Experimental information on the O 1s spectra of GO by X-ray photoelectron spectrometry is limited and this will prove to be a liability when analyzing samples that have high carbon to oxygen ratios. Here, the binding energy (B.E.) information of electrons from the O 1s orbital of oxygen atoms in dif...
