“…The PSL particles were used as a pore template. The spherical PSL particles, 200 nm in diameter, were synthesized from a styrene monomer according to the method in previous reports [21,22]. CeO 2 nanoparticles less than 10 nm in diameter were synthesized from cerium nitrate hexahydrate (Ce(NO 3 ) 3 Á6H 2 O, Sigma Aldrich, 99%) by means of flame spray pyrolysis (Fig.…”

“…The aerosol process is a very rapid process when used to prepare porous composite particles from the sprayed droplets of a colloidal mixture [22]. This method has been widely used due to its many advantages, including the fact that it is a simple system that is also cost effectiveness, and the fact that it can be scaled up to quantities in the tons [23][24][25].…”

In this study, nickel oxide was prepared through the calcination of extrusion dripped chitosan/nickel nitrate beads. The morphology and structural properties of the products were studied using various characterization techniques. Uniformly distributed nickel oxide was formed as observed from the studies of surface morphology where the processing parameters play a huge role on the resulting morphology. TEM results have shown that nickel oxide with crystallite sizes of 10–30 nm was obtained. The Fourier-transform infrared spectra studies show an intense peak at 525 cm−1, which is attributed to the vibration of Ni–O bond. Furthermore, the XRD results show NiO diffraction peaks correspond to (111), (200), (220), (311), and (222) which indicates that a bunsenite structure with a face-centered cubic phase was produced in this study. The usage of 500°C as the lower limit in this study is justified due to the complete removal of the templating material as seen in the thermalgravimetric analysis studies. Furthermore, it was obtained that the largest surface area of nickel oxide synthesized using this technique is 48.024 m2/g with pore sizes of 19.843 nm. The usage of chitosan as a green template for the synthesis of nanoparticles has shown promising results which allows a more economical and sustainable approach for the fabrication of nanomaterials

“…In this paper, we report the development of reusable water filter using titania as the source material. Many authors have reported the use of titania as filter or photocatalyst materials either in dense or porous structures [5][6][7][8][9][10]. To the best of our knowledge, there is no report on the preparation of porous tinania for use as filter using a simple pressing and simple heating method using titania powder as precursor.…”

Abstract. We report the fabrication of microporous filter for use in filtering both inorganic and organic substances from liquid materials. Titania (TiO 2 ) anatase was used as the main material for this filter. Polyethylene glycol (PEG) with average molecular weight of 20,000 was also used as additive to control the formation of pores, especially pore sizes. The mixture of titania and PEG was pressed into cylindrical tablet shape at room temperature and then simply heated inside a furnace up to temperature where the PEG decomposed into gas to leave only connected titania particles. The use of titania as base material for the filter allows the organic substances that trapped inside the filter pores to be easily removed by heating up the used filter at above decomposition temperature of the trapped organics. We also made other filter by adding small amount of silica (SiO 2 ) particles to reduce the size of the pores as well as to improve the mechanical strength. We observed that filters containing silica particles, with smaller in size compared to titania, resulted in better mechanical strength, smaller in pore sizes and better filtering results in term of turbidity and dissolved oxygen (DO) content. This method is potential for development of larger scale and cheaper water filters for use in various applications.
