 PAGE \* MERGEFORMAT 17 Some examples of particuology in heterogeneous catalysis Hadi Nur Ibnu Sina Institute for Fundamental Science Studies, Universiti Teknologi Malaysia, 81310 UTM Skudai, Johor, Malaysia e-mail: hadi@kimia.fs.utm.my; website: Abstract The design and synthesis of particulate materials for?new catalyst systems?with novel properties remain a big challenge today.?Here an attempt has been made to synthesize particulate materials for several heterogeneous catalytic systems, which contain examples from our recent research projects in this area. The particulate catalysts have been designed for single centre catalyst, phase-boundary catalyst, bifunctional catalyst, photocatalyst and chiral catalyst. In our current research, the synthesis of well-aligned titanium dioxide catalyst with very high length to the diameter ratio was also demonstrated for the first time by sol-gel method under magnetic field with surfactant as structure aligning agent.

PARTICUOLOGY IN HETEROGENEOUS CATALYSIS The word particuology was coined to parallel the technical terminology for the science and technology of particles by combining the Latin prefix particula for particles and the Greek suffix logia denoting subject of study [1]. Particuology in heterogeneous catalysis is an important topic in both of academic and industry point of view since the heterogeneous catalysis on of the important field in chemical industries. Heterogeneous catalysis one of the keys factor for sustainable development of industrial society. The following are examples of my researches, which were carried out by me together with my colleagues and students. Some of the review on our researches had been published in books and journals [2–4]. This paper also summarizes some of the research that is bei
