文摘

Alkali metals doped Pd catalysts were employed in the hydrogenation reaction. The catalysts doped by alkali metals exhibited different catalytic performance. 84.79% benzotriazole selectivity was obtained over K doped catalyst. K doped catalyst could run over 100 h without obvious deactivation. Basic sites of K doped catalyst distribute around Pd particles strictly.
