摘要：Pd clusters supported on alkali titanate (Na- and K-titanate) nanobelts were synthesized and investigated for the catalytic HCHO oxidation at room temperature. The presence of interlayer alkali metal promoted the dispersion of Pd species and simultaneously made the Pd clusters more negatively charged, thus enhancing the catalytic performance for HCHO oxidation reaction at room temperature. Especially, Pd clusters with the smaller size and larger quantity of Pd-0 supported on K-titanate nanobelts contributed to higher catalytic activity and stability, where nearly complete HCHO oxidation was achieved with a Pd loading of 1 wt% at ambient temperature.
