As an environmentally functional material, zeolite solids can strongly adsorb and decompose harmful indoor gases, such as formaldehyde, to improve the home environment. Rare earth sulfide as a nontoxic and environmentally friendly pigment with good coloring performance is one of the promising choices to replace toxic cadmium- and lead-based pigments. In this work, multifunctional red γ-Ce2S3 pigments coated with microporous zeolite solids have been prepared by a hydrothermal method. The preparation process is safe and environmentally friendly. The fabricated composite solids not only absorb gas and water but also absorb water by microporous structures. The solids also show a stable red color, self-cleaning, and radiative cooling. Our results suggest that the multifunctional red cerium sulfide pigment-coated zeolite solids can be applied in color display, temperature and humidity control, and air purification.
Over the past decades, graphene oxide (GO) and its composites with organic and inorganic components have gradually become one of the most popular carbon nanomaterials , on account of multitudinous advantages, including great conductivity, excellent thermal stability and large specific surface area. In particular, the magnetic GO based composites have been extensively investigated for various applications owing to their combined advantages from both GO and magnetic nanoparticles . Although many strategies have been developed for preparation of magnetic GO based composites, a facile and efficient strategy is still rarely reported. In this work, we developed a direct, ultrafast, green and non-toxic strategy for scalable production of GO–Fe 3 O 4 hybrids for the first time. Compared with conventional preparation methods, this strategy only requires a simple one-step reaction and would produce no pollutants in the whole reaction process. Furthermore, it could convincingly demonstrate the successful preparation of GO–Fe 3 O 4 hybrids with outstanding properties through a series of characterization techniques. Finally, the outstanding performance of GO–Fe 3 O 4 hybrids in adsorption experiments has been also demonstrated. Results indicated that these GO–Fe 3 O 4 composites are potentially used for environmental adsorption.
