Flexible cotton fabrics/PDA/BiOBr composite photocatalyst using bioinspired polydopamine as electron transfer mediators for dye degradation and Cr(VI) reduction under visible light

ZIF‐8 Derived ZnO Decorated with Polydopamine and Au Nanoparticles for Efficient Photocatalytic Degradation of Rhodamine B

“…Figure 4e displayed N 1s spectrum with one peak at 399.4 eV, which might be attributed to NÀ H band of amine group in PDA. [12] The C 1s spectrum was shown in Figure 4f. The strong peak at 284.6 eV was assigned Scheme 1.…”

“…In addition, PDA, forming through self-polymerization of dopamine under weak basic condition, is usually used as the surface modification layer due to its strong adhesive ability, which would help stabilize the formed metal nanoparticles. [10] What's more, PDA can improve the light harvesting under a broadband spectrum from the UV to visible region [11] and promote the charges separation, [12] leading to the improved photocatalytic performance. PDA utilized as surface modifier on photocatalytic materials has attracted extensive attention such as TiO 2 @PDA, [13] ZnO@PDA, [14] BiVO 4 @PDA, [15] and PDA/g-C 3 N 4 .…”

High Performance of Multifunctional Cotton Fabrics Modified with TiO2, Fe, Ag-doped TiO2 and Graphene Oxide Nanomaterials towards Antimicrobial and Adsorption Removal of Methylene Blue Dye

“…1. The XRD pattern of pure cotton fabric has main characteristic diffraction peaks at 14.5°, 16.5°, 22.4°, and 33.85° due to the characteristic diffraction planes of (1 -10), (110), ( 200) and (004), respectively, characterizing to cellulose I structure [31][32][33]. The XRD of all the treated samples exhibit similar peaks to that of uncoated cotton but with different intensities.…”

Photocatalytic Degradation of Organic Dyes with Magnetically Separable PANI/Fe3O4 Composite under Both UV and Visible‐light Irradiation

“…Compared with traditional methods such as adsorption, biodegradation (bacteria), coagulation, the hydrogenation of organic dyes, photocatalytic degradation of dyes exhibits great promise in environmental remediation thanks to the utilization of the solar spectrum (both UV and visible light), low cost and lack of harmful by-products process. [4] Various semiconductor photocatalysts such as doped CdS, [5] TiO 2 , [6] BiOBr, [7] CdO, [8] Fe 2 O 3 , [9] Cu 2 O, [10] NiO, [11] WO 3 , [12] SnO [13] and ZnO [14] have been utilized to clean hazardous organic dyes from wastewater. [15] It has been noted that those semiconductors were activated mostly under ultraviolet-light irradiation, which requires the high energy-consuming UV light source (only include 4 % of sunlight), restricting the use of sunlight light sources and generating greater costs of purification.…”
