✦ Synopsis

Acceleration of a mtalyzed reaction due to hot ehctron flow throufi a catalyst wils predicted and cxperimenttiy proved for formic acid decomposition on gold. Measurements were carried out with current densitks of (! to 1.5 .h!cn2

and with temperatures of 20 to 250°C.

During hot electron flow decomposition rates up to 100 times kger than the normal rates were obser,-eG when an effective power of 0.1 W/cm2 was applied, Surprisingly, a flow of Fermi electrons caused a slight decreese in decomposition rates.
