    Constructing TiO2/g-C3N4/Single-Walled Carbon Nanotube Hydrogel for Synergistic Solar Evaporation and Photocatalytic Organic Pollutant

    Junxiao Qiu1,2, Sanmei Liu3,4,*

    Journal of Polymer Materials, Vol.41, No.4, pp. 315-327, 2024, DOI:10.32604/jpm.2024.057951 - 16 December 2024

    Abstract Integration of solar-driven interfacial evaporation and photocatalysis is one of the most promising technologies for generating fresh water and removing pollutants. In this work, TiO2/g-C3N4 photocatalysis is loaded on a hydrogel containing single-walled carbon nanotube (SWCNT). Due to the excellent water evaporation channel of hydrogel and the excellent photothermal conversion performance of SWCNT, as well as the good visible light absorption ability of TiO2/g-C3N4, TiO2/g-C3N4/SWCNT hydrogel exhibits good hydrothermal evaporation and photocatalytic activity. The optimum water evaporation rate of 1.43 kg m−2 h−1. In particular, the optimized TiO2/g-C3N4/SWCNT hydrogel can also remove more than 90% methylene blue (MB) More > Graphic Abstract

    Journal of Renewable Materials, Vol.10, No.3, pp. 653-663, 2022, DOI:10.32604/jrm.2022.018556 - 28 September 2021

    Abstract Hydrogen production through solar energy is one of the most important pathways to meet the growing demand of renewable energy, and photocatalyst participation in solar hydrolytic hydrogen production has received great attention in recent years in terms of low cost, high efficiency, and flexible design. Particularly, g-C3N4 (Graphitic-like carbon nitride material), as a unique material, can catalyze the hydrogen production process by completing the separation and transmission of charge. The easily adjustable pore structure/surface area, dimension, band-gap modulation and defect have shown great potential for hydrogen production from water cracking. In this review, the most recent More > Graphic Abstract
