Abstract
It is now extensively established that the ideal way to achieve the development in heterogeneous catalysis is to utilize semiconducting titanium dioxide (TiO2) based particles with high surface area as well as mesoporous structure. This can efficiently accommodate substrates on its surface to interact with each other. Most of the reduction-oxidation type organic transformations, degradation of hazardous organic moieties are feasible at moderate reaction conditions with the help of TiO2 nanoparticles due to their ability to form composites with enhanced performance, better metal support interactions, chemical stability, selectivity and presence of reactive acid-base sites on its surface. This review article provides a balanced and comprehensive analysis of some innovative and ambitious strategies for modification of TiO2 host material for heterogeneous catalysis: a) making its composites with other materials; and b) doping by metal or non-metal.
Keywords: Titanium dioxide, heterogeneous catalysis, mixed oxide composites, metal support, organic transformation.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
