Abstract

The influence of the potassium metal cation on the graphitic carbon nitride (g-CN) photocatalyst has been studied in the partial oxidation of 5-hydroxymethyl-2-furfural (HMF) to 2,5-furandicarboxaldehyde (FDC).

The aim of this study was to understand if the presence of K in CN could increase the oxidative conversion of HMF to high added value species.

Two sets of photocatalysts were prepared by following two different methodologies. In both series of the materials, the precursor of CN was melamine with different types of the K containing species including KCl and KOH in one case and KNO alone in the other case. However, for both series of photocatalysts, materials were prepared with different amounts of potassium.

The results obtained by using materials prepared by the two different methodologies indicate that in both cases the presence of K was almost irrelevant at least for the lower amounts of potassium content. On the contrary, its presence was beneficial for the activity the photocatalytic partial oxidation reaction of the alcohol for the highest K content.

Some of the prepared K containing g-CN materials showed increased photocatalytic activity for the partial oxidation reaction of HMF in water, particularly by using natural solar light as the irradiation source.
