Combination of Carbon Nitride and Semiconductors for the Enhancement of the Photocatalytic Degradation of Organic Pollutants and Hydrogen Production

Abstract

This chapter summarizes the utilization of promoted graphitic carbon nitride (gCN) semiconductors in photocatalytic hydrogen generation and photocatalytic environmental remediation. This includes the methods of tailoring, fine-tuning and promoting the properties of gCN, such as band gap and catalytic activity related features, with particular focus on the enhancement of photocatalytic degradation of organic pollutants, dyes, and hydrogen production, which are discussed and summarized to date. Preparations of such combinations include pre, in situ and post incorporation of semiconductors of various forms or functionalization or mechano-composites. This chapter also delves into the characterization of such combinations when necessary. The present barriers in the fabrication of gCNs and their photocatalytic applications in environmental, hydrogen production, and pollutants' degradation are discussed along with their future outlook.
