Here, we report a simple strategy for synthesizing a palladium-based heterostructured electrocatalyst supported on a carbon nitride matrix (PdH-Pd@CN), which exhibits remarkable ORR activity with a half-wave potential of 0.91 V and excellent durability in 0.1 M KOH. Within the heterostructure, hydrogen intercalation expands the Pd lattice, while interstitial hydrogen doping facilitates charge transfer from Pd to H owing to their electronegativity difference. These synergistic effects modulate the electronic structure, thereby enhancing both activity and stability. When employed in Zn-air batteries, PdH-Pd@CN delivers a maximum power density of 176 mW cm− (Liu et al., 2025) and capacity of 805 mAh g− (Sun et al., 2021) Zn. These findings demonstrate the strong potential of PdH-Pd@CN as an efficient ORR electrocatalyst for next-generation metal-air batteries and related energy technologies."}],"status":"public","quality_controlled":"1","article_type":"original","has_accepted_license":"1","month":"01","acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"NanoFab"}],"ddc":["540"],"oa":1,"volume":324,"date_created":"2026-01-25T23:01:39Z","department":[{"_id":"MaIb"}],"publication":"Chemical Engineering Science","_id":"21037","tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"publication_identifier":{"issn":["1873-4405"],"eissn":["0009-2509"]},"PlanS_conform":"1","article_processing_charge":"Yes (in subscription journal)","title":"Hydrogen induced palladium-based heterojunction electrocatalysts to enhance the oxygen reduction reaction performance","oa_version":"Published Version","day":"12","date_published":"2026-01-12T00:00:00Z","year":"2026","intvolume":" 324","doi":"10.1016/j.ces.2026.123348","publisher":"Elsevier","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"OA_place":"publisher","main_file_link":[{"url":"https://doi.org/10.1016/j.ces.2026.123348","open_access":"1"}],"type":"journal_article","publication_status":"epub_ahead","author":[{"last_name":"Shi","first_name":"Changwei","full_name":"Shi, Changwei"},{"last_name":"Horta","id":"03a7e858-01b1-11ec-8b71-99ae6c4a05bc","first_name":"Sharona","full_name":"Horta, Sharona"},{"last_name":"Ibáñez","id":"43C61214-F248-11E8-B48F-1D18A9856A87","first_name":"Maria","full_name":"Ibáñez, Maria","orcid":"0000-0001-5013-2843"},{"first_name":"Tanja","full_name":"Kallio, Tanja","last_name":"Kallio"},{"full_name":"Martínez-Alanis, Paulina R.","first_name":"Paulina R.","last_name":"Martínez-Alanis"},{"full_name":"Wang, Xiang","first_name":"Xiang","last_name":"Wang"},{"first_name":"Andreu","full_name":"Cabot, Andreu","last_name":"Cabot"}]}
