Abstract
With the decreasing fossil resources and worsening of environment,utilization of solar energy and transforming harmful substance into useful resource are both good solutions,meanwhile,the catalysts play an important role in the above-mentioned and utilization of the catalyst has attracted many countries’ the last decade,the rapid development of two-dimensional materials(2D) creates an opportunity for obtaining catalysts with high ponents greatly improve catalytic activities of the hybrid nanocatalysts owning to their unique far,the insufficient studies on synthetic techniques,structure designs and catalytic mechanism researches have greatly limited application and development of 2D present thesis attempts to obtain high·activity hybrid catalysts
based on 2D substances with simple and high-efficiency construction
works are presented as follows:
Firstly,the CdS/RGO posite was essfully synthesized by a reflux condensation method in Ⅳ匝Was used as both solvent
and reducing effect of RGO content in CdS/RGO posites on the photocatalytic degradation of Rhodamine B(RhB)was was replaced with GO in posite SO as to investigate what a role conductivity played in photocatalytic selectivity of the catalyst was studied by
changing the substrate the end,the mechanism of the improvement of
photocatalytic activity of CdS anchored on RGO under solar irradiation was suggested and results showed that the optimum content of RGO to CdS was 5%while the photocatalytic activity of CdS/RGO posite was about 300%times higher than that of pure of RGO in posite played an important role in photocatalytic higher photocatalytic
degradation rate was achieved for pared to MB and mechanism of the improved photocatalytic activity of CdS/RGO posite could be attributed
