Catalytic hydrolysis of chemical hydrides with the use of NaBH<sub>4</sub> is a safe and efficient way to provide hydrogen fuel for new energy vehicles and portable electronics devices. In this work we have prepared a series of Co<sub>1-x</sub>Cu<sub>x</sub>MoO<sub>4</sub> hybrids by hydrothermal method. The resultant hybrids were characterized to confirm the structural and physicalchemical properties by analytical techniques (FTIR, XRD, FE-SEM). Catalytic activity of Co<sub>1-x</sub>Cu<sub>x</sub>MoO<sub>4</sub> hybrids were investigated by hydrolysis of NaBH4. It is found that there is synergetic effect between CoMoO<sub>4</sub> and CuMoO<sub>4</sub>. Among those Co<sub>0.9</sub>Cu<sub>0.1</sub>MoO<sub>4</sub> shown highest catalytic activity of 301.72 H<sub>2</sub> g<sub>cat</sub><sup>-1</sup>min<sup>-1</sup> within 10 min. at room temperature. Additionally, Co<sub>0.9</sub>Cu<sub>0.1</sub>MoO<sub>4</sub> catalyst shown good recyclability making it a robust catalyst for hydrolysis of NaBH<sub>4</sub>.

Electrochromic (EC) smart window is a new technology that is capable of changing from transparent to opaque and has the potential in energy saving applications. In this work, we have prepared a series of WO3 based hybrids by different synthesis method. In EC smart windows, WO3 is the key element where it is responsible for the colouring and bleaching of the device. Therefore, the properties of WO3 with different dopants will affect the EC performance. In this work, WO3 films were deposited on tin doped indium oxide (ITO) coated glasses. The WO3 film thicknesses were varied by means of number of deposited layers. Their morphological, structural, optical and EC properties were characterised by FE-SEM, XRD, UV-Vis. spectra, (CV) and (CA) measurements, respectively.

Present work reports the facile synthesis of Co1-xCuxMoO<sub>4</sub> hierarchical hybrids by hydrothermal method. The hybrids were characterized by various analytical techniques to confirm their structural and physical-chemical properties. With the increase in Cu ratio with respect to Co the morphology of these hierarchical hybrids varied significantly from irregular microsphere to marigold microspheres. Catalytic activity of hierarchical hybrids were investigated by hydrolysis of NaBH<sub>4</sub> and outstanding catalytic activity was found for marigold-like Co0.9Cu0.1 MoO<sub>4</sub> catalyst with a H<sub>2</sub> generation rate of 1005.7 ml H2·gcat-1 min-1. Also, catalysts mass loading, reusability tests were studied to confirm for their minimum catalyst loading and stability.
