Compared with traditional metal pipes, polyethylene (PE) pipes have unique advantages in terms of corrosion resistance, surface friction resistance, and service life. In this paper, aiming at an enhancement of anti-scaling and corrosion-resistant properties, as well as increased mechanical properties, PE nanocomposites have been prepared by the introduction of modified carbon nanotubes (m-CNTs) into the PE matrix. To improve the interface compatibility of the composites, the CNTs were treated with reactive tetrabutyl titanate after nitric acid oxidation, which brings about uniform dispersion of the CNTs and intimate interface interaction. As the m-CNT fraction increases, the PE crystallinity displays a slight increase. Polarized microscopy shows that the scaling on the surface of the composite material is obviously reduced compared with pure PE, because the surface free energy of the composite material decreases. Moreover, due to the good dispersion, the composites show enhanced mechanical properties. That is, by adding 1.10 wt% CNTs, the tensile stress and impact toughness of the composites are 20.76 MPa and 37.89 kJ m−2, respectively, increases of 15.0% and 11.9% compared with pure PE. This paper supports the idea that the crystallinity of the PE matrix can be improved by adding CNTs, thereby increasing the corrosion resistance and anti-scaling properties. This work can provide inspiration for using the methods of scale inhibition and corrosion resistance in polymer nanocomposites.Keywords: Carbon nanotube; Nanocomposite; Polyethylene; Anti-scaling; Corrosion-resistant.","PeriodicalId":29808,"journal":{"name":"Industrial Chemistry & Materials","volume":" 1","pages":" 154-164"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/im/d3im00031a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116737273","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}

Manganese oxide-based (MnOx) materials, especially MnO2, have become promising non-precious metal electrocatalysts for the OER under acidic conditions due to the good trade-off between catalytic activity and stability. This paper reviews the recent progress of MnO2-based materials to catalyze the OER through either the traditional adsorbent formation mechanism (AEM) or the emerging lattice-oxygen-mediated mechanism (LOM). Pure manganese dioxide OER catalysts with different crystalline structures and morphologies are summarized, while MnO2-based composite structures are also discussed, and the application of MnO2-based catalysts in PEMWEs is summarized.

However, unsatisfactory cyclability and poor conductivity have been recognized as the key limitations to LDH performance. To overcome these obstacles, constructing hybrid materials as well as designing porous nanoarchitectures are efficient approaches. Herein, through controlling the sulfide ion concentration during the synthesis of CuS nanosheets and adjusting the amount of urea in the synthesis of flower-like ZnCo-LDH structures, an optimized sample with an exclusive porous texture was fabricated on nickel foam (NF) (identified as NF@CS10-ZC-LDH4) via two-step hydrothermal routes and then employed as a binder-less electrode for a hybrid supercapacitor. The as-fabricated nanoarchitectures provide efficient electron-ion transport channels and preserve the structural integrity during prolonged periods of cycling, which resulted in fantastic supercapacitive properties with a capacity of 1270.5 C g−1 and excellent cyclability (remaining at 90.7% after 7000 cycles). Furthermore, we fabricated a hybrid supercapacitor (NF@CS10-ZC-LDH4//NF@AC) with NF@CS10-ZC-LDH4 as a cathode electrode and activated carbon (AC)-covered NF as an anode electrode. The energy density of NF@CS10-ZC-LDH4//NF@AC was high, at 62.4 W h kg−1 with a power density of 810.4 W kg−1 and splendid cyclability of 88.4%. This innovative study offers valuable inspiration for the synthesis of electrode materials to be used in hybrid supercapacitors.Keywords: Layered double hydroxides; Flower-like ZnCo-LDH; Hybrid supercapacitors; CuS nanosheets.","PeriodicalId":29808,"journal":{"name":"Industrial Chemistry & Materials","volume":" 3","pages":" 443-457"},"PeriodicalIF":0.0,"publicationDate":"2023-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2023/im/d3im00027c?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49995213","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}

Meanwhile, the high price of Pt-based catalysts, which are now widely used commercially, has raised the cost of PEMFCs. Therefore, non-noble metal ORR catalysts as alternatives to Pt-based group metals (PGM) have attracted much attention. However, there is still a big gap between the performance of non-noble metal catalysts and commercial Pt/C catalysts in acidic environment. Recently, it has been realized that the performance of catalysts is closely related to the structure of catalytically active sites. Inspired by this, in this review, we firstly introduced the development and breakthrough of non-noble metals as activity sites. We then briefly summarized their catalytic mechanisms, and put forward some suggestions on how to improve the activity and stability of non-noble metal ORR catalysts.Keywords: ORR; Non-noble metal single atom catalysts; Active site; Fuel cell.","PeriodicalId":29808,"journal":{"name":"Industrial Chemistry & Materials","volume":" 3","pages":" 388-409"},"PeriodicalIF":0.0,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2023/im/d3im00002h?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49994730","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}

The present review covers several of the most important homogeneously catalyzed processes and technologies which are currently used or have the potential to produce fine and bulk chemicals from 1,3-butadiene. As an example, palladium-catalyzed telomerizations provide valuable chemicals through the selective dimerization of 1,3-dienes with the simultaneous addition of various nucleophiles, which can be used for the synthesis of 1-octene, 1-octanol, and various lactones. On the other hand, direct carbonylation allows the selective introduction of functional groups onto 1,3-dienes, such as carbonyl, carboxyl or ester groups. The key to success in achieving these industrially relevant conversions of 1,3-butadiene was mainly the development of innovative efficient catalysts. We hope this review will make readers familiar with the industrially applied and relevant transformations of 1,3-butadiene and inspire them to further explore new and advanced systems.Keywords: 1,3-Butadiene; Industrial chemistry; Carbonylation reaction; Bulk chemicals; Telomerization.","PeriodicalId":29808,"journal":{"name":"Industrial Chemistry & Materials","volume":" 2","pages":" 155-174"},"PeriodicalIF":0.0,"publicationDate":"2023-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2023/im/d3im00009e?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49994179","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}
