【摘要】The pH value of the influent was adjusted by sulfuric acid (H2SO4) or sodium hydroxide (NaOH) to investigate the effect of pH value on the activity of the catalyst.The results showed that the pH value of the influent was in the range of 5.5～7.5,and the activity of the cataly...
In this work an electrochromic polyaniline (PANI) thin film and a viscous electrolyte, formed by mixing a basic aqueous solution of polyethylenimine (PEI) and concentrated sulfuric acid (H2SO4), have been used as the main components of an ECD. The pH value of the electrolyte is a function ...

Compared to other techniques, chemical reduction of GOs is attractive because of its reliability, amenability to large scale production and exceptionally low cost. In this regard, exfoliation of graphite by oxidation using strong acids such as H2SO4 and KMnO4 is one efficient way to produce single...
