Its chemical state and promoting mechanism, however, remain elusive. Here, we study the influence of different anionic counterparts of K (i.e., H- and OH-) on its promoting capability and function in ammonia synthesis catalysis. When potassium is in the form of hydride (KH), it can enhance the ammonia formation rate of the Fe/carbon nanotube (CNT) catalyst by two orders of magnitude; while it is in the form of hydroxide (KOH), the rate increment is only ∼5 times. We show that both KH and KOH can promote N removal from Fe nitride under a hydrogen atmosphere, where an intermediate KNH2 species may form and further be hydrogenated to NH3. Isotopic measurements show that H atoms in KH and KOH are involved in the formation of NH3. For the KH-Fe catalyst, the hydridic H of KH is reductive and may undergo a redox reaction with adsorbed N (Nad) on Fe to form KNHx species and further be hydrogenated to NH3 and create a clean Fe surface for further nitrogen activation. For the KOH-Fe catalyst, the protonic H of KOH may protonate Nad on Fe to form NH3 through the intermediate species of K-Fe-O and KNH2. This work reveals the crucial role of hydrogen in ammonia synthesis catalysis and, moreover, could inspire revisiting of the role of alkali promoters in industrial ammonia synthesis catalysts.","PeriodicalId":36121,"journal":{"name":"The Innovation","volume":"7 10","pages":"101435"},"PeriodicalIF":39.5,"publicationDate":"2026-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13673536/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149216877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A three-stage mixed-effects meta-analysis framework was applied to estimate a nonlinear ERF that links PM2.5 exposure to CKD risk ratio or estimated glomerular filtration rate (eGFR) reduction, by integrating all available evidence via systematic searches. Based on the derived ERF, we quantified the global and national burden of CKD attributable to PM2.5 exposure above 10 μg/m3 from 1990 to 2020. A total of 38 studies on CKD and 16 on eGFR were included. Per 10 μg/m3 increment in PM2.5, the pooled risk ratio of CKD was 1.32 (95% confidence interval [CI]: 1.21-1.43) and the ERF indicated a predominantly log-linear association; the pooled eGFR reduction was 2.115 mL/min/1.73 m2 (95% CI: 0.452-3.777), and the ERF showed a saturated effect of high-concentration exposure. In 2020, PM2.5 exposure was estimated to contribute to 485,000 (95% CI: 370,000-587,000) deaths, 5.77 million (95% CI: 4.51-6.99 million) incident cases, and 243 million (95% CI: 188-294 million) prevalent cases of CKD worldwide. Compared with level-2 risk factors for CKD mortality in the Global Burden of Disease study, PM2.5 ranked first in 1990 and second in 2020, reaching a level of importance comparable to major metabolic risk factors. This study provides robust evidence that PM2.5 is a substantial contributor to the global CKD burden and that clean air action is an urgent and integral CKD prevention.","PeriodicalId":36121,"journal":{"name":"The Innovation","volume":"7 8","pages":"101429"},"PeriodicalIF":39.5,"publicationDate":"2026-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13457180/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148713797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
