visible light photodegradation of phenol on mwnt tio2 composite catalysts prepared by a modified sol gel method
Journal of Molecular Catalysis A-chemical, 2005Co-Authors: Wendong Wang, Philippe Serp, Philippe Kalck, Joaquim L FariaAbstract:Abstract Multi-walled carbon nanotubes (MWNT) and TiO2 composite catalysts were prepared by a modified sol–gel method. The nanoscaled composite materials were extensively characterized by TG, N2 adsorption-desorption isotherm, XRD, SEM, EDX, TEM and UV–vis spectra. The photocatalytic degradation of phenol was performed under visible light irradiation on these catalysts. An optimum of synergetic effect on photocatalytic activity was observed for a weight ratio MWNT/TiO2 equal to 20% with an increase in the first-order rate constant by a factor of 4.1. The synergetic effect, induced by a strong interphase interaction between MWNT and TiO2, was discussed in terms of different roles played by MWNT in the composite catalysts.

synergetic effect of cu and graphene as cocatalyst on tio2 for enhanced photocatalytic hydrogen evolution from solar water splitting
Journal of Materials Chemistry, 2012Co-Authors: Xiaojun Lv, Shixiong Zhou, Wenfu Fu, Haixin Chang, Chen Zhang, Yong ChenAbstract:In photocatalytic solar water splitting systems, non-noble and highly active cocatalysts have always been pursued with tremendous interest. Herein an active and cheap photocatalyst, using Cu and graphene synergetically as co-catalysts immobilized on TiO2, was studied. This synergetic photocatalyst displayed enhanced photocatalytic hydrogen generation from water splitting in the presence of methanol as a sacrificial reagent. The hydrogen generation efficiency from the Cu–graphene synergetic cocatalyst was about 5 times higher than that of a pure graphene cocatalyst, and can be compared with that of systems containing the well-known Pt cocatalyst. Therefore this Cu–graphene synergetic cocatalyst provides an inexpensive means of harnessing solar energy to achieve efficient hydrogen evolution from water splitting.
