Multi-Layer Kesterite-Based Photocathodes for Nh Photosynthesis from N Reduction Reaction.

The necessity of new methods to substitute the Haber-Bosch process in the NH synthesis, generating fewer greenhouse gases, and dispensing less energy, drove the investigation of the photoelectrocatalytic approach in the N reduction reaction (N2RR). For that, this work presents the synthesis and characterization of the layered CZTSSe/CdS/TiO photocathode decorated with Pt nanoparticles for application in NH production using the photoelectrocatalysis technique. The CZTSSe/CdS/TiO-Pt characterization showed a well-designed and stable photocatalyst synthesized layer by layer with an important contribution of the Pt nanoparticles for the catalyst performance, improving the photocurrent density and the charge transfer.
