      The present study focuses on the synthesis of high energy-density fuel pentacyclotetradecane(PCTD) through cyclodimerization followed by hydrogenolysis of norbornadiene (NBD) over mesoporoussilica-supported Co–Ni-based nanocatalyst. Catalytic materials are synthesized by incipient wetnessimpregnation method using Al-MCM-41, MCM-48 and γ-alumina as supporting materials for Co–Ni metals.The textural properties of the catalyst have been investigated through XRD, TEM and N2 physisorption, andthe parameters concerning the reactivity of the catalyst optimized. The reaction was performed in a single pot(pressure reactor), and the structure of the product was elucidated by using FTIR and NMR techniques. Theoptimum reaction parameters (catalyst, temperature, and pressure) were developed to produce a yield of ≥85%. The physicochemical properties such as calorific value (10754 cal./g), density (1.08 g/cc), etc. wereevaluated, and these can be utilized for ramjet application.
