Properties microwave exposure effects

The effect of microwave irradiation on the catalytic properties of a silver catalyst (Ag/Al203) in ethane epoxidation was studied by Klimov et al. [91]. It was found that on catalyst previously reduced with hydrogen the rates of both epoxidation and carbon dioxide formation increased considerably on exposure to a microwave field. This effect gradually decreased or even disappeared as the catalyst attained the steady state. It was suggested that this was very likely because of modification of electronic properties of the catalyst exposed to microwave irradiation. 

Metal-free nitrogen and phosphorus dual-doped, electrocatalytically active, functionalized nanocarbon (FNC) and photoluminescent carbon nanodots (PCNDs) were simnltaneonsly synthesized using a facile one pot microwave-assisted process (Prasad et al., 2013). In addition to the electrocatalytic activity, FNC also shows attractive properties as a metal-free oxygen reduction catalyst and it is resistant to methanol crossover effects in alkaline media The 5-10 nm PCNDs, exhibiting blue fluorescence nnder UV exposure were successfiilly used for bioimagrug apphca-tions.
