Effective wastewater treatment is essential for mitigating organic pollutants, such as dyes and antibiotics. In this study, the enhancement of niobium pentoxide (Nb 2 O 5 ) nanostructures via molybdenum (Mo) doping to improve adsorption efficiency, selectivity, reusability investigated. Mo doping, successfully confirmed by X‐ray diffraction, energy‐dispersive spectroscopy, photoelectron demonstrates effective integration into Nb lattice, inducing lattice expansion modifying its structural surface properties. Mo‐doped exhibits increased capacities methylene blue (MB) crystal violet (CV), improving from 26.9 17.0 (undoped) 35.4 44.8 mg g −1 , respectively. contrast, Congo red tetracycline decrease 31.6 36.8 16.7 32.0 Isotherm modeling shows Langmuir‐type with maximum 48.6 MB 52.4 CV. Point zero charge analysis indicates improved cationic dye while recyclability tests demonstrate that can retain over 96% capacity after five cycles. thermodynamic studies, an exothermic spontaneous process revealed, pseudo‐second‐order kinetics confirming chemisorption dominant mechanism. these findings, established a highly material applications.

Pharmaceutical pollutants in wastewater can be effectively degraded by heterogeneous photocatalytic processes (HPP); under light irradiation, these methods use semiconductor photocatalysts to produce reactive oxygen species (ROS), which oxidize and mineralize organic (OPs) into innocuous byproducts. Reactant transport the photocatalyst surface, reactant adsorption, charge carrier formation separation, redox reactions, product desorption are all part of mechanisms. This review article analyzes compares various approaches used prepare photocatalysts. The composition, morphology, crystallinity, production scale, influence synthesis technique selection. While hydrothermal, microwave-assisted, sonochemical, mechanochemical provide greater variety synthesising diverse with varying compositions, morphologies, surface characteristics, flame hydrolysis is appropriate for large-scale TiO2 Because it regulates photocatalyst's charge, electrolytic solution's pH significant processes. Within a certain range, an increase temperature generally results continuous breakdown efficacy; beyond that, rate decomposition decreases. These findings besides giving researchers broad overview current status HP process we believe will also inform its future applications advancements.

Nos últimos anos, a busca por energias alternativas renováveis se intensificou devido à crescente preocupação com os problemas ambientais associados ao uso dos combustíveis fósseis. O biodiesel surge como uma alternativa promissora, caracterizando-se fonte de energia renovável potencial para substituir convencionais. A sua produção apresenta flexibilidade em termos diversidade matérias-primas e gera emissões reduzidas gases. Para viabilizar essa transição energética, é imprescindível o desenvolvimento processos que sejam mesmo tempo eficientes economicamente viáveis, otimizando custos aumentando eficiência do processamento. Nesse cenário, catalisadores base nióbio destacam-se suas propriedades físico-químicas singulares, alta resistência condições extremas temperatura, elevada atividade catalítica acidez capacidade reutilização, tornando-os ideais aplicação na biodiesel. Uma revisão sistemática foi conduzida analisar catalisador, abrangendo um período seis anos (2020-2025) utilizando dados científica Science Direct. levantamento revelou suportados diferentes segmentos, ênfase Após triagem seleção criteriosa artigos, 37 estudos foram considerados relevantes discussão final. Esses trabalhos evidenciam opção sustentável eficiente biocombustíveis porém pouca literatura disponível esse direcionamento, destacando seu papel no avanço da tecnologia mais limpos vantajosos.
