“…Similar results were observed in [37]. Moreover, the broad absorption band located around 1381 cm -1 is attributed to asymmetric C=O (Carbonyl) stretching vibration modes [38]. The band observed around 841 cm -1 is ascribed to the C-H out-of-plane bending for Zinc oxide nanoparticles (ZnO-NPs).…”

“…For the reference material ZnO, the decomposition was over 90%. The results for these materials are higher than for the ZnO-Tb material used by Ghrib et al (48%) (Ghrib et al 2021). However, according to the study by Migdadi et al (Migdadi et al 2022) for the ZnO/CuO material, containing 10% mas.…”

The study analyses nanotechnology advances in the synthesis of catalytic nanozymes that mimic enzymatic properties, but are also inorganic nanomaterials. It compares Zn-Mn-Cu multioxide and Mn-Cu multioxide nanomaterials in the role of nanozymes and photocatalysts, in the decomposition of trypan blue dye. The study showed that Zn-Mn-Cu multioxide nanoxide has activity as a peroxidase-like nanozyme (100 mUnit/mL) and achieves 75% dye degradation as a photocatalyst under UV light. While Mn-Cu multioxide shows enhanced photocatalysis under visible light (45% degradation), consistent with its biocatalytic hydrolysis mechanism. In addition, both materials showed biocatalytic activity in the degradation of trypan blue dye (25%), without an additional light source. Further investigation of these dual nanozyme activities may reveal new solutions for their environmental use.

“…The solid‐state chemical reaction method consists of four steps, namely, diffusion, reaction, nucleation, and growth [79]. This method has the advantages of simple processes such as synthesis, high yield, high selectivity, uniform particle size distribution, controllable size, and less pollution [80].…”

Zinc oxide (ZnO) is a promising material with a diverse range of applications, spanning gas sensing, photonics, photovoltaics, energy conversion, water splitting, photocatalysis, and transparent trapping. However, ZnO limited responsiveness to visible light affected to low photogenerated electron‐hole pairs (charge), low quantum efficiency, and high recombination of charge. In this review, we are addressing innovative strategies, including incorporation rare earth elements as a trap of electron to reduce recombination charge via ZnO doping from analysis 118 referenced sources. We found that hydrothermal shows very good methods for boosting efficiency up to 100 % within 60‐min. We found that for rare‐earth metals La and Ce as a doping show highest efficiency up to 100 % within 120 min irradiations, means that efficient as a trap for reducing recombination of charge. The potential of rare earth doped ZnO will enhance photogenerated electron‐hole pairs, catalyzing the generation of radical atoms via oxidation and reduction reactions. This review encapsulates the most current findings, it serves as a valuable resource for scholars seeking to advance their understanding of rare earth doped ZnO photocatalysts and developing innovative photocatalytic technologies.
