Platinum or platinum group metal decorated non-oxide materials that are formed using a synthesis pathway that avoids the production of intermediate oxides. The materials are suitable for use as catalysts and may or may not be porous.

Highly dispersed and durable heterogeneous catalysts

Novel materials having high surface area rendering them suitable for a variety of applications including, but not limited to: catalysts for methane reforming; ammonia synthesis; alcohol synthesis from syngas; hydrodesulfurization; electrocatalysis for hydrogen evolution reaction; and as corrosion-resistant supports for platinum in PEM fuel cells. In general the method comprises the formation of a high-surface area refractory metal-based material using a novel synthesis pathway that avoids the production of intermediate oxide. The method may include the in situ formation of a sacrificial support that can be removed using non-aggressive means, such as, for example, chemical etching with a mild acid or by altering reaction conditions.

Method for synthesis of functional ceramic materials

Mesoporous conductive niobium and niobium-ruthenium particles and methods for forming the same are described. In some cases the particles are suitable for use as a fuel cell catalyst. The described aerosol-based synthesis method allows for single step formation and processing of the particles.

The present invention provides for evaporation induced self-assembly (EISA) within microdroplets produced by a vibrating orifice aerosol generator (VOAG) for the production of monodisperse mesoporous silica particles. The process of the present invention exploits the concentration of evaporating droplets to induce the organization of various amphiphilic molecules, effectively partitioning a silica precursor to the hydrophilic regions of the structure. Promotion of silica condensation, followed by removal of the surfactant, provides ordered spherical mesoporous particles.
