Formation of SiO₂@C–Ni magnetic nanotubes with excellent performance in 4-nitrophenol reduction

Dalton Transactions (2022)

Yuqin Jin Jing Zheng Linyu Zhu Xue‐Bo Yin Min Zhang

A facile and rational strategy for immobilizing nickel nanoparticles (Ni NPs) on silica nanotubes (SiO2@C-Ni) was developed via the Stöber method, nickel ion mediated dopamine polymerization and carbonization treatment, coupled with removal of the template of one-dimensional (1D) MnO2 nanowires (NWs). The as-prepared SiO2@C-Ni nanotubes show vast interior space with a large specific surface area and an open channel, which offer a spacious transport channel for molecular diffusion and electron transfer. Consequently, SiO2@C-Ni nanotubes exhibited outstanding catalytic efficiency and excellent stability for 4-nitrophenol (4-NP) reduction. Their superior catalytic activity could be ascribed to the high coverage of Ni NPs and the tubular structure of the obtained SiO2@C-Ni, by which the silica nanotubes enhanced the accessibility of the active sites and increased the mass transfer. This facile and controllable strategy may introduce a new avenue for designing metal NP-supported composites with high dispersion for diverse applications.

Rational Design of Well-Dispersed Co Supported Magnetic N-Doped Carbon Nanotube for High Catalytic Activity Toward Reduction of 4-Nitrophenol

SSRN Electronic Journal (2022)

Hong Du Jing Zheng Yi Mao Wentao Pan Yan Zhang

Heterogeneous catalysts with controllable interface structures are of great importance to demonstrate the relationship between structure and property. Herein, magnetic Nitrogen-doped carbon nanotubes with Co nanoparticles (Fe 3 O 4 @C-Co) were prepared by employing ZIF-67 as a template. Due to the unique structures, the obtained Fe 3 O 4 @C-Co composites improved the dispersion of Co nanoparticles (NPs), diminished the Co leaching, and promoted the catalytic activity. The plentiful nitrogen improved electronic conductivity and brought additional active sites. The resulting Fe 3 O 4 @C-Co implies outstanding catalytic ability towards the reduction of 4-nitrophenol. The synergistic effect between the hollow nanotube and the fine dispersed Co NPs within Fe 3 O 4 @C-Co offered an excellent catalytic efficiency. Furthermore, this obtained Co-based magnetic catalysts maintained outstanding catalytic activity after five cycles with negligible loss of Co NPs. More particularly, this achievement open a new avenue to the targeted design of well-defined nanocatalysts for practical applications in environmental remediation.

In Site Generation of Well‐Dispersed Ag₃PO₄ NPs on Protein‐Inorganic Hybrid Nanoflowers with Enhanced Catalytic Performance

ChemistrySelect (2022)

Chunxiao Ji Jing Zheng Yuqin Jin Xue‐Bo Yin Suping Han

Abstract Developing environmental‐friendly and high‐performance catalysts hold excellent prospects for pollution control. Herein, a novel nanocatalyst is successfully prepared through a facile in‐situ deposition method upon bridging copper phosphate and the protein, which allowing uniform Ag 3 PO 4 NPs to be immobilized on both inner and outer hierarchical nanoflowers. Results show that the fabricated hierarchical flower‐like architecture of Cu 3 (PO 4 ) 2 @BSA@Ag 3 PO 4 composite demonstrated superior catalytic performance for the hydrogenation of 4‐nitrophenol. Moreover, the hybrid nanoflowers hold a high conversion rate (around 95.4 %) and recycling stability over five reaction cycles. Therefore, such a convenient, economical and green approach to synthesize recyclable nanoflowers possesses broad application potential for the treatment of agricultural and industrial wastewater.
