“…There is a slight decrease of the decomposition ratio after recycling the catalyst for 3 times, indicating the remarkable stability of its pyrocatalytic decomposition performance for RhB dye [57]. Furthermore, as a magnetic material, BiFeO 3 also has been reported with the excellent recyclable ability [58], which makes the recycling process of the catalyst convenient. Both the remarkable stability and the excellent recyclability of BiFeO 3 / g-C 3 N 4 heterostructure catalyst are helpful to its practical application in dye decomposition.…”

The BiFeO3/g-C3N4 heterostructure, which is fabricated via a simple mixing-calcining method, benefits the significant enhancement of the pyrocatalytic performance. With the growth of g-C3N4 content in the heterostructure pyrocatalysts from 0 to 25%, the decomposition ratio of Rhodamine B (RhB) dye after 18 cold-hot temperature fluctuation (25–65 °C) cycles increases at first and then decreases, reaching a maximum value of ∼94.2% at 10% while that of the pure BiFeO3 is ∼67.7%. The enhanced dye decomposition may be due to the generation of the internal electric field which strengthens the separation of the positive and negative carriers and further accelerates their migrations. The intermediate products in the pyrocatalytic reaction also have been detected and confirmed, which proves the key role of the pyroelectric effect in realizing the dye decomposition using BiFeO3/g-C3N4 heterostructure catalyst. The pyroelectric BiFeO3/g-C3N4 heterostructure shows the potential application in pyrocatalytically degrading dye wastewater.

The use of solar energy to catalyze the photo-driven processes has attracted tremendous attention from the scientific community because of its great potential to address energy and environmental issues. In this regard, several attempts have been made by researchers to design and develop different materials with enhanced photocatalytic efficiencies. This Review comprehensively summarizes the recent reports on perovskite oxide based photocatalysts for organic pollutant degradation, water splitting, carbon dioxide conversion, and nitrogen fixation along with the basic understanding of involved mechanisms, current trends and advances in the field. The different design, synthesis, and development strategies have been discussed in detail to provide a comprehensive view of materials’ fabrication that influences their photocatalytic properties. Subsequently, the insights from recent reports on different perovskite oxide based materials, including simple oxides, mixed oxides, and layered perovskite oxides, are provided for the above-mentioned photocatalytic applications in a detailed manner. Finally, a summary of photocatalytic applications and a perspective on future research direction have been discussed. Based on the research progress in this field, it is highly anticipated that the photocatalytic systems, comprising perovskite oxide materials along with groundbreaking technologies for large-scale realization of these processes, can be established in the near future to address the energy and environment-oriented challenges.
