Extensive investigations have been conducted to explore the photocatalytic degradation of economically harmful substances, employing a wide range of photocatalytic materials and various approaches. The successful degradation and elimination of persistent pollutants from aquatic environments remain a challenging task, requiring further advancements in efficiency. Hereby, we present a ZnBi 2 O 4 /ZIF-67 derived hollow Co 3 O 4 decorated reduced graphene oxide (rGO) hybrid nanocatalyst (ZnBi 2 O 4 /ZIF-Co 3 O 4 /rGO:ZCG) fabricated through a facile thermal treatment approach. The synthesized ZCG heterojunction demonstrated exceptional catalytic effectiveness for the photocatalytic reduction of Cr(VI) and photocatalytic degradation of rhodamine B (RhB) when exposed to visible radiation. A comprehensive array of analytical techniques was employed to thoroughly characterize the produced photocatalyst. In the realm of photocatalytic efficiency, ZCG-4 beats all other catalytic materials in eradicating model contaminants. Based on our outcomes, the ZCG-4 nanohybrid can reduce 97.4% (20 ppm, 60 min) of Cr(VI) to Cr(III), and degraded 92.5% (20 ppm, 120 min) of RhB, which is more superior to pristine and doublet nanohybrids. The improved photocatalytic Cr(VI) reduction and RhB degradation may be attributed to the beneficial synergistic interaction between the rGO, ZnBi 2 O 4 , and ZIF-Co 3 O 4 nanocomponents in the nanohybrid. Based on the data from the various experiments, we infer that the as-prepared photocatalyst functions via a Z-scheme charge transfer channelization mechanism, exhibiting a significant suppression of the photogenerated electron−hole pairs charge recombination. In addition, after five cycles of recycling, there is no obvious decline in the ZCG photocatalytic ability to catalyze Cr(VI) and RhB. This research demonstrates that the as-obtained ZCG nanocatalysts have significant potential for effectively addressing the issue of environmental remediation of toxic pollutants.

Organic pollutants in water pose significant challenges for water treatment due to their harmful effects and resistance to conventional methods. The rapid increase in industrial wastewater discharge has heightened the need for effective pollutant degradation techniques. Photo‐Fenton technology, an advanced oxidation process, has gained attention for its ability to degrade a wide range of organic contaminants in water. Developing high‐performance photo‐Fenton catalysts is therefore crucial. Graphitic carbon nitride (g‐C3N4) stands out in this field due to its suitable energy band structure, stable properties, and simple synthesis process. However, its application is limited by a low specific surface area, narrow light absorption, and high recombination rate of photogenerated carriers. This review provides a concise overview of current research on g‐C3N4 in photo‐Fenton technology, covering synthesis methods, modifications, and the mechanisms enhancing its photo‐Fenton activity. It also highlights key factors affecting g‐C3N4’s effectiveness in photo‐Fenton reactions and discusses recent advancements in its applications. The review concludes with an analysis of existing challenges and potential future directions for g‐C3N4‐based photo‐Fenton catalysts, offering theoretical insights to advance their industrial use in wastewater treatment.

This work proposes an original method that reveals the transformation dynamics of nanosized Bi films into semiconductor films of bismuth oxide (Bi2O3) and the factors affecting the low‐energy cold plasma on the electro‐optical properties of Bi2O3. In the plasma microreactor with a photosensitive GaAs:Cr electrode, the transformed Bi films 400–1100 nm thick are analyzed by X‐ray diffraction to determine the crystal structure of Bi2O3 and by an electron probe microanalyzer to explore the evolution of the composition. The morphological properties of the Bi films exposed to electron–ion flow are examined by processing the scanning electron microscope images. It is found that as a result of the combined effect of photoactive illumination, charged particles, and active plasma components: 1) an absorption spectrum of a new substance is formed in the range λ = 330–1100 nm; 2) the optical width of the bandgap of the resulting substance is Eg ≈ 3 eV, which satisfactorily coincides with the width of the bandgap of Bi2O3; and 3) to overcome the potential barrier and formation of semiconducting Bi2O3 film energy is required, which is provided by the combined kinetic energy of electrons and negatively charged oxygen ions bombarding on the Bi film.
