In this talk, we will focus on the fabrication of Nano hybrids materials for energy and environmental applications. Especially, the hybrid systems of transition metal oxides/sulfides for photocatalytic and electrocatalytic applications will be briefly presented from our alreayd reported works. The center focus will be the challenges in the hybrid materials in terms of physical and functional characterization. We will connect applied approach with various materials by emphasizing their potential properties in the development of high performance future technologies based on the hybrid materials to sustain the clean energy and environment for sustainable societies.
