A new method for the preparation of Gd-doped SnO2 nanoparticles based on precipitation followed by hydrothermal treatment has been developed. Two different shape series with Gd content were obtained and fully characterized using a wide range methods, including XRD, FTIR, XPS Raman spectroscopy, TEM imaging, SSA evaluation, optical absorption spectra study, luminescence quantum chemical calculations.It was shown that mechanism oriented attachment nanoparticle growth is stimulated during treatment. Quantum computer calculations interaction energies performed role ions in reaction media revealed. study photoluminescence carried out, showing presence blue corresponding to emission oxygen vacancies.Photocatalytic activity when irradiated visible light shown, which explained demonstrated example colored solution organic dye methylene blue. The relation between morphological structural properties their photocatalytic studied detail. high degradation percentage achieved regular commercially available LED lamp spectrum. concept development efficient photocatalysts computational experiments proposed.

Researchers have recently paid a lot of attention to semiconductor photocatalysts, especially ZnO-based heterostructures. Due its availability, robustness, and biocompatibility, ZnO is widely researched material in the fields photocatalysis energy storage. It also environmentally beneficial. However, wide bandgap quick recombination photoinduced electron–hole pairs limit practical utility. To address these issues, many techniques been used, such as doping metal ions creation binary or ternary composites. Recent studies showed that ZnO/CdS heterostructures outperformed bare CdS nanostructures terms photocatalytic performance when exposed visible light. This review largely concentrated on heterostructure production process possible applications including degradation organic pollutants hydrogen evaluation. The importance synthesis engineering controlled morphology was highlighted. In addition, prospective uses realm conceivable photodegradation mechanism were examined. Lastly, heterostructures’ challenges prospects for future discussed.

Synthetic dyes are widely used in various industries, which inevitably leads to increased water pollution. One of the recognized and waste-free techniques for treatment is photocatalytic purification using semiconductor nanoparticles. However, debate on how properties can be tuned through structural morphological parameters nanoparticle synthesis procedures remains open. In present work, an approach regulate UV-light-driven activity spherical SnO2 nanoparticles different demonstrated first time. Complex characterization was provided physicochemical methods with help computational methods. Special attention paid development a protocol oxygen vacancy accounting within computer calculations more realistic modeling interaction energy between surfaces organic dye molecules natures. The photocatalysis mechanism investigated according developed protocol, including study mixture kinetic degradation, dye-photocatalyst complex formation, ratio vacancies defects. It shown that 93% single decomposed 7 min, degradation real sample from Neva River achieved 60% after 40 min. possible establish this proof-of-concept based combination experimental approaches develop strategy rational design photocatalysts promising samples.

Abstract The increasing demand for sustainable and eco-friendly technologies has recently led to the development of green bio-based synthesis methods a broad range nanoparticles (NPs). This is because these are non-toxic, biocompatible, cost-effective. Photosensitive (PSNPs) have gained popularity due their photo-responsive properties. PSNPs also been found be promising nanomaterials with applications in optoelectronics, photocatalysis, photovoltaics, bioimaging, drug delivery, cancer treatment. However, conventional raise concerns about environmental impact. To address challenges, researchers explored alternative approaches PSNPs. review comprehensively evaluates advantages limitations highlights unique properties various fields. It covers general concepts PSNPs, mechanism action, characterization techniques, challenges that not discussed detail previous studies.
