| dc.description | A chemiluminescence-based analyzer of NO<sub>x</sub> gas species has been applied for high-throughput screening of a library of catalytic materials. The applicability of the commercial NO<sub>x</sub> analyzer as a rapid screening tool was evaluated using selective catalytic reduction of NO gas. A library of 60 binary alloys composed of Pt and Co, Zr, La, Ce, Fe or W on Al<sub>2</sub>O<sub>3</sub> substrate was tested for the efficiency of NO<sub>x</sub> removal using a home-built 64-channel parallel and sequential tubular reactor. The NO<sub>x</sub> concentrations measured by the NO<sub>x</sub> analyzer agreed well with the results obtained using micro gas chromatography for a reference catalyst consisting of 1 wt% Pt on γ-Al<sub>2</sub>O<sub>3</sub>. Most alloys showed high efficiency at 275 °C, which is typical of Pt-based catalysts for selective catalytic reduction of NO. The screening with NO<sub>x</sub> analyzer allowed to select Pt-Ce<sub>(X)</sub> (X=1–3) and Pt–Fe<sub>(2)</sub> as the optimal catalysts for NO<sub>x</sub> removal: 73% NO<sub>x</sub> conversion was achieved with the Pt–Fe<sub>(2)</sub> alloy, which was much better than the results for the reference catalyst and the other library alloys. This study demonstrates a sequential high-throughput method of practical evaluation of catalysts for the selective reduction of NO. |
