In a method of producing a particulate electrocatalyst composition, a precursor medium comprising at least a first metal precursor, a liquid vehicle, and a substrate precursor to substrate particles is atomized into precursor droplets. The droplets are then heated to a reaction temperature of not greater than 700&#xb0; C. to form composite particles comprising said first metal at least partly in an oxide form dispersed on said substrate particles. The composite particles are then collected and are heated at a first treatment temperature no greater than 250&#xb0; C. in the presence of a reducing atmosphere to at least partly convert said oxide form to the metal.

Materials that are useful for absorption enhanced reforming (AER) of a fuel, including absorbent materials and catalyst materials and methods for using the materials. The materials can be fabricated by spray processing. The use of the materials in AER can produce a Hproduct gas having a high Hcontent and a low level of carbon oxides.

Processes for forming catalyst particles utilizing a defoamer are described. Also described are processes for forming catalysts, where the processes comprise providing a correlation between defoamer concentration and catalyst particle morphology, and determining an amount of defoamer to include in a precursor composition to obtain the target morphology based on the correlation.

Processes for controlling catalyst particle morphology

Solid absorbent materials that are useful for absorption of chemical species from a fluid, such as a gas stream or a liquid stream. The absorbent materials are formed by spray processing and posses a well-defined chemical composition and microstructure. The absorbent materials can have a high absorption capacity for a chemical species such as HS, CO, NO, and Hand have a high recylability, such that the chemical species can be absorbed and desorbed over a large number of cycles.

The materials can be fabricated by spray processing. The use of the materials in AER can produce a Hproduct gas having a high Hcontent and a low level of carbon oxides.

Materials that are useful for absorption enhanced reforming (AER) of a fuel, including absorbent materials and catalyst materials, and methods for using such materials for the conversion of carbon-based fuels to a H-rich product gas. The materials can be fabricated by spray processing. The use of the materials in AER can produce a Hproduct gas having a high Hcontent and a low level of carbon oxides. The method for converting carbon-based fuels to a H-rich product gas includes forming an intermediate gas product from the carbon-based fuel using a catalyst and contacting the intermediate gas product with an absorbent to absorb CO. The absorbent can be regenerated while retaining a high absorption capacity.

A process for making particles, the process including generating an aerosol stream which includes droplets of a precursor liquid dispersed in a carrier gas, the precursor liquid including a liquid vehicle and a precursor material, separating the precursor liquid into two portions during the generating step, a first portion exiting the generator in the droplets of the aerosol stream and a second portion exiting as effluent at least a portion of which is recycled to the generator, and also during the generating step adding additional liquid vehicle to at least one of the carrier gas supply, the precursor liquid supply, and the aerosol generator, to at least partially compensate for the tendency of the precursor liquid to become more concentrated in the precursor material over time, and then removing at least a portion of the liquid vehicle from the droplets and forming particles in the aerosol stream.
