0D/1D CdSe@CdS QDs/GONRs nanocatalyst for efficient photoelectrochemical water splitting

CdSe@CdS/GONRs nanocomposites were synthesized with different content of graphene nanoribbons (GONRs = 1, 2, and 5%) via the microwave method. Comprehensive characterization, including XRD, FESEM, EDX, HRTEM, and DRS, confirmed the structure and properties of nanocomposites. The CdSe@CdS/GONRs (5) p...

Description
Summary:CdSe@CdS/GONRs nanocomposites were synthesized with different content of graphene nanoribbons (GONRs = 1, 2, and 5%) via the microwave method. Comprehensive characterization, including XRD, FESEM, EDX, HRTEM, and DRS, confirmed the structure and properties of nanocomposites. The CdSe@CdS/GONRs (5) photocatalyst exhibits good hydrogen evolution reaction (HER) properties in comparison to the others. Low onset overpotential of 93 mV, slight Tafel slope of 69 mV dec −1 , and excellent stability of 2000s in acidic media are its advantages. The synergistic effect of GONRs and CdSe@CdS enhances visible light photoelectrochemical water splitting related to the effectual separation of the photoproduced charge carriers.
