| 英文摘要 | The sulfated vox-tio2 catalysts were synthesized by rapid combustion method. the catalytic properties were evaluated by the one-step oxidation of methanol to dimethoxymethane. it was found that the sulfate was highly dispersed on the catalyst surface as the sulfate content below 4 mol%, and aggregated as it was above 4 mol%. the former contributed to the increased number of acidic sites, while the latter decreased the number of acidic sites. the highest dmm selectivity (91.76%) was obtained with the sulfate content at 4 mol%, which should be attributed to its largest number of acidic sites and stronger reducibility.
