NOVELTY - Preparation of alkali metal modified nickel-tin material involves (s1) placing alkali metal citrate in deionized water to prepare mixed solution (A) or placing citric acid, alkali metal carbonate and/or alkali metal bicarbonate in deionized water, (s2) adding nickel salt and tin salt to prepare mixed solution (B), and (s3) heat-stirring until the water is evaporated, drying, grinding, and pyrolyzing at 450-550℃ in a nitrogen atmosphere. The molar ratio of citrate ions to alkali metal ions in the mixed solution (A) is 1:(2-21). The molar ratio of nickel ions to tin ions to alkali metal ions in the mixed solution (B) is 1:(0.025-0.2):(0.1-30). USE - Preparation of alkali metal modified nickel-tin material for catalyzing ethanol aqueous phase to synthesize 6C or more carbon products (all claimed). ADVANTAGE - The catalyst can effectively promote ethanol conversion and improves the selectivity of the 6C or more carbon products. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for alkali metal modified nickel-tin material.
