Resumo: Molybdenum disulfide is a widely used material for environmental remediation in view of its excellent adsorption capacity, which is attributed to the active sulfur sites on the MoS2 surface. In addition, it presents advantages in comparison with other photocatalysts, such as high photocatalytic activity, low toxicity and good ability to remove organic and inorganic contaminants. In this review we will present the different methods of preparing molybdenum disulfide from mechanical, chemical, electrochemical exfoliation and the hydrothermal, solvothermal and chemical vapor deposition methods. It will be also addressed about  its superior properties such as the adsorption capacities for different types of heavy metals in solution, the types of photocatalytic degradation from the comparison with MoS2 -  based adsorbents with other adsorbents, as well as the adsorption mechanisms and the factors that affect this process, such as the pH and temperature of the solution, contact time, types of contaminants as well as the influence of other ions present in the solution that can hinder the adsorption process. The association of MoS2 with compounds based on graphene oxide and derived from nitrogen, titanium oxide and associations with bismuth and silver introduces advantage of increasing the material's ability to be explored as an adsorbent. Moreover, it is reported about the removal efficiency of the different associations of molybdenum disulfide against the different types of contaminants as well as the different factors that affect the overall efficiency.

Además, tiene ventajas en comparación con otros fotocatalizadores, como por ejemplo debido a su alta actividad fotocatalítica, baja toxicidad y buena capacidad para eliminar contaminantes orgánicos e inorgánicos. En esta revisión presentaremos los diferentes métodos de preparación de disulfuro de molibdeno a partir de exfoliación mecánica, química, electroquímica y los métodos de deposición de vapor hidrotermal, solvotermal y químico. También abordaremos sus propiedades como las capacidades de adsorción para diferentes tipos de metales pesados en solución, los tipos de degradación fotocatalítica a partir de la comparación de adsorbentes basados en MoS2 con otros adsorbentes, los mecanismos de adsorción y los factores que afectan este proceso, tales como el pH y la temperatura de la solución, el tiempo de contacto, los tipos de contaminantes y la influencia de otros iones presentes en la solución que pueden dificultar el proceso de adsorción. Otro proceso a reportar se refiere a la asociación entre MoS2 y otros compuestos, como el óxido de grafeno y compuestos derivados de nitrógeno, óxido de titanio y asociaciones con bismuto y plata, con la principal ventaja de incrementar la capacidad de adoración del material. Como conclusión, hablaremos de la eficiencia de remoción de las diferentes asociaciones de disulfuro de molibdeno frente a los diferentes tipos de contaminantes, así como de los diferentes factores que influyen en esta eficiencia.O dissulfeto de molibdênio é um material amplamente utilizado para remediação ambiental tendo em vista sua excelente capacidade de adsorção, que é atribuída principalmente aos sítios ativos de enxofre na superfície do MoS2. Além disso, este material possui vantagens quando comparado com outros fotocatalisadores, como por exemplo por alta atividade fotocatalítica, baixa toxicidade e boa capacidade de remoção de contaminantes orgânicos e inorgânicos. Nesta revisão apresentaremos os diferentes métodos de preparação do dissulfeto de molibdênio a partir da esfoliação mecânica, química, eletroquímica e os métodos hidrotérmico, solvotérmico e de deposição de vapor químico. Abordaremos ainda suas propriedades tais como as capacidades de adsorção para diferentes tipos de metais pesados em solução, os tipos de degradação fotocatalítica a partir da comparação dos adsorventes a base de MoS2 com outros adsorventes, os mecanismos de adsorção e os fatores que afetam esse processo, como o pH e temperatura da solução, tempo de contato, tipos de contaminantes e a influência de outros íons presentes em solução que podem atrapalhar o processo de adsorção. Outro processo a ser reportado se refere à associação entre o MoS2 e outros compostos, como óxido de grafeno e compostos derivados do nitrogênio, óxido de titânio e associações com bismuto e prata, tendo como principal vantagem o aumento da capacidade de adsorção do material. Como conclusão, será tratado sobre a eficiência de remoção das diferentes associações do dissulfeto de molibdênio frente aos diferentes tipos de contaminantes assim como os diversos fatores que influenciam nesta eficiência.  Research, Society and Development2021-03-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1318710.33448/rsd-v10i3.13187Research, Society and Development; Vol. 10 No. 3; e12410313187Research, Society and Development; Vol. 10 Núm. 3; e12410313187Research, Society and Development; v. 10 n. 3; e124103131872525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/13187/11809Copyright (c) 2021 Carlos Alves do Nascimento Filho ; Helinando Pequeno de Oliveirahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessNascimento Filho , Carlos Alves do Oliveira, Helinando Pequeno de 2021-03-28T12:03:35Zoai:ojs.pkp.sfu.ca:article/13187Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:34:35.465119Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
