Biocatalysis: Fundamentals and Solvent Parameters
(Elsevier, 2020) Acidereli, H.; Sogut, E.G.; Mustafov, S.D.; Gulcan, M.; Sen, F.
Biocatalysis involves the use of one or more enzymes to catalyze chemical reactions. Compared to conventional methods, biocatalysis has advantages such as high stereo-, regio-, and chemoselectivity, efficient catalysis, both complex and straightforward transformations, low rate of by-product formation, inexpensive refining and purification (uncomplicated), mild reaction conditions, and reduced impact on the environment by reducing waste production. To have these advantages, the solvent character of the enzyme should be optimally determined. Thus, all the advantages of biocatalysis are utilized. In this review, it has been tried to present the parameters that will provide optimum conditions for biocatalysis. Biocatalysis, which facilitates many disciplines, is the most popular subject in the catalysis field due to its unique facilities and still undiscovered features. © 2021 Elsevier Inc.

Hydrogen Generation by Hydrolysis of Nabh4 Using Nanocomposites
(Elsevier, 2020) Kızıltas, N.; Karatas, Y.; Gulcan, M.; Mustafov, S.D.; Sen, F.
Alternative energy sources are needed while maintaining sustainable atmospheric greenhouse gas levels to meet global energy demands. Our current use of hydrogen for a sustainable energy system has been promising due to its sustainability, environmental emissions, and energy security. In addition to being used as fuel, great efforts are being made to safely produce, store, and transport hydrogen. The hydrogen storage model is developed to meet the need for sustainable energy, the hydrogen produced by the electrolysis of water using photovoltaic panels, that is, by using electrical energy with generators, stored using the hydrolysis of sodium borohydride. Significant progress has been made with this model, which seeks to meet optimum conditions in terms of high density, high stability, and safety. The studies suggest that the reaction of sodium borohydride is an essential chemical in the introduction of hydrogen into portable fuel cells due to its ease of control and nontoxicity. In this chapter, NaBH4 properties are examined as an energy source, and environment-based hydrogen/energy carriers are summarized. Moreover, its use as a reducing agent and hydrogen carrier, and hydrogen production by hydrolysis and thus developed catalytic systems are discussed in terms of environmental and economic concerns. © 2021 Elsevier Inc.
