This study evaluates the cost and environmental impacts of a newly developed scalable Pt/STO catalyst production, which includes the synthesis of the STO support and the deposition of Pt onto the support. This two-step synthesis plays a significant role in assessing the commercial feasibility of the catalyst, while energy consumption during the process plays an important role in its environmental impacts. The CatCost and the Research and Development Greenhouse Gases, Regulated Emissions, and Energy use in Technologies (R&D GREET) models were used, respectively, to perform techno-economic analysis (TEA) and life cycle analysis (LCA) of the newly developed catalyst. The TEA showed that the raw materials, accounting for approximately 76% of the total operation cost, has a profound effect on the estimated catalyst cost, mainly due to the platinum precursor. The LCA findings indicated that the catalyst production generates greenhouse gas (GHG) emissions of 66 kg CO2e per kg, primarily due to the use of solvents and electricity in the process. The sensitivity analysis indicated that the total operating costs (OpEX), platinum precursor cost, and spent catalyst value (SCV) significantly impact the cost of the synthesized catalyst. Additionally, adopting solvent recovery strategies and using renewable electricity can reduce the GHG emissions of catalyst production to 29 kg CO2e per kg.","PeriodicalId":66,"journal":{"name":"Catalysis Science & Technology","volume":" 15","pages":" 4419-4429"},"PeriodicalIF":4.4,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/cy/d5cy00189g?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144714600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most visible light-mediated systems currently employ expensive noble metals (e.g. Ru, Ir) and difficult-to-recycle small-molecule organic dyes. In this work, two novel, cost-effective, and easily separable polymeric photosensitizers were successfully synthesized and employed as metal-free heterogeneous photocatalysts for the α-oxidation of N-aryltetrahydroisoquinolines (model reaction 1) and methylation of quinoxalin-2(1H)-ones (model reaction 2), respectively. All reactions proceeded smoothly upon irradiation with an LED under aerobic conditions at room temperature and were easily scaled up. The photocatalysts can be readily recovered and reused (up to 10 cycles) without significant loss of catalytic activity, indicating a very promising potential for practical applications.

The experiments showed that catalysts with higher Zn content (e.g., Co0.1Zn0.9) exhibited higher CH4 selectivity (29.32%), while the high Co ratio (e.g., Co0.9Zn0.1) significantly enhanced the CO generation rate (3.13 μmol g−1 h−1). Characterization by N2 adsorption, XRD, XPS, UV-vis DRS, and in situ DRIFTS revealed that the metal ratio affected the CO2 adsorption and electron transport efficiency by modulating the catalyst specific surface area (1213 → 555 m2 g−1), the band gap width (3.53 → 3.39 eV), and the distribution of the surface-active sites. The DFT calculations further revealed the synergistic effect of Co/Zn: high Zn content lowers the *CHO generation barrier (3.45 eV) and promotes the CH4 pathway, while the Co center enhances CO2 activation.

However, innovative methodologies focusing on the design and synthesis of novel materials remain essential to effectively tackle persistent challenges such as material degradation, high overpotentials, low conductivity, inferior cycling performance, elevated resistance, and high production costs. Working along these lines, we report a simplistic gram-scale synthesis, characterization, and excellent electrochemical behavior of a Zn(II)-based coordination polymer (COP) abbreviated as Zn(DAB). It has been obtained in quantitative yields through a facile one-pot reaction between N4-ligand, 3,3′-diaminobenzidine (DAB), and Zn(II) ions, derived from Zn(OAc)2·2H2O, at room temperature. The proposed structure of the COP was established through a series of standard spectroscopic and electron microscopic analyses. These methods unveiled the self-assembly of indefinitely long coordination strands, resulting in a two-dimensional (2D) layered structure. Zn(DAB), when probed for its electrochemical characteristics, reveals exemplary results. The material showed a high specific capacitance of 2091.4 F g−1, calculated at 1 A g−1 with 92% retention over 5000 charge–discharge cycles. Additionally, the COP also exhibited a subservient overpotential of 263 mV at a current density of 10 mA cm−2 for the hydrogen evolution reaction. These results highlight the promising potential of Zn(DAB) as a multifunctional electrode material for sustainable energy applications.","PeriodicalId":66,"journal":{"name":"Catalysis Science & Technology","volume":" 15","pages":" 4528-4541"},"PeriodicalIF":4.4,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/cy/d5cy00282f?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144714617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These include terpenoid alcohols such as geraniol and prenol, which are readily available from renewable, bio-derived feedstocks. Furthermore, the reaction is facilitated using aluminosilicates, including zeolites. It was found that Y-type zeolites were highly effective at mediating the coupling with furan, giving the 2-alkylated furan high yields. While various allylic alcohols were effective for this reaction, the identity of the furan proved to have a drastic impact on reactivity.

Among various compositions, the 9AT catalyst (APM : TiO2 = 9 : 1 w/w) exhibited the highest TC removal efficiency. Under optimal conditions (1.2 g L−1 catalyst dose, pH 7.1, and 20 mg L−1 initial TC concentration), 9AT achieved 96.5% TC degradation. Here, TiO2 acted as a coating/stabilizing material to protect APM, which was only stabilized under acidic conditions and dissolved even in a near-neutral solution.

Transformation products (TPs) and plausible degradation pathways were identified. The developed catalyst demonstrated excellent stability, maintaining over 65% efficiency after eight cycles. Additionally, 9AT proved effective in degrading TC in real wastewater, underscoring its practical applicability.

The metal sulfides exhibit distinct OER activities based on their metallic components. Further, density functional theory calculations show a strong correlation between their OER activities and unoccupied d-band centers, similar to the case of metal oxides.
