This work focuses on synthesizing and characterizing Ti3C2 MXene heterojunctions for enhanced photocatalytic properties in hydrogen photoproduction. The study aims to produce a hybrid material that combines MXenes with other semiconductors to enhance their photocatalytic properties. The selection of semiconductors used in the study was based on environmental sustainability and economic viability to ensure practical applications. While the MXene was produced by an etching reaction of a mother phase (MAX). It was tried to use 3 different agents: HF 5%, LiF, and NH4F2. Only the sample synthesized by HF 5% was used for the heterojunctions, since it was the purest product obtained among the three different reactions. The characterization techniques for the analysis of the MXene and the heterojunctions were XRD, Uv-Vis, SEM, and mass spectroscopy for the analysis of the photocatalytic performances.

Abstract
This work focuses on synthesizing and characterizing Ti3C2 MXene heterojunctions for enhanced photocatalytic properties in hydrogen photoproduction. The study aims to produce a hybrid material that combines MXenes with other semiconductors to enhance their photocatalytic properties. The selection of semiconductors used in the study was based on environmental sustainability and economic viability to ensure practical applications. While the MXene was produced by an etching reaction of a mother phase (MAX). It was tried to use 3 different agents: HF 5%, LiF, and NH4F2. Only the sample synthesized by HF 5% was used for the heterojunctions, since it was the purest product obtained among the three different reactions. The characterization techniques for the analysis of the MXene and the heterojunctions were XRD, Uv-Vis, SEM, and mass spectroscopy for the analysis of the photocatalytic performances.I documenti in UNITESI sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
