Nowadays, photocatalysis has gained tremendous interest owing to the fact that it can overcome water crisis as well as the environmental issues by utilizing a major source of solar energy. The nanohybrid structures of Gd- and Sn-doped bismuth ferrite (Bi Gd Fe Sn ; BGFSO) with two-dimensional (2D) MXene sheets are synthesized by the coprecipitation method. The 2D sheets have a large surface area, incorporation of which into Bi Gd Fe Sn (BGFSO) nanoparticles provides a path for electrons to flow, which results in large recombination time and thus enhances dye degradation. The BiGdFeSnO/MXene (BGFO-20Sn/MXene) nanohybrid shows 100% degradation of Congo dye from the catalytic solution in 120 min, which is highly efficient for industrial application.
如今，光催化因其能够利用太阳能这一主要能源来克服水危机以及环境问题而备受关注。采用共沉淀法合成了具有二维（2D）MXene片层的钆（Gd）和锡（Sn）掺杂的铋铁氧体（BiGdFeSn；BGFSO）纳米杂化结构。二维片层具有较大的表面积，将其掺入BiGdFeSn（BGFSO）纳米颗粒中为电子流动提供了一条路径，这导致了较长的复合时间，从而增强了染料降解。BiGdFeSnO/MXene（BGFO-20Sn/MXene）纳米杂化物在120分钟内可使催化溶液中的刚果染料100%降解，这对于工业应用而言效率极高。
