In the catalytic process, activation energy Revised 25 January 2018 over K-Pt/NaY nano-catalytic system was greatly decreased along with the enhanced reaction rate. Accepted 11 February 2018 Characterization and catalytic tests revealed the surface electron structure of K-Pt/NaY was improved, Available online 13 February 2018 as reﬂected by the enhanced HCHO adsorption capability, high AOH concentration, and low- temperature reducibility. Therefore, the optimal K-Pt/NaY showed high catalytic efﬁciency and strong Keywords: H
