Magnetic-field-induced liquid phase catalysis over electrically conducting surface containing titanium dioxide

In general, heterogeneous catalytic reactions in liquid phase can be enhanced by manipulation of relevant local environment conditions. Since the magnetic field may affect the molecular processes of catalytic reaction on the catalyst’s surface, it is of interest to explore the effect of magnetic fie...
