摘要：

The effect of catalyst atomic ratio on the performance of styrene selective oxidation by H 2O 2 as probe reaction over spinel type strontium ferrate prepared through sol-gel method was investigated. The catalyst evaluation results showed that the optimum catalyst atomic ratio was n (Fe): n (Sr) = 2:1 with high catalytic activity. It was detected by XRD. The optimum calcination temperature was 700°C. Micro-structure and essence disciplinarian of strontium ferrate were disclosed. Under normal atmospheric pressure and 0.5 g catalyst dosage conditions, the optimum feed ratio, reactive temperature and reactive time were n (H 2O 2):n (Styrene) =1:1, 343 K and 9 h, respectively. The selectivity and yield of benzaldehyde were 65.7% and 34.3%, respectively. The technological process route possessed under ambient conditions with some advantage, such as excellent properties in product. It could provide experimental data and scientific evidence to develop from requirement of applications.
