Metal-organic frameworks, a class of highly crystalline porous materials, have gained intense research interest in material science in the last decade due to its intriguing chemistry and unique properties which lead to diverse applications. There are different methods for the development of MOF thin film in lab scale and its fabrication in electronic devices. However, the harsh reaction conditions, prolonged synthesis time, complex experimental setup etc. limit its application. Here, the electrochemical synthesis offers the advantages of mild reaction conditions, real time tuning of applied potential, short reaction time etc. which make the selective deposition of MOF on various conducting substrates facile. In this review, we focus on the direct electrochemical synthesis of MOF with emphasis on anodic and cathodic electrodeposition. The two different synthetic methods are explained in detail with a detailed review on its progress since its development. The electrosynthesis of MOF is still in its infancy stage and therefore the challenges and future perspectives associated with it are also discussed.

Bimetallic metal organic frameworks (BMOFs) are a class of crystalline solids and their structure comprises two metal ions in the lattice. BMOFs show a synergistic effect of two metal centres and enhanced properties compared to MOFs. By controlling the composition and relative distribution of two metal ions in the lattice the structure, morphology, and topology of BMOFs could be regulated resulting in an improvement in the tunability of pore structure, activity, and selectivity. Thus, developing BMOFs and BMOF incorporated membranes for applications such as adsorption, separation, catalysis, and sensing is a promising strategy to mitigate environmental pollution and address the looming energy crisis. Herein we present an overview of recent advancements in the area of BMOFs and a comprehensive review of BMOF incorporated membranes reported to date. The scope, challenges as well as future perspectives for BMOFs and BMOF incorporated membranes are presented.[a] K.
