The method can include supplying a titanium precursor gas into a reaction chamber, where the titanium precursor gas reacts with a base support of an anodic aluminum oxide, and the base support of an anodic aluminum oxide has a surface defining a plurality of pores therein. The reaction chamber can then be evacuated to remove any unreacted titanium precursor gas, and an alkoxide precursor gas can be supplied into a reaction chamber such that the alkoxide precursor gas reacts to with the titanium on the base support to form a hybrid titanium alkoxide. Thereafter, the base support cab be heated to remove the organic component to leave titanium oxide on the surface of the base support.

摘要： Systems and methods for hydrogen generation via ammonia decomposition that utilize a fixed bed reactor configured to receive inflows of NH3 and oxidant and to produce an outflow of high purity H2. The fixed bed reactor contains a fixed bed of a NH3 decomposition catalyst wherewith the NH3 decomposes to form N2 and H2; a plurality of ceramic hollows fibers with a high surface to volume ratio disposed in the fixed bed, the hollow fibers having an H2 selective membrane disposed thereon for extracting H2 from N2 and to form a permeate of the high purity H2 and a retentate of primarily N2; and a catalytic H2 burner also disposed in the fixed bed, the catalytic H2 burner for burning a portion of the H2 with the oxidant to provide thermal energy for the NH3 decomposition.
