“…These industries dispose of large amounts of untreated pollutants, chemicals, and dyes into water bodies, thereby harming humans and aquatic species. 1 These dyes are toxic, highly water-soluble, chemically stable, carcinogenic, and non-biodegradable. These dyes obstruct sunlight penetration, leading to a decrease in the rate of photosynthesis and causing aquatic species to be deprived of oxygen.…”

“…The unmatched charge behaviors, that is, attenuated charge generation and reinforced charge transfer often result in a limited increase of available charge carriers or even a negative effect in the presence of the excessive amount of carbon. , Alternatively, numerous pathways have also been urbanized to intensify the charge recombination, separation, and generation of S-gC 3 N 4 , for example, constructing agglomerate-type structured S-gC 3 N 4 to attain better light-harvesting ability. The doping of a heteroatom, such as nitrogen, into S-gC 3 N 4 is able to expand the wavelength of the solar light absorption ability while connecting other photo-sensitizers onto S-gC 3 N 4 offers efficient generation of electrons additionally. The charge recombination, separation, and generation efficiencies are improved as compared to S-gC 3 N 4 , which profit from humanizing the overall solar-to-value added chemical efficiency. Although some noteworthy progress in the amplification of charge recombination, separation, and generation steps, the synergistic exploitation of a few steps is rarely found in the literature. , Mainly, it is tranquil demanding but extremely desirable to obtain well-matched charge recombination, separation, and generation in the S-gC 3 N 4 -based photocatalyst.…”

“…Desorción de productos de reacción 5. Eliminación de productos de reacción de la región de interfaz Óxidos de metal como el óxido de titanio (TiO2), óxido de zinc (ZnO), óxido de tungsteno (WO3), óxido de cerio (CeO2), óxido de estaño (SnO2), óxido de rutenio (RuO2), óxido de manganeso (MnO2), óxido de cobalto (Co3O4), óxido de níquel (NiO), óxido de hierro (Fe2O3), entre otros, han sido muy utilizados como fotocatalizadores en la fotocatálisis heterogénea [46], [51]- [53], debido a una favorable banda prohibida y a que exhiben propiedades electrónicas, ópticas, térmicas, químicas y mecánicas adecuadas [54]. Estos óxidos, además de ser estables bajo distintas condiciones de reacción y a la capacidad de generar portadores de carga al ser excitados a una determinada longitud de onda, presentan un elevado desempeño fotocatalítico [38], [55].…”

“…Se han reportado un gran número de aplicaciones para diferentes tipos de nanoestructuras, entre las que se encuentra la fotocatálisis heterogénea, en la cual, han sido utilizadas nanoestructuras de óxidos de metal, debido a que las propiedades de estos materiales se pueden ajustar fácilmente. También tiene alta: reactividad química, capacidad de difusión, gran número de sitios activos y banda prohibida adecuada debido al efecto de confinamiento cuántico [54].…”
