The scientific community around the world is now focusing on the hydrogen economy over the fuel economy. Though hydrogen economy is considered to be superior compared to the fuel economy, it suffers from two major drawbacks such as the production of green hydrogen from sustainable resources and storage and transportation of hydrogen. The use of liquid organic hydrogen carriers (LOHCs) was found to be a superior and much safer way to store and transport hydrogen. In this report, we demonstrated four in-situ catalyst systems that are efficient for the dehydrogenation of diphenyl methanol with the production of hydrogen as the only by-product. All four in-situ catalyst systems were generated by using commercially available ruthenium complexes, namely, RuCl3.nH2O, [Ru(p-cymene)Cl2]2, [Ru(benzene)Cl2]2 and [Ru(cod)Cl2]n and hexamethylenetetramine or its derivative as additive. All the developed catalyst systems were found to be efficient for the dehydrogenation of diphenyl methanol and [Ru(p-cymene)Cl2]2 was found to show best activity even while using 0.5 mol% of catalyst loading. The amount of H2 gas evolved during the ruthenium complex catalyzed oxidation of diphenylmethanol was measured using the gas burette method.
