Quantitative Physical Chemistry of Heterogeneous Catalysis: From Microkinetics to Multiphysics Reactor Design

Abstract Quantitative understanding of catalysis requires more than comparison of apparent activity. It begins by establishing whether a measured rate represents intrinsic surface chemistry or is influenced by mass transfer, heat transfer, reactor geometry, or catalyst evolution....

Preferential Nucleation Sites Regulate Hydrogen Bubble Evolution on Mesh Electrodes

Gas-bubble evolution substantially affects the efficiency of gas-evolving electrochemical processes, including water electrolysis. Bubble nucleation, growth, coalescence, and detachment influence the electrode potential, while persistent bubble coverage can impede ionic...
