Conductive Polymers‐Confined Metal‐Organic Frameworks with Enhanced Activity for Highly Efficient Photocatalytic CO₂ Reduction

ChemElectroChem (2023)

Xinzuo Fang Sheng Lei Feng Zhiwei Junfei Ou

Abstract Photocatalytic CO 2 reduction to valuable fuels is highly desirable to alleviate global warming and energy crisis. Herein, a stable aluminum‐porphyrin metal‐organic frameworks (MOFs) named Al−PMOF, with wide spectral response, is selected as platforms for the construction of efficient photocatalyst to convert CO 2 into CO. To enhance the activity of pristine Al−PMOF, highly active reaction sites are introduced through metallization of the porphyrin linkers with Cu 2+ . Furthermore, the polymerization of pyrrole in the channel of MOFs is also performed to improve the electron conductivity and narrow the band gap. The polypyrrole offers the conductive network to transfer the light‐generated electrons and thus enhances the efficient charge separation. The calculated electronic density of states based on the density functional theory (DFT) further prove the electron interaction between the polypyrrole and the MOFs, which benefit the enhancement of photocatalytic performance of Al−PMOF.

Permeabilities and Mechanical Properties of Hardened Cement Pastes Modified with Sodium Laurate and Nano Silica

Materials (2020)

Fajun Wang Sheng Lei

In this work, a method of imparting hydrophobicity and high strength to hardened cement paste (HCP) is proposed. Sodium laurate (SL) was used as a hydrophobic modifier and nano silica (NS) as a pozzolan. The HCP was modified by SL and NS simultaneously. HCP modified with different contents of SL and NS was prepared. Surface wettability, micro-structures, chemical composition, and organic structure were systematically studied using contact angle (CA) measurement, scanning electron microscope (SEM) observation, X-ray photoelectron spectroscopy (XPS), and attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), respectively. The surface CA of the sample is 138.5° and has high hydrophobicity. Compared with the reference sample, the water absorption of the modified sample reduced by 96.55%, while the compressive strength only reduced by 6.91%. Therefore, using hydrophobic modifier and reinforcing agent as cement admixture is an effective method to endow concrete with hydrophobicity and high strength at the same time.

Superhydrophobic Hair-Like Nanowire Membrane for the Highly Efficient Separation of Oil/Water Mixtures

Journal of Nanomaterials (2020)

Xinzuo Fang Yufan Liu Sheng Lei Junfei Ou

Water pollution caused by oil leakage and oily wastewater has become a serious environmental problem. Therefore, it is important to develop an efficient material to remove oil from water. Given the cost and efficiency, the membrane with superhydrophobicity is the most used material for the separation of oil/water mixtures. However, many works have been done through modification with a fluorinated reagent, causing high cost and damage to the environment. In this work, a simple and fast two-step method is employed to achieve a superhydrophobic hair-like nanowire membrane. Through the alkali-assisted oxidation process and modification with nonfluorinated low surface energy chemical, the so-obtained membrane (denoted as SHM), with the water contact angle of about 164°, exhibits excellent separation efficiency for binary mixtures of water and oils (toluene, hexane, gasoline, and so on). Meantime, this membrane also exhibits excellent durability and reusability in the long-term separation process, indicating its great potential for practical application in the future.

A Facile Route to Fabricate Superhydrophobic Cu2O Surface for Efficient Oil–Water Separation

Coatings (2019)

Sheng Lei Xinzuo Fang Fajun Wang Mingshan Xue Junfei Ou

The mixture of insoluble organics and water seriously affects human health and environmental safety. Therefore, it is important to develop an efficient material to remove oil from water. In this work, we report a superhydrophobic Cu2O mesh that can effectively separate oil and water. The superhydrophobic Cu2O surface was fabricated by a facile chemical reaction between copper mesh and hydrogen peroxide solution without any low surface reagents treatment. With the advantages of simple operation, short reaction time, and low cost, the as-synthesized superhydrophobic Cu2O mesh has excellent oil–water selectivity for many insoluble organic solvents. In addition, it could be reused for oil–water separation with a high separation ability of above 95%, which demonstrated excellent durability and reusability. We expect that this fabrication technique will have great application prospects in the application of oil–water separation.

Novel All-Natural Material for Oil/Water Separation

Industrial & Engineering Chemistry Research (2019)

Fajun Wang Sheng Lei Junfei Ou Changquan Li Wen Li

Traditional oil/water separation materials were prepared with partial or all nonrenewable raw materials, which would not only increase resource consumption but also cause new environmental pollution after being abandoned. In this work, a superhydrophobic and superoleophilic oil/water separation all-natural material was prepared using a simple and fast emulsion immersing method. The raw materials used including natural sponges and natural vegetable waxes, all of which are renewable. The as-prepared all-natural material can not only absorb various oils from water with high oil absorption capacity, fast oil absorption rate, and good recyclability but also achieve reuse of the absorbed oil by squeezing. In addition, the as-prepared all-natural material exhibits strong stability against cyclic compression, excellent resistance to corrosive aqueous solutions contacting, and organic solvents immersing. Furthermore, the surface wax coating can be easily recycled. This work provides a new method to prepare oil/water separation materials by using all-natural and renewable raw materials.

Facile preparation of TiO₂/acrylic resin superhydrophobic surface with excellent wear resistance

Journal of Applied Polymer Science (2019)

Changquan Li Zhenjun Cao Chan Xie Zi Li Xinzuo Fang

ABSTRACT Superhydrophobic surfaces (SHSs) are widely applied in national defense, industrial, and agricultural production and daily life due to their unique structural characteristics and self‐cleaning properties. In this work, a multilayer structure was obtained on an aluminum substrate using a simple spray method. The acrylic resin was used as a substrate, and the SHS was prepared by combining the acrylic resin with the modified nano‐TiO 2 . The effects of different contents of surface modifier hexadecyltrimethoxysilane (cetyltrimethoxysilane), different spraying times, and different nanometer TiO 2 particle sizes on SHS were studied. The results showed that the optimal modifier content was 16%. When the spraying time is 1 min and the mass ratio of 10‐nm TiO 2 to 100‐nm TiO 2 is 1:1, the contact angle (CA) of the surface is 170.89°, and the sliding angle is 2°. Furthermore, the stability of the SHS under different acid–base conditions, the stability in NaCl solution (3.5 wt %), and the dry friction resistance were further determined. The experimental results show that the prepared samples have certain acid resistance, NaCl resistance, and alkali resistance. After 100 times of dry friction, the CA is still 162.30°, which suggests that the TiO 2 /acrylic resin SHS has excellent dry friction resistance performance. © 2019 Wiley Periodicals, Inc. J. Appl.
