Methanol synthesis from catalytic recycling of CO2 is one viable route to produce fuel and a stock chemical greenhouse gas. Herein, hydrogenation CH3OH investigated with density functional theory calculations combined mean-field microkinetic modeling. The model explores the direct for (HCOOH route) competing reverse water-gas shift (RWGS) reaction. predicted temperature dependence turnover freq...

The catalytic synthesis of cyclic carbonates using carbon dioxide as a C1-building block is a highly active area of research. Here, we review the catalytic production of enantiomerically enriched cyclic carbonates via kinetic resolution of racemic epoxides catalysed by metal-containing catalyst systems.

Evolution of the kinetic potential of enzyme reactions is discussed. Quantitative assessment of the evolution of enzyme action has usually focused on optimization of the parametric ratio kcat./Km, which is the apparent second-order rate constant for the reaction of free substrate with free enzyme to give product. We propose that the general form kcat.[E]T/Km (where [E]T is total enzyme concentr...

Catalytic steam reforming of methane for hydrogen production proceeds even at 473 K over 1 wt% Pd/CeO2 catalyst in an electric field, thanks to the surface protonics. Kinetic analyses demonstrated the synergetic effect between catalytic reaction and electric field, revealing strengthened water pressure dependence of the reaction rate when applying an electric field, with one-third the apparent ...

in this study, decolorization of the diazo dye, reactive black 5 (rb5) in a coprinus cinereus peroxidase-catalyzed reaction has been investigated. a bisubstate kinetic model for the reaction rate based on the ping-pong mechanism was assumed for the enzymatic decolorization. experimentswere conducted at different rb5 and hydrogen peroxideconcentrations in a batch mannerto estimate the intrinsic ...

High pH condition is of special interest for the potential applications of alkaline α-amylase in textile and detergent industries. Thus, there is a continuous demand to improve the amylase's properties to meet the requirements set by specific applications. Here we reported the systematic study of modular domain engineering to improve the specific activity and stability of the alkaline α-amylase...

Pyrolysis is an applicable method that has been widely used to recover hydrocarbons from Used Lubricating Oil (ULO). However, large-scale application of this approach has been limited by its noticeably energy and time consuming nature. In the present research, it has been attempted to modify the energy and time requirements of ULO pyrolysis using the catalytic effects of metal oxide nanoparticl...
