摘      要：Nickel-Ti O_2 hybrid catalysts are synthesized by electrodeposition and their catalytic activity with respect to the hydrogen evolution reaction is *** types of titanium oxide particles,which are commercial particles of dense Ti O_2 and mesoporous TiO_2 particles synthesized by an aerosol method,are incorporated into the matrix of the nickel *** nickel catalysts containing Ti O_2 particles presented higher catalytic activity than the conventional nickel Watts *** TiO_2-modified nickel catalyst showed the highest catalytic activity towards HER in alkaline *** addition,this type of nickel catalyst increases its catalytic activity after ageing treatment,which is an indication of an increase in the electro-active area of the electrode.
