To guarantee high propylene yield, a good catalyst must have low hydrogen transfer, high accessibility and prevailing matrix technology to complement the right reaction system and reaction conditions.
First, transfers increase the accessibility of various destinations for users.
This theoretical production rate compares favorably with the experimentally determined formation rate of 117 nmol of benzyl acetate per hour and shows that the biocatalytic performance of our whole cell system is most likely not impaired by oxygen transfer and substrate accessibility as suggested for other whole-cell systems [ 23, 40].
Of note, additional factors known to influence the biocatalytic performance of a whole cell system such as, for example, medium composition, coexpression of chaperones, oxygen transfer, and substrate accessibility [ 23, 40, 43] were not considered in this study and therefore further improvement of our whole cell system is conceivable.
This new reactor design overcomes the problems of the external mass transfer effect and the accessibility to photons occurring in traditional reaction systems.
Mass transfer and hence the accessibility of the biomass to phenol was enhanced by decreasing the PVA particle size and increasing the air flow rate, which had a positive effect on the rate of biodegradation.
The superior performance of CGF composite may be ascribed to the unique hybrid microstructure, which can alleviate the stresses caused by volume variations, reduce charge transfer resistance, improve the accessibility of anode to electrolyte and increase the tapping density.
Our process to facilitate a position transfer comes down to accessibility and honesty.
The unique hierarchical micro-mesoporous shell of CANHCSs with large macroporous cores is advantageous for improving the catalytic activity because of enhanced mass-transfer kinetics and the accessibility of active sites in mesopores, accumulated electrolyte ions in micropores and large storage capacity of the electrolyte in macroporous cores [67].
Fabrication of hierarchical structure using GO could be desirable method to enhance catalytic activities by facilitating transfer ratio and increasing accessibility [65, 66], in addition to other methods based on supporting materials such as carbon black or metal oxide [39, 44].
