Confronting expanding demand for energy and ecological concerns, artificial photosynthesis in reasonably less complex structure to achieve the consequences of natural photosynthesis that is coupling solar powered driven water splitting and CO₂ lessening in a way that dispenses with the requirement for an external, sacrificial electron donor is one of the colossal difficulties for the utilization of renewable energy and a sustainable development. For all intents and purposes, ''CO₂ diminishment'' is more emerging  than ''water splitting'' since it not just adds to worldwide carbon cycling for carbon unbiased natural powers, copying what genuine leaves do (characteristic carbon reduction), additionally mitigating worldwide atmosphere changes. Nonetheless, as CO₂ is a generally dormant and stable exacerbate, its diminishment is entirely testing. The photocatalytic lessening of CO₂ has been generally contemplated for quite a while and additionally water part. For heterogeneous photocatalyst, numerous endeavours still concentrate on TiO₂-based materials while different impetuses, for example, LiNbO₃, ZnGa₂O₄, ALa₄TiO₄ (A=Ca, Sr, and Ba) etc. have additionally been accounted for as of late. Nevertheless, the advance accomplished in this field had not been as sensational as that in water splitting for a few decades in view of the low efficiencies, limited photocatalyst and/or requiring the utilization of sacrificial reducing agents. The study may even manage current gaps inside of the advancement of photocatalytic materials, i.e., the synergy among photocatalytic materials for artificial photosynthesis.
