Expression of concern: Designing a novel visible-light-driven heterostructure Ni–ZnO/S-g-C3N4 photocatalyst for coloured pollutant degradation

TL;DR

This paper addresses concerns about a study on a new photocatalyst for breaking down colored pollutants using visible light.

Contribution

The paper raises concerns about the reliability or validity of the original study's claims and findings.

Findings

The original study claimed a novel Ni–ZnO/S-g-C3N4 photocatalyst for visible-light-driven degradation of pollutants.

This expression of concern questions the accuracy or reproducibility of the reported results.

It highlights the need for further verification of the experimental claims.
