Publication date: 25 July 2018Source: Journal of Industrial and Engineering Chemistry, Volume 63Author(s): Gourav Mishra, Mausumi MukhopadhyayAbstractNovel halloysite nanotubes (HNTs) embedded poly(vinyl chloride) ultrafiltration (UF) membrane (PVC/HNTs) were prepared and examined by FTIR, FEG-SEM-EDX, TEM, and SPM. In PVC/HNTs 1 and PVC/HNTs 2 membrane, HNTs were finely distributed and membrane surface became smooth. Pure water flux of the prepared membrane increased from 127.33 L m−2 h−1 for PVC/HNTs 0 membrane to 212.22 L m−2 h−1 for PVC/HNTs 2 membrane. Flux recover...

One-pot synthesis of Pt–Sn bimetallic mesoporous alumina catalysts with worm-like pore structure for n-butane dehydrogenation
Publication date: 25 July 2018Source: Journal of Industrial and Engineering Chemistry, Volume 63Author(s): Prakash Natarajan, Hassnain Abbas Khan, Sungho Yoon, Kwang-Deog JungAbstractFive PtSn catalysts with different PtSn particle sizes were prepared using one-pot and co-impregnation methods for n-butane dehydrogenation. The turnover frequency (TOF) of the prepared catalysts is proportional to the PtSn metal particle size, while the selectivity to n-butenes is inversely proportional to that. The PtSn(OMSO) catalyst with a worm-like pore structure has the smallest PtSn particle size and the largest metal surface area, whic...

Tannin-mediated assembly of gold–titanium oxide hybrid nanoparticles for plasmonic photochemical applications
Publication date: 25 July 2018Source: Journal of Industrial and Engineering Chemistry, Volume 63Author(s): Ho Yeon Son, Hwiseok Jun, Kyeong Rak Kim, Cheol Am Hong, Yoon Sung NamAbstractPlasmonic nanostructures have received increasing attention for photochemical applications due to high light absorptivity, tunability, sensitivity, and robustness. However, the short lifetime of hot electrons limits their efficient extraction, requiring the well-defined assembly of neighboring functional materials (e.g., electron filters and catalysts) along with the plasmonic nanostructures. Here we report the polyphenol-mediated assembly o...

Au ion-mediated self-assembled tyrosine-rich peptide nanostructure embedded with gold nanoparticle satellites
We report a gold ion-mediated self-assembled tyrosine-rich peptide (TRP) spherical nanostructure with gold nanoparticle (AuNP) satellites (YC7@Ausat). We clarified that non-reduced gold ions, coordinated with TPRs are not only one another critical driving force for TRP spherical self-assembly together with instant thermal transition, but also play a key role to determine the spherical shape of TRP nanostructures. Furthermore, the pH and the concentrations (buffer, peptides, and AuCl4−) are considered as important parameters to obtain optimal YC7@Ausat nanostructures. In addition, plasmonic properties of YC7@Ausat nan...
