Growing pollution and high energy demand are some of the major issues against humans. Waterpollution is one of the main problems created due to industrial waste and irresponsible human activities. Nowadays, photocatalysis is rising as an efficient alternative to overcome the energy requirement andwater purification, as it can use solar light as a source of energy. Due to some limitations of photocatalysts,such as photocarriers recombination, low surface area, and limited light absorption, modificationssuch as defect modifications, heterojunction can be employed. Out of all, Z-scheme heterojunction is aproficient way to overwhelm the limitation of pristine photocatalysts. To enhance the activity of Zschemephotocatalyst, even more, a dual Z-scheme photocatalytic scheme has been developed in whichtwo Z-scheme based charge transfer occur simultaneously on a ternary photocatalyst. In this review, wehave discussed the different types of dual Z-schemes along with their application in water purificationand finally, we have discussed the future prospects for further research.

Considering the current scenario of rising environmental and energy concerns, engineering of Z-schemephotocatalytic systems is in the spotlight. The prime reason for this includes efficient redox abilities andeffective space separation along with the migration of photoinduced charge carriers over conventionalheterojunction systems. Herein we foreground the stumbling blocks of traditional heterojunctionsystems and enlighten the generations of Z-scheme photocatalysis originating from liquid-phase todirect Z-scheme photocatalytic systems. We provide substantial criteria and selection aspects ofchoosing reductive type photocatalysts as a potential aspirant for the Z-scheme photocatalytic system. AsZ-scheme photocatalytic systems render effective space separation of photogenerated carriers, activespecies generation, wide optical absorption and amended redox ability. We focus on comprehensiveillustration of all solid-state and direct Z-scheme photocatalysts by coupling reductive typephotocatalysts with other semiconductor material and explored their potential for efficacious conversionof solar energy into functional energy. Herein, we aim to provide in-depth and updated criteria forselecting Z-scheme photocatalysts for CO2 reduction, water splitting, and nitrogenfixation. Lastly, thearticle compiles with a conclusive note about future perspectives and challenges accompanying all solidstateand direct Z-scheme Z photocatalysts and their energy conversion applications.
