The present disclosure relates generally to ceramic materials suitable for use as catalyst support materials, catalysts using such materials and methods for using them, such as methods for converting sugars, sugar alcohols, glycerol, and bio-renewable organic acids to commercially-valuable chemicals and intermediates. One aspect of the invention is a ceramic material including zirconium oxide and one or more metal oxides selected from nickel oxide, copper oxide, cobalt oxide, iron oxide and zinc oxide, the ceramic material being at least about 50 wt. % zirconium oxide. In certain embodiments, the ceramic material is substantially free of any binder, extrusion aid or additional stabilizing agent.

Method for the reduction of a sugar, sugar alcohol or glycerol

The present development is a catalyst composition, comprising zinc oxide nanowires having one or more catalytically-active metal particles attached to a surface of the zinc oxide nanowires. The catalytically-active metal particles are comprised of a metal selected from the group consisting of nickel, cobalt, molybdenum, tungsten, copper, and platinum. The present development further discloses a method to prepare the catalyst composition, and use of the catalyst composition for desulfurization.

Catalyst composition and methods for desulfurization

The present disclosure relates generally to catalyst support materials, catalysts and methods for using them, such as methods for converting sugars, sugar alcohols, glycerol, and bio-renewable organic acids to commercially-valuable chemicals and intermediates. One aspect of the invention is catalyst support material including ZrOand one or more oxides of manganese (MnO), the catalyst support material being at least about 50 wt % ZrOand MnO. In certain embodiments, the weight ratio of ZrOto MnOis within the range of about 1:1 to about 30:1; and/or the catalyst support material is substantially free of any binder, extrusion aid or additional stabilizing agent.
