We investigated the influence of ZnO surface character on oxidation activity by depositing ∼1.6 nm and ∼3.2 nm Pt particles on nonpolar ZnO nanorod and Zn-polar ZnO nanopyramid surfaces. Pt particle size reduction enhances CO conversion rates up to 200 % under O₂-lean oxidation conditions whereas a switch from the nanopyramid to nanorod ZnO morphology leads only to 20–40 % higher oxidation rates. According to DRIFTS analyses the ZnO surface effect can be ascribed to additional Pt sites on the nanorod catalysts that enable stronger CO activation. The attenuation of the Pt particle size effect in O₂-rich reaction mixtures suggests that it originates from the availability of more Pt sites for O₂ activation on smaller particles. Thus, CO conversion rates over Pt/ZnO catalysts can be markedly improved by optimizing their nanostructural design.</div></div>","PeriodicalId":243,"journal":{"name":"Applied Catalysis A: General","volume":"699 ","pages":"Article 120265"},"PeriodicalIF":4.7,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143834180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This critical review provides a systematic summary and guidance on the catalytic conversion of waste biolipids and lignocellulose into biofuels via hydro-conversion in respect of metal catalysts and reaction mechanisms. First, five typical metal catalysts are reviewed, including reducible metal oxides, metal sulfides, metal phosphides, metal carbides, and metal nitrides. Among them, reducible metal oxides and metal sulfides are widely reported due to their efficient hydrodeoxygenation (HDO) activity. The design and preparation of catalysts from noble and non-noble metals, especially the rational design of catalyst active sites, are explored. For metal sulfides, novel in situ synthesis methods are summarized, especially in HDO reactions using oil-soluble precursors, such as ionic liquids with highly designable moieties. The importance of support is then discussed, particularly the positive effects of morphology, synergistic metal-support interactions, and surface acidity on HDO performance. Subsequently, the reaction mechanism of biomass hydrogenation treatment to produce biofuels was explored in detail using methyl palmitate as a biolipid model compound and cellobiose as cellulose and hemicellulose model compound. We also introduce two typical processes for hydro-conversion of biomass to biofuels involving three general units: pre-treatment unit, HDO unit, and separation unit. Finally, this review provides a summary and insights into catalyst design, one-pot isomerization, operando characterization, and reaction process development.</div></div>","PeriodicalId":243,"journal":{"name":"Applied Catalysis A: General","volume":"699 ","pages":"Article 120278"},"PeriodicalIF":4.7,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143824521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
