“…[Image: see text] Bismuth vanadate/coconut fiber (BiVO(4)/CF) composites were synthesized by coprecipitation and calcination methods. All catalysts used in this work were prepared by a simple coprecipitation method and fully characterized by means of XRD, SEM-EDS, PL, BET N(2) adsorption, zeta potential, and UV–vis DRS. …”

“…A novel type of porous Co(3)O(4) hollow nanoprism (HNP) was successfully prepared using tetragonal cobalt acetate hydroxide [Co(5)(OH)(2)(OAc)(8)·2H(2)O] as precursor by a facile solvothermal process and a subsequent calcination treatment. The morphology and structure of the Co(3)O(4) HNPs were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), powder X-ray diffraction (XRD) and N(2) adsorption–desorption measurements. …”

“…The hollow cavities derived from the core–shell-like CaCO(3)@polydopamine were creatively introduced into the 3D absorber to significantly improve the absorption performance. The sample calcined at 700 °C exhibited the most outstanding microwave absorption performance, with minimal reflection loss up to −50.80 dB at 17.52 GHz with a rare thickness of only 1.5 mm when filler loading was 35% in paraffin matrix. …”
