Abstract

•Adding Ce, Pr and La improved catalytic activity of HZSM-5 for CH3SH decomposition.•The strong acidity decreased and the basicity increased after Ce, Pr and La addition.•Rare earth with different ionic radii caused different basicity of the modified catalysts.•La modified HZSM-5 exhibited higher catalytic activity than Ce and Pr doped catalysts.
