Herein, an efficient RWGS catalyst is constructed through <em>Enteromorpha prolifera</em>–derived N-rich mesoporous biochar (EPBC) supported atomic-level Cu-Mo₂C clusters (Cu-Mo₂C/EPBC). Unlike traditional activated carbon (AC) supported Cu-Mo₂C particles (Cu-Mo₂C/AC), the Cu-Mo₂C/EPBC not only presents the better graphitization degree and larger specific surface area, but also uniformly and firmly anchors atomic-level Cu-Mo₂C clusters due to the existence of pyridine nitrogen. Furthermore, the pyridine N of Cu-Mo₂C/EPBC strengthens an unblocked electron transfer between Mo₂C and Cu clusters, as verified by X-ray absorption spectroscopy. As a result, the synergistic effect between pyridinic N anchoring and the clusters interaction in Cu-Mo₂C/EPBC facilitates an improved CO selectivity of 99.95% at 500 ​°C compared with traditional Cu-Mo₂C/AC (99.60%), as well as about 3-fold CO₂ conversion rate. Density functional theory calculations confirm that pyridine N-modified carbon activates the local electronic redistribution at Cu-Mo₂C clusters, which contributes to the decreased energy barrier of the transition state of CO∗+O∗+2H∗, thereby triggering the transformation of rate-limited step during the redox pathway. This biomass-derived strategy opens perspective on producing sustainable fuels and building blocks through the RWGS reaction.</div></div>","PeriodicalId":7283,"journal":{"name":"Advanced Powder Materials","volume":"4 1","pages":"Article 100259"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143165289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on this model, some results are demonstrated as below: (1) Although the surface hole density increases when increasing light intensity and applied potential, the hole transfer rate remains linearly proportional to surface hole density on a log-log scale.
