Resumen:
Nickel-TiO2 hybrid catalysts are synthesized by electrodeposition and their catalytic activity with respect tothe hydrogen evolution reaction is analyzed. Two types of titanium oxide particles, which are commercial particlesof dense TiO2 and mesoporous TiO2 particles synthesized by an aerosol method, are incorporated intothe matrix of the nickel catalyst,. Both nickel catalysts containing TiO2 particles presented higher catalyticactivity than the conventional nickel Watts catalyst. Mesoporous TiO2-modified nickel catalyst showed thehighest catalytic activity towards HER in alkaline medium. In addition, this type of nickel catalyst increasesits catalytic activity after ageing treatment, which is an indication of an increase in the electro-active area ofthe electrode.
