A nonthermal chemicurrent effect of hydrogen adsorption on Pt/SiC planar nanostructures at normal ambient conditions

► Nonthermal chemicurrents induced by H2 adsorption on Pt/SiC nanostructures shown. ► The process occurs at normal gas pressure and room temperature conditions. ► Thermal effect is reproduced by N2 admission with no resultant current observed. ► Chemicurrents of this type help to understand H2 evolution on catalytic surfaces.
