Best practices for operando hard X-ray absorption spectroscopy

A powerful technique with broad applications, operando X-ray absorption spectroscopy (XAS) is widely used but there is a lack of design and reporting standards. Focusing on water-splitting electrocatalysts, we propose best practices for the reproducibility, replicability and reliability of operando XAS studies.
