In recent times, the environmental and pure water crisis requires many types of scientific evaluation to handle the issues caused by different pharmaceutical drugs. The current work involves the synthesis of ternary hybrid nanomaterials based on Ti3C2MXene–BiFeO3 (BFO)–ZnO and their applications as photocatalysts for the disintegration of antacids. The introduction of the two-dimensional (2D) MXene layer in the BFO–ZnO heterostructures not only creates additional reaction hotspots but also enhances charge-transport properties through favorable band alignments at the interface as revealed by scanning tunneling spectroscopy. Therefore, the ternary nanocomposite device exhibits enhanced photocurrent and improved photocatalytic degradation performance. The degradation efficiency of the most commercially used antacid, pantoprazole, can reach up to 92.05% and reveals good stability and an apparent quantum yield of 1.7%. Furthermore, possible degradation pathways of the antacids and degradation mechanisms were proposed by identifying degraded products using high-resolution mass spectrometry. This work realizes the objective of formulating a metal oxide-based hybrid nano-photocatalyst supported on a 2D MXene, which provides an efficient way to prepare low-cost and high-efficiency heterojunctions to disintegrate pharmaceutical contaminants from real water matrices.

“…Different nanostructures also have an influence on the performance of MEGs, which is worth further investigation. Metal compound nanomaterials have been successfully used in many fields, such as optoelectronic, thermoelectric, and piezoelectric devices [56][57][58][59][60]. With the knowledge about preparation methods and fundamental physical and chemical properties, it is expected that more metal compounds will be used in the field of MEGs and help to create devices with higher performance.…”

The consumption of energy is an important resource that cannot be ignored in modern society. Non-renewable forms of energy, such as coal, natural gas, and oil, have always been important strategic resources and are always facing a crisis of shortage. Therefore, there is an urgent need for green renewable forms of energy. As an emerging green energy source, the moist-electric generator (MEG) has been studied in recent years and may become an energy source that can be utilized in daily life. Along with the advancement of technological means, nanoarchitectonics play an important role in MEG devices. This review aims to provide a comprehensive summary of the fundamentals of the MEG from the perspective of different material classifications and to provide guidance for future work in the field of MEGs. The effects of various parameters and structural designs on the output power, recent important literature and works, the mechanism of liquid–solid interactions at the nanoscale, and the application status and further potential of MEG devices are discussed in this review. It is expected that this review may provide valuable knowledge for future MEG research.
