Metal oxide-based semiconductor photocatalysis has attracted much attention in recent years. In the cutting
edge of efficient photocatalysis, various synthetic and modification strategies of oxides on the nanometer scale have
evolved for surface tuning properties. Thus, it is interesting to study recent progresses in the development of surface tuned
metal oxide-based nanomaterials as efficient photocatalysts. In this work, special importance, especially facile and feasible
approaches is given to develop surface tuned, high thermal stability and hierarchically structured novel ZnO/Zn nanocrystallites.
We also investigated the impact of both aggregation phenomenon and photoinduced charge separation in metal
oxide nanoparticles. The photocatalytic ability of nano ZnO/Zn on the photodegradation of methylene blue under UV irradiation
was investigated in aqueous solution. The result obtained in this work is a key to the rational design of
mesoporous nanoparticle networks and helps to engineer composite nanomaterials for photocatalysis.
