However, the photocatalysts are still constrained by issues such as limited surface active sites, excessive charge carrier recombination, and poor visible light consumption. Herein, bismuth oxybromide (BiOBr) nanoplate embedded g-C3N4 heterojunction photocatalyst was effectively fabricated via a one-pot room temperature self-association technique. Then, numerous strategies were used to figure out how the building of the heterojunction photocatalysts affected their ability to eliminate different pollutants. Under direct sunshine exposure, 20 % BiOBr/g-C3N4 (BCN-20) was able to degrade 97.6 % of RhB and 98.6 % of MB in 80 min and also reduced 95 % Cr(VI) after 90 min. Moreover, the degradation efficiency and reduction capability of BCN-20 heterojunction is superior compared to both g-C3N4 and BiOBr. Additionally, the BCN-20 photocatalyst has much greater stability. The increased activity may be due to the tighter interface interaction, the higher surface area, and the very strong separation of photo-induced electrons and holes. Based on experimental findings, a Z-scheme framework has been suggested to elucidate the charge carrier transfer process. The primary active substances for the photocatalytic breakdown of RhB and MB dye, according to the radical trapping tests, are holes (h+) and superoxide radicals (•O2−). Also, for photocatalytic reduction of Cr (VI), the primary active species are •O2− and electron (e−).

XRD demonstrated that as the spin rate increased from 1000 to 3000 rpm, the film's crystallinity decreased from 35.66 to 15.74 nm. Increasing the rotation speeds from 2500 to 3000 rpm caused a shift towards lower 2θ values in the peak (101) of Mg doped ZnO thin films due to lattice contraction. SEM analysis reveals that spin coating speed results in a smoother surface, featuring a wrinkle pattern (2500 and 3000 rpm). The thickness of the thin films decreases significantly, from 608 nm to 240 nm. AFM measurements indicated a decrease in surface roughness from 78.12 nm to 18.9 nm. The optical properties of the higher spin coating speed show 96% transmittance. UV–Vis spectroscopy shows the absorption edge in the range 330–340 nm. The energy bandgap value increased from 3.13 eV to 3.37 eV. The vibrational peaks at 435 cm⁻1 and 350 cm⁻1 in the Raman spectra confirm the wurtzite structure of ZnO and the multi-phonon process.

The carrier concentration increased from 0.96 × 1014 cm−3 to 5.66 × 1014 cm−3, and the resistivity values decreased from 9.45 × 103 Ω cm to 1.10 × 103 Ω cm in Mg doped ZnO films.
