In this study, we report the combination of porosification and doping strategy to improve the catalytic activity of NiCo₂O₄-based electrocatalysts for HER and OER. A facile porosification method was proposed and demonstrated by annealing the NiCo₂O₄ nanosheets in a reductive atmosphere to synthesize porous NiCo₂O₄ nanosheets. In order to further improve the catalytic activity for HER and OER, the porous NiCo₂O₄ nanosheets were doped with P and Fe, respectively, which tailored the electronic structure of the electrocatalysts, improved the intrinsic catalytic activity, and increased the number of active sites. HER or OER experiments were performed on the porous P-NiCo₂O₄ nanosheets or the porous NiCo_1.5Fe_0.5O₄ nanosheets, which required an overpotential of 160 mV or 222 mV to deliver a current density of 10 mA/cm², respectively. Furthermore, overall water splitting was achieved using the porous P-NiCo₂O₄ nanosheet cathode and the porous NiCo_2-xFe_xO₄ nanosheet anode with a Faraday Efficiency of 98.22%. The present paper proposes a strategy to fabricate doped porous electrocatalysts with a view to providing insights for the design and synthesis of efficient and inexpensive electrocatalysts for water splitting.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"155 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143430993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, in this study, Bi₂O₃-ZnO/ZnAl₂O₄ composite oxide catalysts were constructed using layered double hydroxides as precursors to enhance the interfacial stability and utilize the synergistic effect of zinc-bismuth dual active sites for the efficient electrocatalytic reduction of CO₂ to formate. The product formate bias current density reached up to 25.8 mA·cm^− 2 at -1.3 V (vs. RHE) in an H-type electrolytic cell and the Faraday efficiency of formate was maintained at about 93% under stability tests up to 14 h, which was superior to most other reported catalysts. In the formation of the Bi₂O₃-ZnO/ZnAl₂O₄ interface, zinc promotes the electroreduction of CO₂ to produce *CO₂⁻ intermediates, while bismuth reduces CO production and improves formic acid selectivity by providing more reactive sites. In addition, the interface between zinc and bismuth optimizes electron and proton flow, helping to maintain a lower energy threshold during the reaction and thus improving catalytic efficiency. This interface engineering approach utilizes zinc-bismuth dual active sites to achieve high selectivity and stability of CO₂ electrocatalytic reduction, providing insights for the development of large-scale efficient CO₂RR catalysts in the future.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"155 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143430994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Produced from fossil resources, jet fuel consumption contributes to rising atmospheric CO₂ levels. Therefore, efficient utilization of renewable resources, such as biomass, to produce jet fuel components is an important step toward building a sustainable society. Hence, structure-modified zeolite catalysts that determine a high selective production of aromatic HCs in the range of jet fuel chemicals from biomass via catalytic pyrolysis were synthesized and engineered in a PyroGC-MS/FID system. The structure-modified catalysts of hierarchical HBeta (HRCHY HBeta) and defect-free nano-sized crystals ZSM-5 (ZSM-5-F) were used to selectively deoxygenate the reactive species in biomass pyrolysis vapors leading to a high production of renewable jet fuels (bio jet fuels; BJFs). The morphology of zeolites were designed for an enhanced diffusion of biomass pyrolysis vapors and upgraded products, in and out of the catalyst, to selectively produce monoaromatic HCs. A comprehensive comparison of the experimental and theoretical results obtained from biomass pyrolysis using the commercial catalyst of HBeta and the structure-modified catalysts of hierarchical HBeta and defect-free ZSM-5 was accomplished in in-situ and ex-situ catalytic configurations. Meanwhile, the catalytic performance of the ZSM-5-F catalyst in the conversion of a biomass pyrolysis oil model into jet fuel chemicals was investigated using a fixed bed catalytic reactor.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"155 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10562-025-04958-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143430991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These investigations, which primarily examine the reduced Mo- and sulfur-terminated edges of MoS₂ slabs, generally categorize the reaction pathways into two types: direct desulfurization (DDS) and hydrogenation-desulfurization (HYD). Traditionally, these models assume that C-S bond cleavage occurs through interactions with edge sulfur atoms, with less attention given to the role of promoter metals like Co. However, our recent work indicates that Co atoms on the S-edges of MoS₂ slabs may play a crucial role in activating and dissociating C-S bonds, particularly through an α-carbon transfer. This process has been identified as key in the desulfurization of small thiols like methanethiol, prompting further investigation into its relevance for aromatic thiols such as thiophene, dibenzothiophene (DBT), and 4,6-dimethyldibenzothiophene (DMDBT). In the DFT calculations presented in this article, we demonstrate that the activation barrier for C-S bond cleavage to Co remains consistent at 1.0-1.1 eV/atom for the unsubstituted aromatic sulfides with a higher 1.67 eV for DMDBT. This oxidative addition mechanism of Co is strongly favored by the presence of dissociated hydrogen on adjacent sites and the aromatic nature of the molecule being desulfurized, while self-desulfurization through this pathway is found to be unfavorable. Our findings provide new insights into the chemistry of promoter atoms in the HDS of heavy aromatic sulfides.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"155 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10562-025-04953-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The preparation conditions could be controlled to render the TiO₂ surface positively charged and the CQDs surface negatively charged.

This study evaluated the effect of structural modifications of LaFeO₃ (LF) and LaMnO₃ (LM) perovskites series on the total oxidation of 2-propanol as a VOC model, a well-known organic solvent. These modifications were performed during synthesis by partially removing the B-site cation or by structural doping in the B-site with another cation (Mn for the LF series and Pd for the LM series). Structural characterization was carried out by XRD and Raman spectroscopy, while the bulk and surface chemical composition were assessed by ICP and XPS, respectively. On the other hand, catalytic activity was performed using a reactivity test with the 2-propanol molecule. The CO-TPR and O₂-TPD measurements were used to characterize the reducibility of the active phase, and the type of oxygen species present in the sample. The catalytic activity results indicated that the modified perovskites showed a difference of 118 °C and 109 °C in the T₉₅ parameter (Temperature at which the conversion of 2-propanol was 95%) relative to pure LF and LM perovskites, respectively.
