Abstract
The codoping of TiO2 provides a promising approach to extend the photo-response of TiO2 to the more abundant visible region and emerges as a very active research field in the photocatalytic degradation of organic pollutants very recently. The present review first gives an overview on the general performance of the co-doped TiO2 visible-light photocatalysts and then the current progresses in the synthetic methods and structure characteristics of the codoped TiO2 are summarized and discussed. The synergistic effects of co-doping on the optical absorption, the redox ability, the mobility and surface trapping of the photogenerated carriers are highlighted in the terms of the electronic, crystalline, and surface properties in the codoped TiO2, relative to the monodoped ones.

Carbohydrates conversion in biofuels and bioproducts
Biomass pretreatment, hydrolysis, and saccharification of carbohydrates, and sugars bioconversion in biofuels and bioproducts within a biorefinery framework. Carbohydrates derived from woody biomass, agricultural wastes, algae, sewage sludge, or any other lignocellulosic feedstock are included in this issue. Simulation, techno-economic analysis, and life cycle analysis of a biorefinery process are ...read more
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
