H2 Ti2 O5 nanotubes were synthesized by solvothermal method and applied in the acid catalytic esterification reaction.The as-prepared sample was characterized by means of X-ray powder diffraction and NH3-temperature programmed desorption.The results revealed that they have two acid sites, attributing to the weak and moderate-intensity acid sites.The esterification efficiency of acetic acid and n-butanol over H2 Ti2 O5 naotubes catalyst reached to 45.57%.
