The article discusses environmental pollution and energy needs, introduces the application of photocatalysts in addressing water pollution and energy challenges, focuses on the performance and synthesis processes of SnO2 and SnO2-based photocatalysts, as well as the research progress of Z-scheme SnO2 photocatalysts.
Not just people, but all living species, desire a clean and green environment to live a happy and healthy life. However, in our ever-increasingly congested world, it is quite challenging. Excessive deforestation, factory smoke, various chemical compounds, agricultural chemicals, etc. all pollute our environment severely. Some of its adverse consequences include water contamination and a shortage of energy sup-plies. In recent times, photocatalysts have sparked tremendous attention as a means of addressing energy demands as well as environmental challenges (water pollution). For this, SnO2 and SnO2 based photocat-alysts have gained a great attention due to its good photocatalytic ability. In the same way, SnO2-based Z -scheme photocatalysts has extended significant interest to address these concerns due to its strong pho-tocatalytic characteristics, energy savings, eco-friendliness, and lack of adverse health effects. Though, the photocatalytic effectiveness of conventional SnO2 semiconductors, with their shortcomings, falls well short of the real requirements. The current review emphasizes on admirable properties and several syn-thesis processes of SnO2 which make it an ideal photocatalyst. This study also stresses the fundamental shortcomings of SnO2 that restrict its utilization. The central section of this review is concentrated on SnO2-based Z-scheme photocatalysts and most recent significant research modification of Z-scheme SnO2-based photocatalysts. The photocatalytic applications of Z-scheme SnO2-based photocatalysts for pollutants removal, energy conversion, and water splitting are also summarized. In conclusion, we have addressed the challenges and future exploration of SnO2-based photocatalysts with a Z-scheme hetero-junction type for pollutant degradation and energy conversion.
