The above-described protocols lay out a complete process for testing particulate photocatalysts, ranging from preparation of the photocatalyst dispersion, the experimental set-up, procedure for irradiation experiments and product quantification, including data analysis. It highlights important parameters that should be controlled (e.g. reaction temperature or irradiation intensity) and points out different pitfalls in the experimental process and interpretation of obtained data. By bringing attention to these points and offering robust procedures to address them, we hope that this work can contribute to the deployment of reproducible and insightful procedures for testing of particulate photocatalysts.
