NOVELTY - Producing hydrogen involves (1) synthesizing oxyhydride material M1 electrically neutral based on cerium, nickel, oxygen or hydrogen atoms, preparing an aqueous solution comprising at least one cerium precursor, at least one nickel precursor and optionally at least one metal M precursor, coprecipitating the precursors in their corresponding hydroxide forms, filtering, drying and treating in the presence of hydrogen, and (2) contacting, at low temperature, the oxyhydride material M1 with a gaseous mixture comprising at least a lower alcohol, water and nitrogen and then contacting with oxygen.    USE - The process is useful for producing hydrogen (claimed), which is useful: as a source of energy to generate electricity and heat or motive power; as a gaseous fuel; and for fuel cells used in stationary systems in the fields of housing, industry and networks and in transport and mobile devices (phones and computers).    ADVANTAGE - The process is capable of economically producing hydrogen at low temperature with less energy consumption. The hydrogen reduces the overall dependence on fossil fuels and secondary emissions of greenhouse gases and air pollution.    DETAILED DESCRIPTION - Producing hydrogen by reacting an alcohol or an alcohol mixture, comprises (1) synthesizing oxyhydride material M1 electrically neutral based on cerium, nickel, oxygen or hydrogen atoms, where M is aluminum or zirconium, (1-i) preparing an aqueous solution comprising at least one cerium precursor, at least one nickel precursor and optionally at least one metal M precursor, (1-ii) coprecipitating the precursors of cerium, nickel, and the optional metal precursor M in their corresponding hydroxide forms by adding at least one precipitating agent to the aqueous solution, (1-iii) filtering the hydroxides to obtain a filtered solid, (1-iv) drying the filtered solid at a temperature of 40-150 degrees C for a time period of 1-24 hours to obtain a solid metal material M2 electrically neutral based on cerium, nickel, oxygen, hydrogen atoms and optionally a metal M and (1-v) treating the obtained solid material M2 in the presence of hydrogen to obtain a oxyhydride material M1, and (2) contacting, at low temperature, the obtained oxyhydride material M1 with a gaseous mixture comprising at least a lower alcohol, water and nitrogen and then contacting with oxygen, where the step (1) excludes a sub step of calcination. The material comprises nickel/cerium in a molar ratio of 0.1-5 and M/cerium in a molar ratio of 0-1, where at least a portion of hydrogen atoms in the material M1 is present in the form of hydride ions. The molar ratios of nickel/cerium and M/cerium are same as those relating to oxyhydride material M1, where at least a portion of the hydrogen atoms present in the material M2 forms hydroxyl functions with the oxygen atoms. The solid material M2 is free of hydride ions. An INDEPENDENT CLAIM is included for use of the oxyhydride material M1 as catalyst for the conversion reaction of lower alcohols into hydrogen at low temperature.
