A Received 4 March 2015 homogeneous stock solution of a Ni catalyst was prepared, conserved and used for an alkali electrolyte Received in revised form 26 May 2015 with no precipitation due to the coordinative and protective effects of sodium tartrate and polyvinyl Accepted 31 July 2015 pyrrolidone (PVP). The deposition of the Ni(OH)2 catalyst and its electrocatalysis toward glycerol Available online 3 August 2015 occurred nearly simultaneously. Tedious and laborious procedures for preparing common catalysts and immobilizing them on an electrode surface were not required. The Ni(OH)2 catalyst film self-repaired due Keywords: to the presence of Ni in the alkali electrolyte. This technique a
