Find issues by year (2011 - … AH represents the substrate, which is a hydrogen donor. Catalysis plays an important role in most processes for methane conversion to syngas. The native form of the enzyme does not often meet the requirements for large-scale use; therefore modulating the physicochemical properties becomes an essential part of product development at industrial scale. Fundamentally, the peculiar phenomenon of life would hardly be possible without the biological catalysts termed enzymes. (2015) compared the catalytic activity and selectivity of different reaction sites—low index (facet), edge, and corner sites—of silver (Ag) and gold (Au) icosahedral nanoparticles (AgNPs and AuNPs) for CO2 reduction (Fig. Core-shell, Iavicoli et al., 2014; Julkapli and Bagheri, 2015; Polshettiwar and Asefa, 2013; Varma, 2014, 2016, Green synthesis of polysaccharide-based inorganic nanoparticles and biomedical aspects, Functional Polysaccharides for Biomedical Applications, Gas phase heterogeneous partial oxidation reactions, José M. López Nieto, Benjamín Solsona, in, Catalytic applications of Janus nanoparticles, Edward Arenas-Calderon, ... Mónica Alejandra Guzmán, in. Prins, Photoswitchable catalysis by a nanozyme mediated by a light-sensitive cofactor, J. In addition, the Janus nanoparticles maintain strong adsorption with the average contact angles near 0° or 90°, where the surface activity of the homogeneous functionalized nanoparticles is low [13]. Chem. The presence of rGO has vital impact on catalysis activity due to its conduction properties. Hard work has been conducted for many years in order to optimize vanadyl pyrophosphate based catalysts, and the improvement observed is evident. A surface active particle shows a tendency to adsorb at surfaces, whereas an amphiphilic particle is one possessing a diblock structure in which the two blocks have different affinity for the oily and aqueous phase. Multifunctionality has also been considered and contributes to promote these materials as good candidates for heterogeneous catalysis. The surface activity of the particle is calculated as the desorption energy, which is defined as the free energy required to desorb the particle from the interface into either the bulk oil or water phase, (Eoil−Esurface) or (Ewater−Esurface), whichever is the lowest [13]. The industrial process challenges of these molecules and the in-depth response from the current catalytic players are well described in the chapter. The industrial catalysts used have been changing along the years; however, the changes of the nature of the catalysts have not been drastic since the main crystalline phase of the optimal catalysts remains the same. 3.6 [14].
