Engineering of HO-Zn-N2 Active Sites in Zeolitic Imidazolate Frameworks for Enhanced (Photo)Electrocatalytic Hydrogen Evolution

Context and Methodology

This dataset contains the primary experimental and theoretical data supporting the research article published in Angewandte Chemie (DOI: 10.1002/anie.202419913; 10.1002/ange.202419913).

The files provide the raw and processed data used to characterize the local coordination environment, surface electronic states, and electrochemical performance of the synthesized materials, specifically focusing on the Hydrogen Evolution Reaction (HER). Supporting Density Functional Theory (DFT) calculations are also included. For detailed synthesis protocols, experimental setups, and comprehensive discussion of these results, please refer to the original publication and its Supplementary Information.
