They introduced OH<sup>&#8211;<\/sup>\/I substitution strategy to fabricate iodine-defects engineering BiOI film. The superficial color of the 3D-printed substrates ordinally changed from gloss white to brownish yellow, dark yellow, and light yellow, which was ascribed to the change of band gap caused by iodine-defect engineering film.<\/p>\n<p dir=\"ltr\">During the growing process of films, iodine spaces were introduced into the BiOI crystals, increasing BiOI internal electric field and\u00a0electron density\u00a0and improving photoinduced carrier separation and transmission efficiency. Iodine-defects\u00a0engineering BiOI exhibited smaller grain size, higher specific surface area, electronegativity, photoelectric response and photocatalytic activity than stoichiometry BiOI.<\/p>\n<p dir=\"ltr\"><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone size-full wp-image-85195\" src=\"https:\/\/polymervapooshesh.ir\/wp-content\/uploads\/2023\/05\/65456-3.png\" alt=\"\" width=\"737\" height=\"416\" srcset=\"https:\/\/polymervapooshesh.ir\/wp-content\/uploads\/2023\/05\/65456-3.png 737w, https:\/\/polymervapooshesh.ir\/wp-content\/uploads\/2023\/05\/65456-3-300x169.png 300w, https:\/\/polymervapooshesh.ir\/wp-content\/uploads\/2023\/05\/65456-3-390x220.png 390w, https:\/\/polymervapooshesh.ir\/wp-content\/uploads\/2023\/05\/65456-3-600x339.png 600w\" sizes=\"(max-width: 737px) 100vw, 737px\" \/><\/p>\n<p dir=\"ltr\">The researchers proposed that Bi<sup>3+<\/sup>\u00a0firstly adsorbed on polymers to construct the active grown sites of the film.
