Abstract:
 
The Ph.D. thesis delved deeper into the issues related to the fabrication of dense metal inorganic composite membranes using rate enhanced electroless plating processes.  The thesis first addressed the identification of low cost inorganic precursor formulation to achieve a compatible porous ceramic support of an average pore size of 150 - 220 nm. Thereby, the thesis addressed the optimality of sonication and surfactant as scalable rate enhancement techniques during Ni ceramic composite membrane fabrication with electroless plating technique.   Eventually, the thesis addressed the optimality of metal and reducing agent concentration and reducing agent contacting pattern for surfactant induced electroless plating process for dense Ni ceramic composite membrane fabrication. Subsequently, the thesis addressed the optimality of surfactant contacting pattern (bulk mode for surfactant and sonication assisted electroless plating and dropwise for surfactant induced electroless plating) and concentration for surfactant induced and surfactant and sonication induced electroless plating processes to fabricate dense Ni ceramic composite membranes. With these insights, the Ph.D. thesis finally targeted the process an parametric optimality for the inexpensive fabrication of dense Pd ceramic composite membrane fabrication. The research findings have been filed as an Indian patent.
 
All in all the thesis addressed an experimental framework for the comparative assessment of optimal electroless plating processes and associated parameters for dense Ni and Pd ceramic composite membrane fabrication. The obtained research findings are very much useful to assist the large scale fabrication of dense ceramic composite membranes using electroless plating process and its variants in terms of rate enhanced electroless plating processes.
