Increasing interests have been showed on confinement effects in catalysis1,2,3.Herein,we discussed the concept ofconfinement field into two-dimensional(2D) systems formed by graphene(Gr) covered Pt(11
Vinyl(C2H3)+acetylene(ethyne,C2H2),one of the important building block reactions to form aromatic rings,was studied using laser flash photolysis-laser absorbance spectrometry and time-resolved photoio
