Carl Daniel Frisbie (born 1967) is a materials scientist and chemical engineer who is currently the Department Head and Distinguished McKnight Professor at the University of Minnesota (UMN). He is recognized for his wide-ranging research in organic semiconductors and printed electronics, and especially his contributions to the fundamental understanding of the synthesis and properties of electronic devices.

Experiments and Evidence
Catalytic rate enhancement via dynamic perturbation of surface active sites has been demonstrated experimentally using dynamic electrocatalysis and dynamic photocatalysis:


 * In 2020, dynamic oscillation of a catalyst above a static optimum rate was demonstrated for the first time. Using the formic acid electro-oxidation reaction, oscillation of the applied electrodynamic potential between 0 and 0.8 volts accelerated the formation rate of carbon dioxide more than an order of magnitude higher (20X) than what was achievable on platinum, the best existing catalyst.  The maximum catalytic rate was experimentally observed at a frequency of 100 Hz; slower catalytic rates were observed at higher and lower electrodynamic frequencies.  The resonant frequency was interpreted as the oscillation between conditions favorable to formic acid decomposition (0 V) and conditions favorable to form CO2 (0.8 V).


 * Dynamic promotion of methanol decomposition was demonstrated on 2 nm Pt nanoparticles using pulsed light. The rate acceleration to form H2 relative to static illumination was attributed to the selective weakening of adsorbed carbon monoxide, thereby also increasing the quantum efficiency of applied light.

Implementation of catalyst dynamics has been proposed to occur by additional methods using oscillating light, electric potential, and physical perturbation.
