Modulation excitation pair distribution function experiments in catalysis to increase phase sensitivity

Nanoscale, vol. 17, pp. 18766–18776

Abstract

Phase-sensitive detection analysis of PDF data taken under modulation excitation conditions of catalytic cycling considerably improves the PDF data quality of Ni@Al 2 O 3 catalysts, revealing subtle changes occurring under operating conditions.
