A simple approach to produce 34 mM hydrogen peroxide utilizing carbon nitride photocatalysts
The production of hydrogen peroxide (H2O2) by photocatalytic reduction of oxygen (O2) has attracted considerable attention as a more efficient and cleaner method than traditional methods for synthesizing H2O2. Carbon nitride (C3N4) is a suitable photocatalyst for H2O2 production under solar light due to its band gap. The objective of this study was to achieve rapid production and high concentration of H2O2 over a C3N4 photocatalyst through the strategy of increasing the H2O2 production rate and decreasing the H2O2 decomposition rate. The results showed that 34 mM H2O2 was produced by photocatalytic reactions in an alcohol at slightly elevated temperatures under visible light irradiation. To gain a deeper understanding of the rapid production and high concentration of H2O2, various parameters were investigated.
