catalyst materials for petrochemical industry
May 12, 2006Nickel oxide is a very important chemical in modern industrial processes. It is commonly used as a catalyst within the petrochemical industry in areas like the synthesis of olefin gas and the reforming reaction of methane. The performance of the catalyst is closely related to particle properties of synthesised nickel oxide. Particle sizes, shapes and porosities are largely determined by various synthesis techniques but it is suggested that precursor material may also strongly influence these properties.
Catalytic materials are most effective when synthesised as spherical particles and among the numerous methods suggested for synthesizing spherical particles, the sol-gel method is currently the most promising.
The Sol-Gel method was used by Thai researchers Chatchawan Sookman and Paisan Kongkachuiychay from Kasetsart University different nickel precursors and bases yielded NiO particles with differing particle sizes.
In all, six different systems were studied. NiO particles from Ni(NO3)2 were the largest followed by NiO from NiCl2 and NiSO4 respectively. In addition, use of NaOH yielded slightly larger NiO particles compared to when KOH was used as a precursor. Furthermore, the NiO crystal size was found to increase with an increase in the calcination temperature and concentration of nickel salts.
The researchers found Ni(NO3)2 and NaOH were the most appropriate reactants for synthesis of nickel oxide due to the properties of the precursors.

X-rays have been used for decades to take pictures of broken bones, but scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory and their collaborators have developed a lensless X-ray technique that can take images of ultra-small structures buried in nanoparticles and nanomaterials, and features within whole biological cells such as cellular nuclei.
Titan's icy climate mimics Earth's tropics
If space travelers ever visit Saturn's largest moon, they will find a tropical world where temperatures plunge to minus 274 degrees Fahrenheit, methane rains from the sky and dunes of ice or tar cover the planet's most arid regions. These conditions reflect a cold mirror image of Earth's tropical climate.
