Development of visible light sensitive titania photocatalysts by combined nitrogen and silver doping

El Saliby Ibrahim; Erdei Laszlo; Shon Ho Kyong; Kim Jong-Ho (Elsevier, 2011)

In this study we present the effects of non-metal (nitrogen) and metal/non-metal (silver/nitrogen) dopants on titanium dioxide (TiO2) in synthesising visible-light reactive photocatalysts. Nanopowders of TiO2-N and TiO2-Nâ¿¿Ag ...
Effect of shear force, solution pH and breakage period on characteristics of flocs formed by Titanium tetrachloride (TiCl4) and Polyaluminum chloride (PACl) with surface water treatment

Zhao Y.X.; Gao Baoyu; Shon Hokyong; Kim Jong-Ho; Yue Q.Y. (ELSEVIER SCIENCE, 2011)

The growth, breakage and regrowth nature of flocs formed by Titanium tetrachloride (TiCl4) and polyaluminum chloride (PACl) was comparatively evaluated with surface water treatment. A series of jar experiments were conducted ...
Minimization of excess sludge and cryptic growth of microorganisms by alkaline treatment of activated sludge

Na Suk-Hyun; Shon Ho Kyong; Kim Jong-Ho (Springer New York LLC, 2011)

Sludge solubilization was induced by the alkaline-thermal treatment to investigate the cryptic growth and reduction of a large amount of activated sludge produced from wastewater treatment. Activated sludge was divided ...
Preparation and characterisation of mesoporous photoactive Na-titanate microspheres

El Saliby Ibrahim; Erdei Laszlo; Shon Hokyong; Kim Jong; Kim Jong-Ho (Elsevier BV, 2011)

Mesoporous Na-titanate microspheres were fabricated by a simple low temperature hydrothermal synthesis. Microsphereswereobtained after treating TiO2 (Degussa P-25) with a mixture of sodium hydroxide (NaOH) and hydrogen ...
Preparation and Characterisation of TiO2 Nanoparticle and Titanate Nanotube Obtained from Ti-Salt Flocculated Sludge with Drinking Water and Seawater

Kim Jong-Ho; Okour Yousef Hussein; Yang H. S.; Kim J; Shon Hokyong (American Scientific Publishers, 2011)

This study aimed to prepare and characterise titanium dioxide (TiO2) nanopartictes and lilanate nanolubes produced from Ti-sat flocculated sludge with drinking water (DW) and seawater (SW). The Ti-salt flocculated sludge ...
Preparation and characterization of titania nanoparticle produced from Ti-flocculated sludge with paper mill wastewater

Na Suk-Hyun; Shon Ho Kyong; Kim Jong; Park H; Kim Jong-Ho (Elsevier, 2011)

Sludge disposal after flocculation with paper mill wastewater is one of the most costly and environmentally problematic challenges. In this study, an effective sludge recycling process was proposed using Ti-salt coagulant ...
Preparation of Ti02 Nanoparticle from Ti-Salt Flocculated Sludge with Dye Wastewater

Kim Jong; Park H; Shon Ho Kyong; Cho Dong; Kim Geon-Joong; Choi S W; Kim Jong-Ho (American Sciencetific Publishers, 2010)

Dye wastewater flocculation using TiCl4 and FeSO4 coagulants was studied for organic removal and precipitation efficiency. Moreover, TiCl4 was assessed in a pilot-scale flocculation process to investigate organic removal ...
Preparation of Titanium Dioxide Nanoparticles from Electrocoagulated Sludge using Sacrificial Titanium Electrodes

Shon Ho Kyong; Phuntsho Sherub; Vigneswaran Saravanamuth; Kandasamy Jaya; Nghiem L; Kim Gj; Kim J; Kim Jong-Ho (American Chemical Society, 2010)

A comprehensive investigation of electrocoagulation using sacrificial titanium (Ti) electrodes in wastewater was carried out. The effects of specific process variables, such as initial pH, mixing, current density, initial ...
Preparation of titanium dioxide (TiO2) from sludge produced by titanium tetrachloride (TiCl4) flocculation of wastewater

Shon Ho Kyong; Vigneswaran Saravanamuth; Kim In; Cho Jaeweon; Kim Gj; Kim Jason; Kim Jong-Ho (American Society of Civil Engineers, 2001)
Synthesis, characterisation and separation of photoreactive Hydrogen-titanate nanofibrous channel

El Saliby Ibrahim; Shon Hokyong; Kandasamy Jaya; Kim Jong-Ho (Elsevier Inc, 2011)

Australia is the world's largest wool producing country, accounting for about 25â¿¿30% of world production. As a biotemplate, we explored the possibility of using wool to produce micro-channel of Hydrogentitanate nanofibres ...
TiO2 nanoparticles and nanofibres from TiCl4 flocculated sludge: Characterisation and photocatalytic activity

El Saliby Ibrahim; Okour Yousef Hussein; Shon Hokyong; Kandasamy Jaya; Lee Woong; Kim Jong-Ho (Elsevier BV, 2012)

In this study, dye and secondary effluent wastewaters were used to generate a non-hazardous sludge. Anatase TiO2 nanoparticles have been successfully synthesised from the calcination of the TiCl4 flocculated sludge. A ...
Titania Nanomaterials Produced from Ti-Salt Flocculated Sludge in Water Treatment

Kim Jong-Ho; Cho Dong; Kim Geon-Joong; Gao Baoyu; Shon Hokyong (Springer New York LLC, 2011)

Titania is the most widely used metal oxide for the applications of pigments, paper, solar cells and environmental purification. In order to meet the demand of a large amount of titania, our group has developed a novel ...
