A ∼15-nm-thick Pt·MoO3−x film was prepared by one-pot electrodeposition at −0.8 V for 1 ms. Due to considerably different solute concentrations, the content of Pt atoms in the electrode-posited composite electrocatalyst is low. No Pt crystals or islands were observed on the flat Pt·MoO3−x films, indicating that Pt atoms were homogeneously dispersed within the MoO3−x thin film. The catalytic performance and physicochemical features of Pt·MoO3−x as a HER electrocatalyst were characterized. The results showed that our Pt·MoO3−x film exhibits 23- and 11-times higher current density than Pt and MoO3−x electrodeposited individually under the same conditions, respectively. It was found that the dramatic enhancement in the HER performance was principally due to the abundant oxygen defects. The use of the developed one-pot electrodeposition and doping method can potentially be extended to various catalytically active metal oxides or hydroxides for enhanced performance in various energy storage and conversion applications.</div>","PeriodicalId":572,"journal":{"name":"Frontiers of Materials Science","volume":"16 3","pages":""},"PeriodicalIF":2.7,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46090670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, it is proposed to grow one-dimensional Heusler alloy nanostructures (1D-HA-NSs) by magnetron sputtering plus anodic aluminum oxide (AAO) template. Nanowires with different shapes, amorphous-coated (AC) nanowires and nanotubes were successfully grown for several Heusler alloys. AC nanowires are the unique products of our method. Heusler alloy nanotubes are reported for the first time. The one-dimensional nanostructures grow on the surface of the AAO substrate rather than in the holes.

In addition to the high surface area-to-volume ratio, they exhibit excellent scalability in synthesis, controllable shape and size, facile surface modification, inertness, stability, and unique optical and magnetic properties. However, only a limited number of inorganic nanocarriers have been so far approved for clinical applications due to burst drug release, poor target specificity, and toxicity. To overcome these barriers, understanding the principles involved in loading therapeutic and imaging molecules into these nanoparticles (NPs) and the strategies employed in enhancing sustainability and targetability of the resultant complexes and ensuring the release of the payloads in extracellular and intracellular compartments of the target site is of paramount importance. Therefore, we will shed light on various loading mechanisms harnessed for different inorganic NPs, particularly involving physical entrapment into porous/hollow nanostructures, ionic interactions with native and surface-modified NPs, covalent bonding to surface-functionalized nanomaterials, hydrophobic binding, affinity-based interactions, and intercalation through co-precipitation or anion exchange reaction.</div>","PeriodicalId":572,"journal":{"name":"Frontiers of Materials Science","volume":"16 3","pages":""},"PeriodicalIF":2.7,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11706-022-0604-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47511057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present work, we used a reactive solid consisting of a mixture of 90 wt.% of NH3BH3 and 10 wt.% of palladium chloride, because the mixture reacts in a fast and exothermic way while releasing H2 and generating catalytic Pd0. We took advantage of such reactivity to trap and convert CO2 (7 bar), knowing besides that Pd0 is a CO2 hydrogenation catalyst. The operation (i.e. stage 1) was effective: BNH polymers, and B—O, C=O, C—O, and C—H bonds (like in BOCH3 and BOOCH groups) were identified. We then (in stage 2) pyrolyzed the as-obtained solid at 1250 °C and washed it with water. In doing so, we isolated cyclotriboric acid H3B3O6 (stemming from B2O3 formed at 1250 °C), hexagonal boron nitride, and graphitic carbon. In conclusion, the stage 1 showed that CO2 can be ‘trapped’ and converted, resulting in the formation of BOCH3 and BOOCH groups (possible sources of methanol and formic acid), and the stage 2 showed that CO2 transforms into graphitic carbon.</div>","PeriodicalId":572,"journal":{"name":"Frontiers of Materials Science","volume":"16 2","pages":""},"PeriodicalIF":2.7,"publicationDate":"2022-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43872712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
